Ball Mill | PPT
The document discusses the ball mill, which is a type of grinder used to grind materials into fine powder. It works on the principle of impact and attrition, where balls drop from near the top of the shell as it rotates to grind materials placed inside. A ball mill consists of a hollow cylindrical shell that rotates about its axis, with balls ...
Trunnion Bearing Assembly Ball Mill & Rod Mill
The first part of the mill that we will look at is the TRUNNION BEARING. This is a HYDROSTATIC BEARING which is a slow moving bearing that carries a heavy load. Usually it is constructed from Babbitt's metal.
