Applications for mining industry. 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.
The grinding charge in a ball mill consist of cast or forged steel balls. These balls are fed together with the feed and consequently ball mills can be in operation for months without stopping. The ball size is often in the diameter range of 20 75 mm. The biggest size is chosen when the mill is used as a primary grinding mill.
In the grinding process of planetary ball mill, the grinding ball plays a vital role. The ball mill drives the material and the grinding ball to run, and the moving energy of the grinding ball continuously acts on the material, so that the material is crushed or mixed to an ideal state.
