“…All these actions lead to protecting the natural environment. The variety of technological environments found in food processing machinery and equipment means that components of moving nodes are subject to extremely rapid wear under the simultaneous effects of friction, thermal, and corrosive forcing [ 4 , 5 , 6 , 7 , 8 , 9 ]. Due to the variability in operating conditions, the wear of equipment components varies.…”

Providing high-quality machinery and equipment in technical terms is an activity aimed primarily at ensuring the high reliability of nodes. Reliability of machinery and equipment is mainly characterized by resistance to destructive processes. Mutual displacement of parts causes destructive friction phenomena, the intensity of which can be intensified by the interaction of specific technological environments. The article presents the results of research on ring-on-ring samples made of C45 steel in the non-heat-treated state, which were subjected to mechanical, corrosive, and abrasive wear and various combinations of them. The main purpose of the study was to determine the wear that results from the action of destructive friction and corrosive processes with the presence of abrasive material in the tribological node. The results supplement the knowledge of material wear under the simultaneous action of several destructive factors. Based on the study, it was noticed that the sum component of mechanical–abrasive–corrosive interactions is about 40–50% of the total wear. Mass loss resulting from simultaneous mechanical and abrasive interactions is equal about one-third of the total wear. In addition, it was observed that the effects of the interactions of friction (mechanical), corrosive and abrasive excitations are synergistic in nature, which lead to increases in the total wear of the tested samples made of steel. The results of the research are of practical importance and allow for wear-optimal selection of material in the friction node of modern machinery and equipment.

Livestock farming, as one of the main sectors of the agro-industrial cluster, cannot do without good quality forage. For the best absorption of feed, all the nutrients that make up its composition should be given to the animals in a milled form. Hammer mills are among the most compact machines for milling. The grinding of grain forages is a rather energy-intensive process. One of the variants for solving the power intensiveness problem can be the application of a a hammer crusher with periodic fluctuations in the angular speed in the rotation of the the working body. That is accompanied by the appearance of additional external stimulating force - vibration on the elements of a hammer crusher. In the article the question of vibration occurrence at non-uniform rotation of a crusher working body drive pulleys is considered. And such parameters as vibration acceleration, vibration displacement, and vibration velocity in three different axes are considered. In order to optimise the vibration parameters, experiments were carried out on units of different designs with different centre of rotation offset (2 mm). At this uneven rotation speed of 1800 min-1, the vibration velocity on the X-axis increased by 546% and 200%, depending on the machine design. The vibration displacement on the same axis, even at 450 min−1, increased by 442%. Based on these results, we examined the prerequisites for the investigated hammer crusher drive design, which is expected to improve the separation and evacuation process of the crushed product from the crushing chamber, and have an overall positive impact on the crushing process.
