Grinding balls for ball mill use are used in many areas of mining and industry to pulverise and grind. Grinding balls for mining are generally used to break down secondary materials such as rock, cement and stone during the extraction of ores and metals. AISI steel grinding balls for ball mill applications typically have a tolerance of±0.05/±0.10 and a density of 7.70 to 7.95.
