Vertimill® - Metso Outotec

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.

Stirred Mill - an overview | ScienceDirect Topics

The Vertimill® is a vertical stirred mill that uses a helical screw to impart motion in the charge. Mechanically, the Vertimill is a very simple machine with an agitating screw suspended into the grinding chamber, supported by spherical roller bearings, and driven by a fixed speed motor through a planetary gearbox.

Grinding Media Piece Weight Calculation

the wear of grinding media with hardness 350 – 400 Brinell is for big balls of 80 – 200 g/t (10 – 25 g/kWh) and for small balls and cylpebs of 35 – 120 g/t (3 – 10 g/kWh). The wear is much reduced for grinding media chromium alloyed steel, with hardness 600 – 700 Brinell [3]. The total wear of grinding media, during the
