mill,how we can measure ball mill balls wear rate

There are quite a few types of attritors; we can categorize them as dry grind attritors wet grind attritors regular speed attritors and high speed attritors a useful and simple equation describing the grinding momentum is m x v (mass x velocity) which enables us to see how the attritor fits into the family of mills for example ball mills use

Iv ball mills ball mills are one of the more common mills and use a closed cylindrical container that is rotated horizontally on its axis so that the media cascades a typical ball mill has an ld ratio of 15:1 ball mills are filled with spheres or other shapes made of steel or ceramics; or with pebbles made of flint (or of an ore being ground)

We can provide quality down to grade 25 on special order to accommodate a larger flow rate the diameter of the ball must increase the volume and therefore the mass of a ball varies as four times pi times the radius cubed over three 4 314 (r3) 3 so any increase in the ball diameter has a dramatic affect on the mass of the

As a result the inherent wear rate of martensitic balls increases slightly at the ball becomes smaller therefore for a given ball mill with a constant wear law the resultant seasoned 76 mm martensitic ball chart should contain more large balls fewer small : balls and less surface area than a seasoned charge of 76 mm pearlitic carbon steel
