    Therefore, we usually adopt the cement roller press to replace the fine crushing and coarse grinding role of the ball mill. This increases the output of the ball mill system by 30-50%, and 20-35% of the extruded materials are smaller than 0.08mm, 65-85% are smaller than 2mm. Besides, a large number of cracks will be produced on all extruded materials, which will greatly reduce the energy
