wear and tear test method for grinding balls

wear and tear test method for grinding balls

The mean abrasion rate of type J and K alloyed white cast iron balls was 0.43 mm³/m, or about half that of the better steel balls. Discussion. Although the true wear test of a grinding ball is its life in a real ball mill, the laboratory tests of impact and abrasion may serve as a guide to expected ball life.
