  • Effect of ball size and powder loading on the milling

    1 Introduction Wet ball mill is one of the most predominantly used method for the purpose of mixing and grinding of raw materials in laboratories and industry , , The ball mill process is very complicated process governed by many parameters, such as ball size, ball shape, ball filling, slurry loading (with respect to ball amount), powder loading with respect to the amount of total slurryTo this end, a laboratoryscale ball mill was used to evaluate the variation of wear process of the lifter in different milling conditions of mill speed, ball filling, grinding media size and shape Besides, a wear prediction method was used to compare and validate the experimental resultsEffect of the operating parameter and grinding media ontake away most of the heat generated in the grinding process As in creep grinding, bumout of the coolant causes a steep rise in contact temperature of the workpiece 1 Introduction Cost, quality and productivity in grinding processes are all dependent on energy consumption and process efficiencyEnergy and temperature analysis in grinding
