The Mill Filling Rate Is The Foundation Of Efficient Grinding
Wet ball mill, the filling factor of roughly grinding to 40 of the total volume of the filler as a boundary, a high filling rate is greater than 40 . the bulk density of the grinding ball mill grinding efficiency clout, larger than the surface area of the grinding media, the contact area of the grinding media and the material, the higher.
Optimum grinding test conditions were found to be 840 rpm for stirrer speed, 0.70 for ball filling ratio, 0.100 for powder filling ratio, 50 for solid ratio and 20 min for grinding time. It was also observed that stirrer speed, ball filling ratio and grinding time were directly proportional whereas powder filling ratio.
