CHINA MINE ENGINEERING

Based on the problems of old equipment, small type, large quantities, high maintenance costs, etc, technical transformation of SAG mill process was carried out on the pyrite mine in Guangdong. Simulation basic data was confirmed according to the research on ore properties and experiment results of crushing and grinding. One ?8.53m×4.27m SAG mill (5400kW) and one ? 5.8m×9.5m ball mill (5400kW) were selected according to JKSimMet simulation. Simulation on three different operation conditions demonstrated that different ore with different hardness and fineness could be treated, and the fineness of grinding products could meet design requirement. This study will provide technical support for the equipment calculation and future production adjustment.
