Grinding Mill Design & Ball Mill Manufacturer
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.

Marked Ball Wear Test
The galvanic reaction tended to protect the chrome balls at the expense of the forged balls. There weren't enough chrome balls in the charge to significantly affect the forged ball wear rate. Once we converted a mill to chrome balls we found that the consumption rate was significantly higher than the marked ball tests predicted.
