value of rittingers constant for ball mill price

BALL MILLS 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.
