Aug 11, 2015 · Ball mill preventive maintenance (PM) It is a frequency work to maintain and repair ball mills, AG mills and SAG mills. The maintenance work influences the rotational speed and service life of ball mills. In order to reduce downtime of ball mill, regular examination and timely replacement of the parts should be done.
What is a ball mill and how does it function Answers . Ball Mill is widely used in metal and nonmetal mines, building materials and other industrial sectors of various minerals and rock grinding. Chat Now
Vertical spindle roller mill. Similar to the ring and ball mill, the vertical spindle roller mill uses large "tires" to crush the coal. These mills are usually found in utility plants. Raw coal is gravityfed through a central feed pipe to the grinding table where it flows outwardly by centrifugal action and is ground between the rollers and table.
