| Abstract: | According to the principle of more crushing and less grinding, appropriately reducing feeding size of the ball mill was conductive to reducing the energy consumption and steel consumption of the grinding operation as well as improving the throughput of the crushing and grinding system. Based on the theory of crushing and grinding energy consumption, the paper narrated the influence of reducing the feeding size on the grinding efficiency, and discussed the methods of calculating the optimal feeding size of the ball mill. In combination with production practice in concentrators, it also introduced the technical measures to reduce the feeding size of the ball mill. |
