The vertical stirred mill is vertically installed, and gravity works in the grinding process. With the advantages of high grinding efficiency and less area occupation, it is widely used in the regrinding, fine grinding, and ultrafine grinding process of such metal mines as iron ore, copper ore, leadzinc, and such nonmetallic mineral industries as calcium carbonate, kaolin, and graphite.

The current procedure to compensate the screw liner wear on industrial vertical stirred mills is to keep electrical power draw constant by increasing mill filling during the liner lifecycle. The basic idea is to activate the upper parts of the mill in order to maintain a constant grinding power while the screw liner wear decreases media motion ...
