“…As shown in studies [1,2], subsequently and obviously from the elementary calculation, the energy balance of the shock process and the nature of the change in the energy consumed by the flyer from the spike were not confirmed experimentally. However, the experiments described in this work were performed incorrectly in the sense of choosing the frequency of natural vibrations of the system.…”

“…A number of studies [1][2][3][4][5][6][7] highlighted some of the technological aspects of impurity extraction in this type of a cleaner. A number of new problems were identified, the study of which became possible due to the use of modern means of experimental research and processing of its results.…”

The article describes a study of the dynamics of interacting between loosening roller spikes and particles of raw cotton as well as the conditions for the raw cotton particles' bundling. The process of movement of raw cotton particles was considered on the mesh surface of a fine impurity cleaner; a search was made for ways to intensify the process and to increase its stability. The conditions for imparting a rotational motion to the flyer were determined when the flyer was connected with the supplied layer of raw cotton. Turning the flyer against the axis will twist the fibre bundle that binds the particle to the rest of the cotton mass, and this is a prerequisite for the fibre to bundle. The value of the twist angle will depend on both the frictional force and the time of the force action, which together determine the energy spent on twisting. By piecewise linearization of the P(t) curve, the processes of shock loading and unloading of the flyer during interaction with the spike are described in good agreement with the experimental oscillograms of the process. The eccentric interaction of the spike with a particle of raw cotton was considered. The relationship of this interaction with the formation of soft defects in the fibre-bundles-was proven experimentally and theoretically. It is recommended to install spike rollers having a flat front face in the system of raw cotton pre-cleaning. The use of spikes of this shape of the front edge ensures a steady reduction in the number of bundles in the raw cotton fibre, which increases the quality of the fibre and reduces the amount of defects and impurities. As a result of the experimental and theoretical studies, data have been obtained to make it possible to organise the efficient operation of cleaning machines in the cotton ginning industry

“…(Afanasyev, 1983). In agriculture, the cylindrical drum grinders are mainly used for pressing and grinding the grains, pesticides and fertilizers that have hardened during storage (Rudovsky et al, 2019). For the first time, the grain grinding by pressing was investigated with dry grain pressing (Baldanov and Khusaev., 2002).…”

The conducted research is devoted to the study of the balance of forces affecting on the grain between cylindrical rolls of the small-size feed mincing unit used in farming enterprises. It is established that substantiation of design and process parameters of the feed mincing units, plotting the analytical dependences and solution of process tasks are among the most important factors in manufacture of various versions of the unit. Using the obtained analytical solutions increase the efficiency of the works performed in this field. Recently, in the countries where the grain is harvested using the two-phase method, it is performed during the milk maturity period by pressing with special grinding machines immediately in the field, adding the conserving agent, preserving, packing into polyethylene bags, and then storing tight during winter. It is proven that the production costs for such nutritive grain feed reduce by 30% in contrast to the usual method. The grain stored in such a way is taken out of the grain bags and used directly for feeding the animals. The research work aimed at substantiation of design and process parameters of the small-size, low energy-intensive units for feed oakum production functioning on the basis of the grinding method in the conditions of farming enterprise is of great relevance. The work purpose is to study the balance of forces affecting on the grain between cylindrical rolls of the small-size feed mincing unit.

The strength of spinning products formed by the wet finning method is determined by the adhesion forces that arise between the contacting fibers. To predict the strength of yarn and roving obtained in this way, it is necessary to know the number of fiber contacts in the cross section of the product. Studies of the distribution of fibers in the section of linen roving have been carried out and a method for determining the number of fiber contacts has been proposed. The initial data are digitized images of roving sections obtained using a digital microscope. After threshold processing of the image, the perimeters and areas of continuous sections occupied by fiber sections were calculated. The area of a single fiber is defined as the average area of the five smallest sections in the section. Based on the analysis of these data, a mathematical model of the dependence of the number of contacts between fibers on the perimeter of the section of the spinning product was constructed.
