Oct 12, 2017· Ball mill is a fine grinder. A horizontal or vertical rotating cylinder which is filled partially with the balls of ceramics, small rocks and balls made from stainless steel. The ball charge of a SAG mill is about 29% to 30%. By friction and influence of tumbling balls inside rotating cylinder grinds the raw material to the required fineness.
Pulverizer Wikipedia. With adequate mill grinding capacity, a vertical mill equipped with a static classifier is capable of producing a coal fineness up to % or higher . 50 mesh and 80% or higher 200 mesh, while one equipped with a dynamic classifier produces coal fineness levels of 100 mesh and 95% 200 mesh, or better..
