Maximizing wear resistance of balls for grinding of coal

2.4.. Wear testing procedureThe tests were performed according to the following steps: (1) Run-in: The balls were submitted to 30. h of wear in the pilot-plant ball mill, grinding coarse quartz sand (0.3–2.5 mm).. This step provided the removal of a layer of about 100 ; μm, thus removing oxide scales and other defects from the surface. (2)
