Abstract:

Effects of triethanolamine grinding aids on the angle of repose, fineness, particle morphology and particle size distribution of cement are studied, and the action mechanism of grinding aids is discussed by surface tension and Zeta potential. The results show that the powder fluidity and particle circularity of cement are improved and the particle size and grinding time of cement are effectively reduced by grinding aids. And Grinding aids improve the particles content in the range of 3-32μm particle size by 6.63% and promote destruction of the chemical bonds and lattice distortion of cement mineral during the grinding process. The dispersion grinding mechanism of grinding aids is that they can reduce the surface free energy of powder to prevent fine particles from closing each other and shield or neutralize the particles surface partial charge to prevent facture surface from healing and promoting the cracks to extend easily.

Abstract:

An extension of the classical Obriemoff experiments has been set up to measure the fracture energy of mica. This experimental system will be entirely independent of slurry rheology. CTAB (Cetyl Trimethyl Ammonium Bromide), sodium tripolyphosphate, sodium hexametaphosphate, and tri-sodium citrate are used as grinding aids in this study and the fracture energy has been measured for mica in air, water, and water with the addition of various concentrations of these grinding aids. The results show that the fracture energy of mica in water is about half of what it is in air. Grinding aids are shown to reduce the fracture energy of mica, but not dramatically. Addition of grinding aids reduces the fracture energy by a further 10-20%, with tri-sodium citrate appearing to be the most effective. For each grinding aid there appears to be an optimal concentration, typically around 10 mmol. An experiment is also done with sodium chloride at a range of concentrations to investigate the mechanism of these grinding aids, but no reduction in fracture energy (compared to water) was observed, hence the molecular-level mechanism of action of these grinding aids remains unclear. The effect of solution pH values on the fracture energy are also investigated using tri-sodium citrate and sodium chloride. The results show that the solution pH value may effect on the fracture energy of mica. So, in practice, both concentration and pH value of solution are important for getting better grinding results.

Abstract:

The application of chemical additives, known as grinding aids (GA), dates back to 1930 in the cement industry. As opposed to the cement industry, where the use of GAs is on the final processing step, it could be one of the first process steps in ore beneficiation. A few investigations addressed the GA applications in ore dressing; therefore, further studies are required to better understand the GA effects on the product properties and downstream separation processes. This thesis undertakes a comparative study on the dry grinding of magnetite and the resulting product characteristics with and without GAs. The main aim is to reduce energy consumption and to address some of the challenges associated with dry processing. The effects of GAs on the dry batch ball milling of magnetite were examined to analyze the energy consumption (Ec), particle size distribution, flow properties, bulk properties, surface morphology, particle fineness, and surface chemistry of products. Their effects on the ground product were systematically explored by sieve analysis, powder rheology, BET surface measurements, optical microscopy analysis, and zeta potential measurements. Compared with the absence of GAs, the dry grinding efficiency of magnetite increased after using GAs; however, an optimal dosage exists based on the GA type. Among GAs which considered in this investigation (Zalta™ GR20-587 (Commercial GA) and Zalta™ VM1122 (Commercial viscosity aid) as well as sodium hydroxide), Zalta™ VM1122, a polysaccharide-based additive, was the most effective GA where by using this GA; the Ec decreased by 31.1% from 18.0 to 12.4 kWh/t. The PSD became narrower and finer (P80 decreasing from 181 to 142 µm), and the proportion of the particles (38–150 µm) increased from 52.5 to 58.3%. In general, the results reveal that at sufficient GA dosages, they reduce the average particle size, increase the specific surface area, and narrow the particle size distribution. However, an excessive amount of GAs could be detrimental to the grinding performance. Further studies on powder rheology indicated that the used GAs resulted in improved material flowability compared to grinding without additives (in the examined dosage range). The rheology measurements by the FT4 Powder Rheometer showed strong linear correlations between basic flow energy, specific energy, and the resulting work index when GAs was considered for grinding. There was a strong correlation between the grinding parameters and flow parameters (r > 0.93). These results confirmed the effect of GA on ground particles' flowability. Zalta™ VM1122 showed the best performance with 38.8% reduction of basic flow energy, 20.4 % reduction of specific energy, 24.6% reduction of aerated basic flow energy, and 38.3% reduction of aerated energy. The present investigation showed that the predominant mechanism of GAs is based on the alteration of rheological properties. Further investigation on the surface properties showed that using GAs could increase the surface roughness, which is beneficial for downstream processes such as froth flotation. Zalta™ VM1122 resulted in increased surface roughness and minimum microstructural defects from the optical microscope images. Furthermore, Zalta™ VM1122 (non-ionic) resulted in similar zeta potentials and pH values for the product compared to experiments without GA. These comparable product properties are advantageous as they minimize any potential negative effects on all possible downstream processes.

Abstract:

Scholarship on urban culture and the senses has traditionally focused on the study of literature and the visual arts. Recent decades have seen a surge of interest in the effects of sound on the urban space and its population. These studies analyze how sound generates identities that are often fragmentary and mutually conflicting. They have also explored the rise of campaigns against the negative effects of noise on the nerves and health of the population. However, little research has been carried out on the impact of sound and music in areas of broader social and political concern, such as social aid, hygiene, and social control. Based on a detailed study of Madrid from the 1850s to the 1930s, this book argues that sound and music have played a key role in structuring the transition to modernity by helping to negotiate social attitudes and legal responses to problems such as poverty, insalubrity, and crime. Attempts to control the social groups that own unwanted musical practices such as organ-grinding and flamenco performances in taverns raised awareness about public hygiene, alcoholism, and crime and triggered legal reform in these areas. In addition to marginalizing and persecuting these musical practices, the authorities and the media used workhouse bands as instruments of social control to spread “aural hygiene” across the city and wipe out unwanted musical practices.

Abstract:

This chapter aims to optimize centreless grinding conditions using the Taguchi method for minimizing surface roughness. The grinding operation has been performed according to the L9 orthogonal array in a centreless grinding process. The centreless grinding experiments are carried out on the crane-hook pin of C40 steel. The analysis of variance (ANOVA) and computation of signal to noise (S/N) ratio are adopted to determine the influence of grinding parameters (depth of cut [µm], regulating wheel speed [rpm], and coolant valve opening) on surface roughness. The depth of cut (µm) is found to be the most significant among the grinding parameters on the surface roughness. The signal to noise (S/N) ratio was calculated based on smaller the best criteria. The lower level of depth of cut, medium level of regulating wheel speed, and higher-level coolant valve opening is found to be optimal grinding condition according to the mean response and signal to noise (S/N) ratio.

Abstract:

Hard turning and grinding are competitive processes in many cases for manufacturing various mechanical products. Product performance is highly dependent on the process induced residual stresses. However, there exist some inconsistence regarding the true residual stress profiles generated by hard turning and grinding with and without the presence of a white layer. This study aims to clarify the pressing issues via an extensive residual stress measurement for five surface types: hard turned fresh (HTF), hard turned with a white layer (HTWL), ground fresh (GF), ground with a white layer (GWL), and as heat treated. The x-ray diffraction data revealed distinct differences in the residual stress profiles between the turned and ground surfaces. Specifically, the key findings are: (i) HTF surfaces generate a “hook” shaped residual stress profile characterized by surface compressive residual stress and maximum compressive residual stress in the subsurface, while GF surfaces only generate maximum compressive residual stress at the surface; (ii) HTWL surfaces generate a high tensile stress in the white layer, but has highly compressive residual stress in the deeper subsurface than the HTF surface; (iii) GWL surfaces only shift the residual stress to more tensile but does not affect the basic shape of the profile; (iv) Tensile residual stress in the HTWL surface is higher than that for the GWL one. However, the residual stress for the ground white layer does not become compressive and remains tensile in the subsurface; (v) Elliptical curve fitting is necessary for measuring residual stress for the HTWL surface due to the presence of shear stress induced severe Ψ splitting; (vi) Residual stresses by grinding show more scattering than those by hard turning; and (vii) Machining is the deterministic factor for the resulting residual stress magnitudes and profiles compared with the minor influence of initial residual stress by heat treatment.

Abstract:

One of the key issues facing rail maintenance crews today is the successful identification and removal of rail corrugations (a sinusoidal, longitudinal rail surface deformation). Typically, rail corrugations are identified through visual inspection (which look for regular surface patterns) or audio methods (which listen for high frequency noise). Once identified, removal is accomplished through rail grinding and consists of running standard “peak-and-plow” grind pattern(s), whereby the corners of the rail are angled upwards to peak the rail, then the top of the rail is ground down (plowed) by placing numerous stones around the top of the rail. “Peak-and-plow” corrugation removal can require multiple passes depending upon the depth of the measured corrugation as well as the type of grinder (available horsepower) and the number of stones present on the grinder being utilized. The above methodology is typically applied whenever corrugation removal is required and since the grind patterns are static, significant extraneous metal removal can occur both during corrugation removal and during rail profiling. An integrated system has been developed to identify and aid in the removal of rail corrugations. To assist in the detection and understanding of the severity of corrugations in the rail, a bogie frame mounted, accelerometer based measurement system was developed. The measured accelerations are filtered and transformed into displacement measurements which can be further processed to understand the primary wavelength and amplitude of the corrugations. These values can then be fed into specialized grinder control software which makes decisions on how to proceed with grinding; be it to remove corrugations then establish profile, only reestablish profile, or do nothing. Note that grinding may still be required to repair the rail surface due to other deformation such as rolling contact fatigue, shelling, spalling, etc. If corrugation removal grinding is required, the specialized software will create (in real-time) dynamic “peak-and-plow” grind patterns utilizing calibrated metal removal equations which estimate the amount of material one grinding stone can remove, based on the instantaneous radius of the rail, grinding motor horsepower, grinder speed, etc. The site specific, dynamic corrugation removal pattern contains calculated motor powers and orientations (angles) which will remove metal from the rails in such a way to both minimize metal removal required to eliminate the corrugations and minimize metal removal when establishing the desired post-grind rail profile. This paper explores recent developments in the identification and subsequent managed removal of rail corrugations with an end goal of the reestablishment of rail profile with minimal metal removal and maximum preservation of rail life. The principal behind the corrugation identification system is described with supporting experimental evidence. Also presented in this paper are the basis behind dynamic corrugation removal, modeling results of applying a dynamic “peak-and-plow” pattern, and a comparative study describing the simulated post-grind outcomes of applying dynamic corrugation removal versus applying traditional methods.

Abstract:

Industrial robots are flexible and cost-efficient tools for a multitude of applications such as, polishing, grinding, deburring, and welding. However, their utilization in machining tasks is currently limited due to insufficient position accuracy. This study aims to answer the research question: ‘Does including low frequency vibrations (mode coupling chatter) in tool path computation improve accuracy?’ For this purpose, the current paper focuses on setting-up a robust and flexible simulation framework. The framework implements a predictive cutting force method into a multibody dynamic (MBD) model of an industrial robot. The framework is structured in an extendable fashion for future research tasks. Future work will include mode coupling chatter into the MBD model to help mitigate the effects of chatter in robotic machining process, which in turn will increase tool-path accuracy.

Abstract:

Abstract In this paper, we investigate four methods that yield mathematical measures to analyze the precision of surfaces of manufactured parts. These four methods, namely the autocorrelation function, the Fourier spectrum, the Karhunen-Loève expansion, and a fractal-wavelet representation, are applied to surfaces produced from grinding processes. The first two methods are standard methods used in the surface analysis literature for qualitative signal characterization. The Karhunen-Loève expansion method, used in various signal processing applications, has never been applied to the field of surface characterization and representation. The fractal-wavelet representation has been previously proposed by the authors; its suitability to generate characteristic measures is investigated in this paper. The existence of characteristic measures of surface precision should aid designers in choosing process and design parameters and in comparing the precision between competing machining processes. The use of such measures is essential in taking a forward step towards integrating the fields of design and manufacturing.
