In addition, the slurry level of the slurry in the mill is lower, and the buffering effect on the falling of the steel ball is achieved. Therefore, the productivity of the lattice ball mill is 10%15% larger than that of the overflow ball mill of the same specification, and the grinding efficiency is also higher than that. The latter is high.
