Principles of Ball Mill Grinding
When grinding enamel frit, wear to the porcelain balls is quite excessive because to the abrasive nature of the frit. Consequently, many operators have been able to closely determine the ball wear per batch and, when a batch of frit is loaded for grinding, a quantity of new balls is added equaling the weight lost during the previous grind.
