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. The power draw of the mill is influenced by a variety of factors, ranging from simple geometric factors like …

The Dry Grinding Process. The Attritor dry grinding process is achieved in a stationary tank by means of a rotating shaft and arms that agitate the media into a random state of motion of internal porosity called kinematic porosity. In this expanded condition, the media and particles are free to move, collide and impinge upon each other.
