2.More crushing and less grinding, reducing the feeding particle size of ball mill. The larger feeding particle size is, the greater the work done by the ball mill on the ore, which impacts the grinding efficiency. To reach the eligible grinding fineness, the workload must increase. The energy consumption is also increasing.
A 62.5-percent solids discharge from the rod mill is sized in a spiral classifier operating in closed circuit with a ball mill. The sands are reground in the ball mill, and the pulp containing 80-percent, minus 150 mesh is pumped to a conditioner where 0.2 pound of KAX and 0.36 pound of MIBC per ton of slag are added.
The parameters used in the ball mill process are relatively large, however there are several parameters that have a significant effect on the reduction grain size produced. This experiment was designed using the Taguchi method to find the optimum parameters in the production process of mircoparticles silica sand tailing.
