How to Reduce the Wear of Steel Ball in the Ball Mill Machine?

How to Reduce the Wear of Steel Ball in the Ball Mill Machine? In the grinding operation, the consumption of steel ball is very large, which is about 10 times more than the loss of ball mill liner. In order to make up for the loss of steel ball and keep the size of the steel ball unchanged in the ball mill machine, it is necessary to add the steel ball regularly according to a certain ratio ...

Tool Wear: Meaning, Types and Causes | Metal Cutting

Crater wear, flank wear (or wear land formation) and chipping of cutting edge affect performance of the cutting tool in various ways.

Rod mills, how they function - Mine Engineer.Com

Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed. Rod mills usually require greater .
