NOUFERROUS METALLURGICAL EQUIPMENT

In order to solve the problems of outdated equipment, small specifications, large quantity, difficult production and maintenance, high maintenance costs, low labor productivity and high operating costs in the crushing and grinding system of a certain pyrite beneficiation plant in Guangdong, technical transformation and optimization research on the crushing and grinding system were carried out. Through the study of regular crushing-ball mill grinding, HPGR-ball mill grinding and SAG mill-ball mill, the optimal implementation plan is determined to be SAG mill-ball mill process, namely coarse crushing-SAG mill-ball milling (CSAB). After adopting this crushing and grinding process, the unit ore cost is reduced by 11.96 yuan/t. At the same time, it can significantly improve the working environment, enhance safety level, reduce staffing, significantly increase labor productivity, reduce maintenance workload, better ensure the stability of enterprise production, and create better economic and social benefits.
