Ultrafine mill is a common grinding equipment in concentrator. Compared with other calcite grinder milling plant machine equipment, it can save energy and reduce consumption by 30%. For fine-grained mineral processing, it can increase the processing capacity by 15 ~ 20% compared with other calcite grinder milling plant machine equipment.

In the cylinder, the materials are crushed due to the throwing impact and self grinding of the steel ball and the ore itself. Due to the continuous feeding of materials, the pressure causes the materials in the cylinder to move from the feeding end to the discharge end, and the materials reaching the particle size of finished products are discharged from the discharge end of the cylinder.

Friction is greatly reduced, easy to start and significant energy saving; The discharge end adopts conical design, and the materials and steel balls at the discharge end are graded, which not only increases the volume, but also forces the cone closer to the discharge port and the smaller the diameter of the steel ball, increasing the effect of repeated grinding;
