In order to improve the grinding equipment to increase the efficiency of fine grinding, an analysis of the state of fine grinding of materials has been carried out, and the use of impact for fine grinding has been substantiated. One of the possible solutions to the problem of intensifying the process of fine grinding of materials by impact is presented, an impact grinder with a new work organization scheme and increased energy stress has been developed. An empirical and theoretical model is proposed that relates the output and input parameters of the impact grinding process. The results of comparative experimental studies of the grinding process by impact according to the standard and according to the new scheme of work organization are presented, proving the efficiency and effectiveness of the grinder with the new scheme of work organization. New design schemes of impact grinders with counter impact on the material are presented. New information has been obtained about one of the ways to increase the efficiency of the fine grinding process by impact. The results of the work are the basis for further research of fine grinding processes by impact, development and improvement of processes and equipment for fine grinding.
