Effects of ball milling and high-pressure torsion for ...

2012-7-6  Pure Al powders were mixed with a 30 % volume fraction of Al2O3 powders having particle sizes of ~30 nm. The mixed powders were first subjected to ball milling (BM) and thereafter consolidated by high-pressure torsion (HPT) at room temperature under a pressure of 3 GPa for 10 turns. The Al–Al2O3 composite produced by BM and HPT (BM + HPT) had a more uniform dispersion of the

Grinding balls, buy metal balls from Metinvest manufacturer

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.
