Abstract:

The bread-making quality of forty commercial winter wheat samples, grown in the western region of the CzechRepublic, and their flours (white flours with ash content of about 0.5%) prepared in a commercial mill was studied. Standard analytical methods (ash and protein content, wet gluten), amylolytic activity measurement (falling number), rheological investigation (alveograph, gluten index), sedimentation test and laboratory baking test were used for characterization of wheats and flours. In addition NIR method was used to calculate ash, wet gluten, sedimentation value and protein content. Statistically significant correlations were found practically between all tested quality parameters of wheat and corresponding flour samples. However, the strongest correlation (r = 0.69–0.70) significant at 0.01 level exists between specific bread volume and protein and wet gluten content, determined both by standard or by NIR methods.

Abstract:

This study was conducted to assess the procedure of fish feed production, analysis of nutritive value of feeds and its effect on growth of fish in selected fish farms. Five fish feed mills and fifteen fish farmers were randomly selected from Mymensingh district. Fish feeds were used by fifteen farmers among every three farmers used the feed of each mill. These feed Mills collect their Saudi Bangla and ACME fish feed are more preferable to the farmer due to higher protein and lipid content resulting more fish production. In this experiment, Saudi-Bangla fish feed mill (3843 Kg/ha/yr), Sunny fish feed mill (3761 Kg/ha/yr), Shushama fish feed mill (3581 Kg/ha/yr), Al-momen fish feed mill (3669 Kg/ha/yr), ACME fish feed mill (3796 Kg/ha/yr) was produce fish. Capital cost, operating cost, depreciation cost, total cost, revenue income and net profit were calculated and evaluated during the experimental period. In this study, those feed mills production capacity was 45000 ton/yr Saudi-Bangla fish feed mill, 45000 ton/yr Sunny fish feed mill, 35000 ton/yr Shushomo fish feed mill, 35000 ton/yr Al-momen fish feed mill,15000 ton/yr ACME fish feed mill. The fish production mainly carps and pangus were highly occurs chronologically Saudi-Bangla, ACME fish feed, Sunny fish feed, Al-momen fish feed, Shushama fish feed mill, respectively. Among those the nutritive value of Saudi-Bangla fish feed was the best than other fish feed.Res. Agric., Livest. Fish.2(2): 353-362, August 2015

Abstract:

Side milling tests of CFRP (carbon fiber reinforced plastics) containing thermosetting resin are carried out by TiAlN/AlCrN-coated, H2-free DLC (diamond-like carbon)-coated, and CVD diamond-coated carbide end mills without coolant. Two types of end mills having different helix angles of 30° and 60° are used. The film thickness and surface smoothness are varied for the DLC-coated end mills. The cutting characteristics are evaluated by tool wear and surface integrity (i.e., 3D profiles of the machined surface, generation of fluffing, delamination, and pull-out of the carbon fibers). The cutting force and tool flank temperature are also examined for the two types of CFRP composites and the helix angle of the end mill. “Inclination milling,”in which the end mill is tilted so that the resultant cutting force acts parallel to the work surface, is proposed as a novel technique to be used with a high-helix angle end mill. This unique approach enables the reduction of tool wear and improves the surface integrity of machined CFRP surfaces.

Abstract:

Abstract. During the pelleting process, conditioning temperature can influence nutrient availability and pellet durability index (PDI). However, the impact of conditioning temperature on nursery pig growth performance is variable. Therefore, the objectives of two experiments were to: (1) compare moisture percentage among three pellet mill series, and (2) quantify growth performance differences in nursery pigs due to diet form (mash vs. pelleted), conditioning temperature (low, medium, and high), and pellet diameter (4.0 mm and 5.2 mm). Experiment 1 was a 3 × 4 factorial design with three pellet mill series of decreasing capacity (medium, small, and experimental-scale; California Pellet Mill Co., Crawfordsville, Indiana, for a medium, small, and experimental pellet mill, respectively) that produced samples collected at four locations (initial, post-conditioner, post-die, and post-cooling). Three runs were completed on each pellet mill, with the shutdown of the pellet mill indicating the end of a run. Three samples were collected from each location per run, for a total of 36 samples. Experiment 2 used 350 nursery pigs (DNA 200 × 400; initially 7.6 kg) in a 28 d experiment fed two phases, with a phase change at day 14. Seven treatments were arranged in a 2 × 3 factorial design plus an unpelleted mash control, with the factors of pellet diameter (4.0 mm and 5.2 mm) and conditioning temperature (low, medium, and high). Data were analyzed using the GLIMMIX procedure of SAS (version 9.4). In experiment 1, there was a significant pellet mill × location interaction (p = 0.012) for moisture percentage. Because moisture is added via steam at the conditioner, only the conditioning location results are described. Regardless of pellet mill type, moisture was highest in conditioned samples. However, conditioned samples from the experimental-sized pellet mill had over 1% greater (p < 0.05) moisture than samples from the medium and small pellet mills. This increase in moisture is one reason why higher (p < 0.05) PDI values were found in pellets from the experimental pellet mill compared to the medium and small pellet mills. In experiment 2, increasing conditioning temperature improved (p < 0.0001) PDI. The interaction of pellet diameter × conditioning temperature did not impact (p > 0.10) overall nursery pig feed efficiency (G:F). However, for overall G:F, both main effects tended to be significant (p < 0.10), which was caused by pigs having greater (p < 0.05) G:F when fed larger-diameter pellets conditioned at a low temperature, compared to pigs fed smaller-diameter pellets conditioned at a high temperature. Regardless of parameter, pigs fed pelleted diets had 4.5% greater (p < 0.05) G:F than those fed mash diets. In summary, pellet mill size is important to consider when evaluating factors that impact pellet quality, such as percentage moisture. Increasing conditioning temperature is one method to improve PDI, but there was a tendency to reduce nursery pig G:F when feeding two phases of diets in a 28 d study. In conclusion, conditioning feed at lower temperatures may improve nursery pig G:F when starting pigs on a new diet. Keywords: Moisture, Pelleting, Starch.

Abstract:

Nowadays, ball mills are widely used in cement plants to grind clinker and gypsum to produce cement. The research focuses on the mill speed as well as air classifier speed effect on the two compartment Cement ball mill performance in terms of Blaine, Sulphur trioxide contents, mill power, mill residue and mill residence time. Special importance was assigned to the study of the specific surface area and the surface area production rate, both during the variation with the mill speed and the air classifier speed. Within the content of this work, sampling campaigns were organized around a cement grinding circuit and varying cement ball mill speed as well as an air classifier speed at various dosage feed rate. The fact that such an examination has not been made previously by using industrial data rather than lab scale makes this work unique. The fineness is measured in terms of Blaine number. Mill speed and air classifier speed were the investigating parameters. It was deduced that depending on the speed of mill and air classifier, their effects on Blaine, SO3, mill power and mill performance were varied, ultimately all of them improved the performance of grinding and classification operations. The rapid expansion of ceramic wastes in China has raised great many interests in their sustainable uses in building materials The micro ceramic powder can be taken as a supplementary cementitious material to replace cement up to 40% for tuning the microstructure and mechanical properties of blend cement materials. The Blaine quality dictates strength, setting time and overall performance of cement. Optimum performance of ball mill could potentially refine Blaine fineness, thereby improving the cement quality. This study investigates the effects of separator speed and mill speed on Blaine fineness, mill residue, consumed power. Five speed levels used in closed cycle grinding mill are 200, 400, 600, 800 and 1000 rpm. The capacities were determined to obtain product Blaine surface areas in the limits between 2000 cm2 / gram and Variations in clinker feed rate, mill speed and separator speed could proportionally impact the grain quality of Blaine. When the separator speed is increased from 850 to 900 rpm the Blaine is increased from 2800 to 3000 cm2/g and mill residue decrease from 15 to 10 microns. Therefore, optimum parametric combination could reduce power consumption while improving the cement quality. Knowledge of effects of parametric variations on the quality of end product could be helpful for controlling product quality. Furthermore, proper grinding of clinker produces fine Blaine at first place and reduces the need for recycling of coarse grains.

Abstract:

The characterization of Lycopersicon germplasm for internal quality properties is essential to choose suitable donor parents for breeding programs. When donor parents belong to species of subgenus Eulycopersicon, which are phyletically closer to L. esculentum Mill., the recovery of agronomic traits is faster. When using these materials, a careful selection of donor parents which could improve several internal quality properties allows the acceleration of these breeding programs. In this work, we combine general determinations, such as soluble solid content, titratable acidity, pH, total sugars, pectic substances and total protein contents with precise high-performance liquid chromatography (HPLC), quantitations of individual compounds (vitamin C; citric, malic, fumaric and oxalic acids; glucose, fructose, and sucrose), in order to obtain a more complete characterization of flavor intensity and nutritional properties in Lycopersicon germplasm. The multidimensional analysis of all these variables allows classification of several accessions of L. esculentum Mill. and L. pimpinellifolium (Jusl.) Mill., according to their usefulness for internal quality breeding programs of fresh tomato. The classification obtained and the comparison of accessions quality characteristics with selected controls show that five of the L. pimpinellifolium (Jusl.) Mill. accessions tested can be of great usefulness for being used in breeding for internal quality characteristics. A flavor intensity ≈625% higher than commercial hybrids was obtained in the best accession tested. Some of these L. pimpinellifolium (Jusl.) Mill. accessions showed better flavor intensity properties than a high SSC L. cheesmanii Riley control, traditionally used in internal quality breeding. In addition, three of the L. esculentum Mill. accessions tested with medium-to-high flavor intensity value could be useful in advanced stages of breeding programs.

Abstract:

In recent years there is an emerging trend of coarse grinding of cereals in production of poultry feed due to positive influence of coarse particles on poultry digestive system. Influence of grinding method (hammer mill vs. roller mill) and grinding intensity of corn (coarseness of grinding) on mill specific energy consumption and pellet quality was investigated. By decreasing grinding intensity of corn (coarser grinding), specific energy consumption of both hammer mill and roller mill was significantly decreased (p < 0.05). When comparing similar grinding intensities on hammer mill and roller mill (similar geometric mean diameter or similar particle size distribution), specific energy consumption was higher for the hammer mill. Pellet quality decreased with coarser grinding on hammer mill but, however, this effect was not observed for the roller mill. Generally, pellet quality was better when roller mill was used. It can be concluded that significant energy savings could be achieved by coarser grinding of corn before pelleting and by using roller mill instead of hammer mill. From the aspect of pellet quality, if coarser grinding is applied it is better to use roller mill, concerning that more uniform particle size distribution of corn ground on roller mill probably results in more uniform particle size distribution in pellets and this provides better pellet quality.

Abstract:

Mill-grinding experiments were carried out on SiCp/Al to investigate effects of mill-grinding parameters and grinding wheel parameters on machined surface roughness in this paper. The machined surface topography was also analyzed. Experimental results show that surface roughness increases with increasing feed rate and the depth of the mill-grinding. The effect of mill-grinding speed on surface roughness is low. The machined surface reveals many defects. The fine grit diamond grinding wheel can reduce the surface roughness and decrease the machined surface defect. Compared to the vitrified bonded diamond and electroplated diamond grinding wheels used in the experiment, the resin-based diamond grinding wheel produces a better surface.

Abstract:

Wheat is one of the most important cereals in the world and the bread made of its flour belongs to the everyday life of human mankind.The Hungarian standard relating to the laboratory production of wheat flour (MSZ 6367/9-1989) does not mention the type of laboratory mill used for milling, and it only builds up some general criteria, such as: the laboratory mill should be provided with four differently nicked barrels, a sieve with appropriate hole sizes, and also with the separated collections of the pilot flour and the bran. Our study was started at this point and the answers for the following questions were aimed to be found: do the flour patterns studied and produced with different grinding and sievingtechniques, widely used in laboratory mills of the same wheat pattern show any alterations after the impact of the formula production as regards chemical constitutions and reologic parameters. Various flours and whole grains of the wheat patterns sieved with different particle sizes were studied in this experiment. In producing this pattern two different mill types of FQC 109 and CHOPIN CD 1 as well as two different grinder types such as PERTEN 3100 and type of RETSCH 200 were applied. There were 3 different corn sizes of 160; 250; 800 μms used in the partition of the fractions. To study the differences the following measurements were conducted: dry matter, ash, protein content, wet gluten content, gluten index, gluten expansiveness, farinographic value, falling number and amilographic rate.The results this research confirm that the quality of wheat flour can be modified by different methods of pattern production. In all cases the differences can be explained by the flour-bran ratio, and in some of the cases the higher germ content of the fractions also played a role. The results show differences between the various types of mills and grinders, too.

Abstract This paper deals with the influence of the end mill helix angle on the flatness and surface quality of aluminium (EN AW 6082) thin-walled parts. The three teeth solid end mills of 12 mm diameter with same and different helix angle of third tooth were designed. The tests were performed using the HSC 105 linear CNC machine and following cutting parameters: cutting speeds (800, 100 and 1200 m.min−1), feed per tooth (0.12 mm), cutting depth (for roughing 10 mm and for finishing 5 mm). Evaluation of surface quality of the processed thin-walled parts shows that the helix angle of the end mills has a significant influence on the surface quality of the thin-walled parts. The best results were obtained in the case of end mill with different 35° helix angle of third tooth and cutting speed 1000 m.min−1.

Abstract:

This study is to determine the properties and characterization of silicon carbide via grinding and heat treatment process. In this study, the raw materials used were waste glass and graphite powder. Silicon carbide was produced by milling and mixing waste glass and graphite powder in different grinding mills; planetary mill and ring mill. The samples were then heat treated at 700 °C for 1 hour soaking time. Two types of characterization procedures were completed to determine the properties and microstructure of silicon carbide. Formation of silicon carbide was only formed through grinding by planetary mill but not ring mill. This may due to the grinding mechanism of both mills. Due to the simple and low cost of raw material to form silicon carbide, silicon carbide has high potential to be one of the commercialized products. It has the potential in reducing waste and improves the environment quality.

Abstract:

AFRP(Aramid Fiber Reinforced Plastics) is widely used in the aerospace and automotive while there are many problems in machining AFRP such as furry, delamination, burns and so on. Milling experiments of AFRP have been conducted to study the influence of different helix angle (0°, 30°, 60°) and cutting tools (traditional end mill, multiple flute end mill and compression end mill) on cutting force and machined surface quality. The results indicated that the cutting force has been reduced and the surface quality has been improved with the increase of helix angle. The cutting tool structure can make greater influence on machined surface quality than the cutting parameters. A cutting tool with the structure of multiple flute or herringbone cutting edge could reduce the axial cutting force. However the cutting force is too small to cut off fibers when using a multiple flute end mill. A good processing surface can be achieved while cutting with a compression end mill or a tool with big helix angle.

Abstract:

The quality of cotton fiber observed at classing depends on the production conditions (soil, variety, climate, and crop management practices, including harvesting technique) and on the ginning conditions (seed-cotton cleaning, ginning, and lint cleaning). Thus, when lint quality is monitored, variations in seed-cotton quality may be confused with the impact of variations in ginning conditions. So, rather than measuring the quality of the cotton leaving the ginning mill, we propose measuring the impact of ginning conditions on the difference in quality between a batch of cotton ginned in the mill and a sample of the same batch ginned using micro-ginning equipment. By comparing 11 industrial ginning mills with the micro-ginning equipment used as a control, this feasibility study evaluated the impact of ginning conditions in an experiment on 119 seed-cotton modules in Mali throughout the 2014–2015 season. Based on this comparison, data analysis showed that the ginning process did have an impact on cotton quality, that the impact varied with the date, and that it was only linked to ginning conditions. Conversely, no alert concerning the impact of industrial ginning conditions was issued based on the results of the evaluation of the quality of fiber samples from industrial ginning mills alone.

Abstract:

The study aims to examine the profitability and forward linkage analysis of poultry feed covering Dhaka, Gazipur, Narsingdi, Kishoreganj and Mymensingh districts. In total 30 feed mills which categorized such as high, medium and low quality on the basis of feed conversion ratio along with 45 dealers; 15 sub-dealers and 120 farmers purposively. The primary data were collected during March 2013 to March 2014 by using survey schedule, KII and FGD. In addition, the secondary data were collected from different government documents. It is evident that the cost of feed was found Tk. 39295, Tk. 38643 and Tk. 37218 per MT (metric ton) respectively for high, medium and low quality feed mills. The gross returns were found Tk. 43160, Tk. 42330 and Tk. 40500 per MT and gross margin was Tk. 6486, Tk. 5957 and Tk. 5285 per MT respectively. The net returns were found Tk. 3865, Tk. 3687and Tk. 3279.2 per MT respectively. It indicates that total gross return, gross margin and net return of high quality feed mill is higher than medium and low quality feed mill. It is also evident that about 60% of raw materials were purchased from Dinajpur, Rangpur, Rajshahi, Jamalpur and coastal areas namely Bagergerhat, Chittagong and Khulna where as 100 percent of feed additives were imported. The unavailability of raw materials was the major problems for feed mills operation which influenced feed price and quality. If these problems could be solved within a reasonable time, stakeholders would be able to get more benefits and run business smoothly.J. Bangladesh Agril. Univ. 14(2): 201-208, December 2016

Abstract:

Electro-polishing was used as an alternative to mechanical polishing for the cutting edge preparation of tungsten carbide (WC) ball nose end mills. High-quality cutting edge surfaces with roughness of magnitude 0.3–0.35 µm was achieved using the electro-polishing process. A direct current of 0.96 A was passed through an electrolytic cell containing the electrolyte sodium hydroxide with a concentration—2.5 mol/dm3. The ball nose end mill was suspended as the anode and a stainless steel (SS304) as the cathode. The ball nose end mill was electro-polished using the optimized parameters which was obtained through performing the preliminary experiments on tungsten carbide coupons of size D6 × 20 mm. The effects of electro-polishing on the surface texture of the ball nose end mill were determined using surface texture examinations. Machining tests were conducted on Ti6Al4V alloy to understand the growth of flank wear on the electro-polished ball nose end mills. After every 5 m of cutting distance, flank wear measurements were done for both the regular ball nose end mill and the electro-polished ball nose end mills. The results revealed that the electro-polished ball nose end mill reached a flank wear of 0.15 mm after a cutting distance of 550 m. This was significantly more than the cutting distance of the standard ball nose end mill of magnitude 350 m for the same amount of flank wear. This showed an increase in tool life of over 50%.

Abstract:

During the cycle 1 environmental effects monitoring (EEM) studies, wild fish collected downstream of several Nexfor Canadian pulp mills indicated reduced gonad size or fecundity. A two-year collaborative study between Nexfor Inc. and the National Water Research Institute of Environment Canada was begun to investigate the reproductive responses. The purpose of the study was to assess final effluents from Nexfor Canadian mills for their ability to affect goldfish circulating sex steroids (testosterone, 11-ketotestosterone) or production of steroids in vitro by testes from exposed fish. Along with final effluent, individual waste streams from the mill processes were tested to investigate the potential source(s) of steroid-disrupting compounds from within the mill. The study also provided a chance to study effluent potencies over time as mill processes were changed and upgraded. Goldfish exposed for 16-21 days to final effluent (100%) from a bleached sulphite mill (BSM) showed reduced testosterone and 11-ketotestosterone production by testes. Testes of goldfish exposed to undiluted final effluent had steroid production one-tenth that of controls. Fish exposed to individual waste streams (2-40%) had steroid production similar to control fish. It was difficult to assess the waste streams, as fish-exposure concentrations were inconsistent among waste streams due to differences in the acute toxicity of streams. Final effluent from the same mill collected one year later, after numerous mill upgrades (such as changes in chip handling, digester operation and better control of spills), showed an improvement: Goldfish exposed to 100% effluent had normal steroid levels. The study demonstrates the use of the goldfish steroid bioassay for detecting changes in effluent quality. Changes in processes at the mill in the year following the fish tests resulted in final effluent that had no deleterious effects on fish testes production of steroids. The environmental consequences resulting from the improvement in BSM final effluent quality will be tested during the cycle 2 EEM.

Abstract:

The MWV mill in Covington, VA, USA, experienced a long term trend of increasing episodes of paper indents that resulted in significant quantities of internal rejects and production downtime. When traditional troubleshooting techniques failed to resolve the problem, big data analysis techniques were employed to help determine root causes of this negative and increasingly frequent situation. Nearly 6000 operating variables were selected for a deep dive, multi-year analysis after reviewing mill-wide process logs and 60000+ PI tags (data points) collected from one of the major data historian systems at the MWV Covington mill. Nine billion data points were collected from November 2011 to August 2014. Strategies and methods were developed to format, clean, classify, and sort the various data sets to compensate for process lag time and to align timestamps, as well as to rank potential causes or indicators. GE Intelligent Platforms software was employed to develop decision trees for root cause analysis. Insights and possible correlations that were previously invisible or ignored were obtained across the mill, from pulping, bleaching, and chemical recovery to the papermaking process. Several findings led the mill to revise selected process targets and to reconsider a step change in the drying process. These changes have exhibited significant impacts on the mill’s product quality, cost, and market performance. Mill-wide communications of the identified results helped transform the findings into executable actions. Several projects were initiated.

Abstract:

The rheological and physical properties of the chocolate mass depend on the ingredient composition as well as the manufacturing process. For the purpose of this work, a milk chocolate mass of identical composition and raw materials was manufactured by using the two different manufacturing processes: a standard manufacturing process (SM) in five-roller mills including conching, and an unconventional manufacturing process in a ball mill (R1). The quality of both milk chocolate masses was examined by the comparison of thermal (differential scanning calorimetry analysis), textural properties (texture analysis), and the content of hard triglycerides (nuclear magnetic resonance spectroscopy). The main goal of this work was to determine whether chocolate can be produced in a ball mill, using the manufacturing process which results in significant savings, without causing drastic changes to the chocolate physical properties. The new manufacturing process rationalises the standard method by combining two phases, namely conching, and refining into a single one. This results in reduced initial and maintenance costs, as well as costs of workforce and fuel, etc. The results have shown that the new chocolate manufacturing process has a positive impact on texture and thermal properties, while the content of hard triglycerides remains the same.

Abstract:

In cold rolling process, asymmetric shape defects are still a common problem to strip quality. For the mills with inverse symmetry roll shifting system, different roll wear and thermal contour of top roll system and bottom roll system could cause asymmetric shape defects during shifting operation. In this paper, three dimension finite element simulation models of inverse shifting roll system were established to calculate the parameters and to analyze the effects. Based on the idea in the mill engineering that mill style option depended on the product grade, shifting weakness was evaluated and the opinion of limit shifting was suggested. To improve control effect to asymmetric shape defects in cold rolling, shape control system with asymmetric shape control ability is developed, including asymmetric edge drop control at upstream stands and asymmetric flatness control at last stand. The further improvement of asymmetric shape control theory and practice is the key way to reach the higher precision of shape quality in cold strip mills.

Abstract:

The 3-roll Reducing and Sizing block RSB has been known as reliable instrument for the economic production of SBQ and wire rod. By continuous development of the RSB technology in the past decades, KOCKS clearly contributed to meet high availability, efficient production, fast dimension change and tightest tolerances to secure a rolling mills’ existence. The repeatability of tightest tolerances is an enormous challenge due to the constantly changing basic conditions of a mill. The operator needs to precisely adapt the process parameters reacting to smaller lot sizes made of different material grades with partly strongly varying spreading and shrinkage behavior or yield strengths. It is KOCKS' objective to meet this challenge by an automated tool, the Size Control Systems SCS®, thus lifting the quality assurance of long products to a new level.

Abstract:

A further closure of the water circuit in paper mills with a relative high optimization of their water network is limited by the increase of contamination in the water and runnability problems of the paper machine. Therefore, new strategies for saving water must be focussed on the treatment of final effluents of the paper mill, aiming to obtain high quality water that may replace fresh water use in some applications. An appropriate treatment train performed at pilot scale, consisting on a previous clarification stage followed by anaerobic and aerobic treatments, ultrafiltration, and reverse osmosis, made possible producing the highest water quality from the final effluent of the mill. Anaerobic pre-treatment showed very good performance assisting the aerobic stage on removing organics and sulphates, besides it produced enough biogas for being considered as cost-effective. Permeate recovery depended on the silica content of the paper mill effluent, and it was limited to a 50–60%. The reject of the membranes fully met the legislation requirements imposed to effluents arriving to municipal wastewater treatment plants.

Abstract:

Super think sheet are high value added products among other cold rolled products. The production process and production equipment are difficult to develop and not easy to be understood and mastered. For a long time, they have been in monopoly of other countries. To address the problems existing in conventional temper mill for super thin strip rolling, three main technologies are applied to the new design and to the manufacturing. They are: a. technology for stabilizing product performance; b. technology for surface quality control and c. technology for improving yield and productivity of the line. These technologies successfully eliminate the difficulties of stabilizing mild steel performance and improve the surface quality and line productivity. Significantly, a serious of technical problems for conventional super thin strip temper mill are solved through indigenized technologies.

Abstract:

The determination of the optimal operational mode of drum mills can be assessed by different criteria. The most important of them can be formulated as follows: “To be specified and established the values of the mill operational parameters regarding to which it is possible to be provided the user’s expected performance at the required quality of the final product and the same to be achieved at minimal energy consumption”. For the fulfillment of this condition, there has to be determined the laws of productivity variation, the final product quality and the energy consumption in function of the adequately chosen representative control parameters of the mill. There are obtained mathematical models, describing the most important technological parameters of the machine and are made conclusions about the factors influencing on them.
