2.2 Bond Work Index The term standard Bond grindability method/test is a closed-cycle dry grinding and screening process, which is taken into consideration until the steady conditions are obtained [8], [9] and [10]. Fig. 1(a). View of Lucky Cement Limestone For this purpose machinery is …
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. The Bond Work Index W i expresses the resistance of the material to grinding to a specified product size
A bond is an abrasive material used to held abrasive particles together. The bonding material does not cut during the grinding operations. Its main function is to hold the grains together with varying degrees of strength. The different standard grinding wheel bonds are …
