Mill (grinding) - Wikipedia

A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

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.

Development of a method to measure charges in tumbling mills

Common Methods to Measure Tumbling Mills Charges. The charge level of a mill can be described as the volume occupied by the grinding media (including empty spaces) as a fraction of the total volume available inside the equipment. Assuming this definition, other measurements may be taken considering the total.
