Grinding Media Wear Rate Calculation in Ball Mill. The primary focus is on grinding balls, but the same analysis can be applied to grinding rods. The wear law for grinding media is discussed, and the relationship between marked ball wear test data and production wear rates is demonstrated.
How to Calculate Gear Pitch. The diametral pitch of a gear describes how densely its teeth are set around it. The pitch is the ratio between the number of teeth and the gear's size, and engineers always express it as a whole number. This value is important for further calculations involving the .
Dec 08, 2009· Re: how to estimate the wear rate for Ball mill. Hey; Ball wear can be measured by weighing an entire charge before and after grinding a known tonnage of materials. With new balls sample of given size can be weighed before and after grinding a given tonnage and, assuming uniform wear per unit of ball surface, the total charge wear can be estimated.

Grinding Media Wear Rate Calculation in Ball Mill. In any mill, the rate at which the surface of any ball decreases is proportional to its surface. Since the rate at which a ball loses weight varies as the work done upon it in the mill, it follows that the work done in wearing (or crushing) the ball varies as the weight of the ball.
