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.During wet and dry conical lattice calcite grinder milling plant machine wet grinding, materials are taken away by water flow; During dry grinding, the material is taken away by air flow. Ultrafine mill features large double row self-aligning roller bearings instead of sliding bearings.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.
