The General Function of Ball Mills. A ball mill is a grinder used for grinding and blending materials for mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. Appearance. Ball mills have various designs and functions, ranging from laboratory-scale versions to large industrial models.
These balls may be had in two types: a soft ball Brinnell 450+ for large diameter ball mills, and a hard ball Brinnell 600+ for small ball mills. The addition of molybdenum, chromium and manganese provides an excellent microstructure for these grinding balls.
But if you are stuck in forged vs cast grinding balls dilemma and wonder if you are using the most optimum grinding media for your ball mills, we highly recommend reading it. To avoid redundancy, forged and roll-forged grinding balls are collectively called forged grinding balls in this article. We do not want to compare apples and oranges here.

1. **Mining**: Grinding balls are commonly used in the mining industry to crush and grind ore into smaller particles. They are placed inside grinding mills, such as ball mills or SAG (Semi-Autogenous Grinding) mills, where they help break down the ore into smaller, more manageable pieces for further processing. 2.

Ball Mills: 1"-4" grinding balls are recommended. BALL CHARGE QUALITY. You should always test grinding media balls from a new source or supplier. This usually requires testing pilot-scale batches of grinding balls in an industrial mill using the marked-ball test. Compare their wear rates with those of your current supplier.
The correct sizes are often determined by trial and error, primary grinding usually requiring a graded charge of 10-5 cm diameter balls, and secondary grinding requiring 5-2 cm. Concha et al. (1988) have developed a method to calculate ball mill charge by using a grinding circuit simulator with a model of ball wear in a tumbling mill.
