Production of grinding balls resistant to abrasive wear ...

2017-9-23  Appropriate heat treatment is developed for grinding balls of diameter 20–60 mm. The microstructure of the steel formed in heat treatment is analyzed. The temperature at which martensitic transformation begins is determined. Experimental batches of 60-mm grinding balls with bulk hardness HRC 59.5 produced by the proposed technology are tested. Their performance is excellent.

Grinding balls, buy metal balls from Metinvest

A ball mill is a drum-grinding unit where balls from solid materials (steel, iron, hard alloys, ceramics, etc) are used. Most common are ball mills, where when the drum rotates and the balls rub against the inner walls, the balls are lifted until the lifting angle becomes bigger than the angle of repose. Then the grinding media are again below.
