Vibration cone crusher for disintegration of solid materials

Abstract

Traditionally, during the disintegration of natural and technogenic mineral raw materials, as well as other materials, crushing machines with a kinematic drive of working bodies are used.However, such a drive has a low degree of crushing and high energy costs.In addition, if we are talking about the disintegration of natural and technogenic raw materials containing mineral aggregates, then in these machines it is practically impossible to ensure sufficient selectivity of the liberation.The aim of the research is to develop an energy-efficient method of destroying various materials with the implementation of the process of selective liberation of minerals with the simplest design of the machine (without rigid kinematic connections of the working bodies, without oil stations and special slide bearings). In the course of the research, a mathematical analysis of the dynamics of the vibration crusher was carried out to determine the required mechanical parameters, which made it possible to adjust the body and the crushing cone of the machine to high-frequency synchronous-antiphase oscillations in the operating frequency range.As a result of the conducted experimental tests, the reliability of theoretical studies was confirmed and the dependences of technological indicators on the controlled parameters of the machine were determined in the operating frequency range.
