Due to the problems of the original crushing process in Sizhou Concentrator,such as com-plex process,low pre-screening efficiency,unbalanced medium and fine crushing processing capacity and coarser final product particle size,the feasibility of optimizing the crushing process to"two stages and one closed circuit"is analyzed based on the indicators of the raw crushing process,such as equipment handling capacity,equipment load rate,crushing efficiency,screening efficiency and product quality.The research results show that using the"two-stage and closed-circuit"new crushing process,the crushing system pro-cessing capacity increased by 127.02 t/h,the load rate of medium and fine crushing crusher increased by 27.67 and 12.84 percentage points,the system cycle load increased by 28.27 percentage points,and the fi-nal product-5 mm content increased by 3.88 percentage points.The newly developed ore crushing process shorens the ore crushing process,reduces the number of equipment,improves the ore crushing efficiency and improves the product quality,which is of great significance for improving social and economic benefits and building green mines.
