    Aug 30 the wear of drop steel ball is related to its impact force the wear of grinding steel balls is related to the surface area of steel balls in general the steel ball in the grinder has both impact and abrasion effects so the wear is proportional to the n power of the diameter of the steel ball and the value of n is between 2 and

    How To Estimate The Wear Rate For Ball Mill

    Dec 08 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 more simply and quite adequate

    If the peripheral speed of the mill is too great the mill begins to act like a centrifuge and the balls do not fall back into the center of the mill but stay on the perimeter the point where the mill becomes a centrifuge is called the critical speed and ball mills usually operate at 65 to 75 of the critical
