Abstract The subject of the proposed study is aimed at studying the process of grinding barking waste. The main tasks of experimental research are to establish general patterns linking the energy intensity of grinding of debarking waste with the degree of grinding and to estimate the energy intensity of the grinding operation of barking waste in prepara-tion for utilization. The article presents the results of experiments on crushing waste from spruce and pine, performed with the Erdwich M600 / 1-400 industrial choppers.

Abstract:

The analysis of modern research shows that when evaluating the specific energy intensity of the abrasive processing process, one should pay attention not only to the indicators of grinding power and material removal rate, but also to the indicator of the wear of the abrasive tool, which we will show below for the grinding tool made of superhard materials. It is shown that the traditional method of estimating the specific energy capacity based on the ratio of the grinding power to the processing productivity does not provide an adequate solution, since with it the specific heat capacity of proc

Abstract The paper presents the issues related to the grinding process in the vibration mills with low vibration frequency. These mills are rated among devices with high energy of impacts with much wider potential of industrial use than the classic gravitation mills. In vibratory mills there is an unfavorable decrease in the intensity of the grinding process along with the increase in the chamber diameter, which makes it impossible to achieve high performance of such devices. One of the ways to reduce or eliminate this occurrence is to intensify the load movement inside the chamber – this is t

An analysis of the technological limitations of magnetite quartzite beneficiation illustrated the imperfections of the traditional classification by size. As an alternative to size classification, separation by the degree of magnetite grain liberation can be employed. Comparative analysis of the mineral phase properties of the magnetic separation feed and its magnetic product has confirmed that wet drum magnetic separators currently used for wet treatment of magnetite ores have a low selectivity of separation.

Straw has a high energy capacity, but it is not ideal for the operation of biogas plants, since it contains a large amount of nitrogen-free substances, and only 4-6% nitrogen and mineral salts, but if it is properly pretreated, it is possible to reduce the fermentation time and increase the biogas yield. The positive results of pretreatment of biological raw materials are a high degree of grinding and homogenization of raw materials; reduction of the biomass fermentation period; the release of natural enzymes that are biological catalysts for the fermentation of biomass; stabilization of biolo

AbstractThe present work focusses on the loss of resilience of torrefied wood as an indicator of its grindability. An impact device was developed to evaluate the mechanical behaviour of wood at high compression rates with a particular emphasis on the surface area of the particles produced. It allows the energy determination needed to produce particles without a traditional grinding test. Pine (Pinus pinaster) and oak (Quercus robur) were tested in radial (R) and tangential (T) directions and for various torrefaction intensities. With increasing heat intensity, the material becomes more fragile

The quality of sharpening of flat wood-cutting knives in a certain way affects the quality of the parts obtained. The sharpening process is carried out by a grinding carriage performing a rectilinear reciprocating motion relative to a fixed knife. When the massive carriage is reversed, free oscillations (transients) occur, whichleads to a violation of the straightness of the cutting edge of the knife, limited by the requirements of GOST. Reducing the vibration activity of the process and achieving the required quality of knife sharpening provides a constructive solution for reversing the movem

In recent years, interest in nanostructured materials has been growing due to the unique mechanical properties that distinguish them from traditional analogues. Planetary ball milling is one of the used method because of its simplicity, low cost and ability to produce large volumes. To reduce the adhesion of the powder to the balls and the grinding vials and to avoid cold welding of plastic metals in the grinding process, process control agents (PCA) are used. Under conditions of ball milling, organic PCA decompose and thus become sources of hydrogen and carbon for the materials being crushed.
