Abstract:Through the research of the structure and process of HPGR, this paper demonstrated the application prospect of HPGR in the non-ferrous mineral processing industry. The results of ultrafine crushing and grinding test of HPGR indicate that the non-ferrous ore is greatly improved by the new-type HPGR after ultra-fine crushing, which can greatly improve the processing capacity of the ball mill and effectively reduce the Bond work index. After the industrial production practice verified, the two concentration plants upgraded and transformed the grinding system through HPGR, the particle size (F95) of the ball mill feed reduces from less than 12 mm to less than 5 mm, and the Bond work indexes of ball mill feed reduce from 13.78 and 11.64 kW？h/t to 11.84 and 9.94 kW？h/t, respectively. The overall processing capacity of the concentration plants increases by about 67%.
