Abstract

The tube mill has a shell with abrasion-resistant linings selected to suit the behaviour of two different materials processed simultaneously. The two chambers are separated by a gas tight partition. To each side of the partition at some distance perforated partitions are provided creating discharge chambers with several discharge openings. The discharge chambers are stationary and surround the rotating mill which is seated by two neck parts serving as material charge openings served by chutes. The ground material leaves the mill through perforated partitions and discharge openings into the discharge chambers and from there through sluice mechanisms into the open, while gases and dust are exhausted through connections with airtight partition at the top of the discharge chamber.
