Working Principle

   Electrical machine drive the main spindle to rotate through triangle belt. Some rotor disks which fixed and stringed with the spindle rotate. There are many countershafts on rotor disk with some rollers on it. Under the friction  action of materials, rollers not only ratation but also revolution. Materials are fed from the upper Hopper, and then swung to the side of lining through dividing plate, entered into the mill intracavity formed by rotor disk and lining.,and it was grinded into powders by rollers repeating rolling and discharged from bottom of the equipment under gravity.

Applied range and features

This ZHM column mill can be widely used for grinding various kinds of low hardness materials  in building materials, chemical and metallurgical industries, such as limestone, lime, dolomite, inorganic salts, organic polymers, coal and other materials.Low electricity consumption,high grinding efficiency, reasonable grade distribution.Compact construction, small volume and great production capacity.High abrasion-resistan material, long working life, easy operation and maintainance.
