The glazing in the grinding wheels takes place when the wheel is too hard or it revolves at a very high speed. Thus the glazing may be decreased by using a softer wheel or decreasing the wheel speed. The process of changing the shape of grinding wheel as it becomes worn due to breaking away of the abrasive and bond is called truing.
Bond Index Test Test conducted on a Bond Index testing mill (Bico-Braun, USA) 700ml of sample milled for 100 revolutions. New number of revolutions is calculated to produce fines equal to 1/3.5 of the total charge of the mill.
