Increasing the Efficiency of a Cone Crusher by Optimizing the Design of the Eccentric Unit

This article studies the influence of the design features of the eccentric unit on the performance of a cone crusher, the purpose of which is to increase the productivity of the cone crusher by changing the design of the eccentric unit of the cone crusher. The object of study in this article is the existing designs of the eccentric unit, the limitations of their functionality. The article presents an analysis of the design features of the eccentric unit of a cone crusher with a cantilever shaft and its disadvantages. Based on the analysis, a prototype of an improved design of the eccentric unit was developed, which allows for increased productivity and reduced energy consumption of the cone crusher due to the use of support and adjusting disks. The rotation speed of the crushing cone is adjusted by turning the adjusting disk at a certain angle. The main design schemes of the developed eccentric unit, its model, operating principle and advantages are presented. In the course of theoretical studies, the dependence of the influence of the cone rotation speed on the performance of the cone crusher was established. To ensure efficient operation of the cone crusher with the improved design of the eccentric unit, it is necessary to rotate the adjustment disk by 90 degrees and ensure maximum throughput of the outlet. The use of this invention will increase production volumes and reduce energy costs by reducing the rotation frequency of the cone. The results of this study allow us to conclude that it is necessary to use the developed design of the eccentric unit in the production of industrial materials.
