Waterfall mode motionspeed mode with flying of grinding balls. Picture 1. Grinding bodies in cascade (a) mixed (b) and waterfall (c) mill operation modes. Cascade mode motion of grinding balls carried out at low drum speed. At start-up of a mill the grinding material rotated by a certain angle and grinding balls start to move by closed path.

Cement mill ResiduePage 1 of 1

Re Cement mill Residue. Hi Jatinder You could increase the speed of your separator rotor i.e. increase recirculation load. But you may then experience an excessively high blaine value. The best way to make a balance on mesh passing and blaine is to play around with feed tonnage and separator rotor speed. Branco. Reply
