8.1 Grinding 8.1.1 Grinding action Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type. These mills exist in a variety of types - rod, ball, pebble autogenous and semi-autogenous. The grinding action is induced by relative motion between the particles of media - the rods, balls or pebbles ...
Ball diameter: mm; Hardness: normal, higher, high; The most common are grinding balls of carbon and low alloy steels, used primarily for grinding raw materials. Such grinding media for ball mills are produced by hot-rolling, forging and stamping. Balls are hardened by microalloying steel and heat treatment.

The wear of grinding steel balls is related to the surface area of steel balls. In general, the steel ball in the grinder has both impact and abrasion effects, so the wear is proportional to the n power of the diameter of the steel ball, and the value of n is between 2 and 3. Table 1-11 The Relation between Steel Ball Diameter and Material Size

optimum ball diameter" (Taggart, 1945). • Test mills used for media sizing investigations need to be reasonably large (at least 0.4 m in diameter was suggested), depending on size of balls and ore being tested. • Ball surface wear rate is approximately constant, but with variations due to hardness, and other factors. Consumption
Steel balls produced for the bearing industry are often made in standard bearing steel 100Cr6 – AISI 52100 (HRC = 60-66) and are produced through a standardized process, of which grinding is a key operation. The diameter of balls range from very small (0.05mm) to large (300 mm), with a majority of 20-30mm. RAW MATERIAL
