Grinding Balls Rods - 911 Metallurgist

20-10-2016  Grinding Balls. Steel balls ranging from ¾ to 5 in. in diameter are used. Rods range from 1½ to 4 in. in diameter and should be 3 to 4 in. shorter than the inside mill length. Tube mills are usually fed balls smaller than 2 in., whereas 4- or 5-in. balls are more commonly used for ball-mill grinding.

Steel Balls for Grinding • Sidenor

06-10-2016  Steel balls for grinding are produced in a range of 60-100mm diameter. They are used in ore grinding mills, such as SAG (Semi Autogenous Grinding) mills when it is for initial grinding or ball mills for regrinding. The most common applications of these steel balls are in gold, copper, iron, zinc, nickel and silver mining.

Chrome Balls VS Steel Balls - Grinding Classification ...

I think in ball mills you can use steel balls which are very resistant to wear rates, but in SAG mills its tricky as the accumulation of small steel balls due to low wear rate in the mill will affect so much your power draw, meaning that your power draw will be high whilst grinding efficiency is reduced as in SAG mills you need larger steel balls, this will cause a reduction in throughput.
