Grinding media sorting and balls Magotteaux
Grinding media. Grinding balls are only one type of grinding media. Grinding media are the means used to crush or grind material (cement, mineral, ) in a mill. Grinding media sorting is performed when the ball load wears out. New grinding balls are then added or full reload is carried out to keep optimum filling degree
