Apr 01, 2017 1. Introduction. Fine grinding in stirred bead mills is becoming increasingly common in the mineral processing industry. Typically they are used as regrind mills in concentrator circuits where the reduced volume of high-grade ore justifies the high energy input, however they are now also being considered for some duties previously performed by ball mills (Capstick and Currie, 2012).
A grinding power model has been developed to predict the power draw of Outotec’s vertical fine grinding mill (HIGmill). The model is based on a combination of laboratory, pilot and full-scale measurements taken over a range of process conditions.
Outotec HIGmill for ultra fine grinding The HIGmill comprises a mill body, shaft with grinding discs, shell mounted counter rings, gearbox and drive. The grinding chamber is filled up to 70 % with grinding beads. Rotating discs stir the charge and grinding takes place between beads by attrition. The number of
