A Power Model For Fine Grinding HIGmills AR Heath1 V Keikkala2 A Paz1 and H Lehto2 1 Outotec Perth Western Australia 2 Outotec Espoo Finland Abstract 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
Ball mills are among the most variable and effective tools when it comes to size reduction of hard brittle or fibrous materials The variety of grinding modes usable volumes and available grinding tool materials make ball mills the perfect match for a vast range of applications
In the figure below the range of expected throughput for different ore types are plotted for a fixed grinding circuit each ore type can process between 80 and 120 of the design throughput An alternate power model was used to estimate mill throughput using the same mill sizes In this case a greater variation in throughput was predicted for the samples using the alternate power model – or was more sensitive to
Population Balance Models for Predicting Grinding Mill Performance Comminution represents one of the major mineral recovery from low grade ores Efficient mineral recovery in a typical lowgrade ore grindingflotation process depends on grinding the ore small enough to liberate mineralization without producing excessive slimes
