4 Density Of Cement Mill Ball Charge Grinding Media

Vertimill®

Motor power and media addition. The power drawn by the Vertimill motor is required to establish the grinding rate. Motor power should be measured using corrected power. As the grinding media wears fine enough to be carried out by the uprising velocity in the mill, the total media charge will diminish, and the power draw will decrease.

This test also shows that by feeding the mill with a too dilute pulp, the grinding zones between the media are not saturated, leading to high media wear rate. A variation in total ball angle can be detected and linked to grinding efficiency and charge expansion. This could help the operator to make the right decision and keep the mill
