Sustainable Mining and Metallurgy

Based on the production practice of intelligent grinding system of semi-automatic grinding process in a concentrator, the effect of important control parameters and operation conditions of semi-autogenous mill of intelligent grinding system were summarized and analyzed. Through the analysis of production practice data, it is found that the key control parameters of the intelligent grinding system are semi-autogenous mill speed, feeding size and grinding concentration. The speed of semi-autogenous mill is the most sensitive parameter to the control of intelligent grinding system, and the regulation effect is the most significant. It can quickly adjust the operation state of grinding system. The feeding particle size takes the second place, which can play a short-term adjustment role;the grinding concentration has the weakest sensitivity and can achieve fine adjustment. Through the collaborative control of the above key parameters, the processing capacity of the grinding system can be maximized, and the product size can be adjusted and controlled.
