Abstract: Proposals for improving the efficiency of operation of cone crushers are considered. It is shown that the efficiency of operation of cone crushers is directly related to the physical and mechanical properties of the crushed material, their influence on the profile of the crushing chamber of cone crushers, and the influence of the gap of the eccentric assembly. This work is devoted to the problem of the need for mandatory pre-project studies. The analysis showed the possibility of improving the workflow due to: exclusion of material pressing in some areas of the crushing chamber, increasing the throughput of the crushing chambers, and controlling the crushing process. As a conclusion, a number of recommendations are proposed for improving the workflow in cone crushers for fine crushing. Recommendations should take into account the location of the crusher in the technological chain of the crushing and screening plant, the assessment of the physical and mechanical properties of the crushed materials (allowing to regulate the operating conditions of the crushers), the assessment of the accuracy of manufacturing parts and assemblies of the crusher that form the crushing chamber, which provides the design parameters of the crushing process. The results of experimental data on the determination of physical and mechanical properties and crushability characteristics of materials from the Bazhenov deposit, Khust ore and Mezhdurechensk shale are presented. An example of a designed armor of a fixed cone with increased technological performance for specific operating conditions is shown. Recommendations are given for the structural improvement of the crusher to implement the necessary parameters of the operating mode and reliability of the machine
