Mill Trajectory Modelling Multotec utilises MillTraj software to predict the influence of mill liner design on the trajectory of grinding media, and to analyse the wear rates of liners according to the mineral being processed. This provides Multotec with a fundamental guideline when designing efficient mill liners. This specialised trajectory modelling measures the variable speed to demonstrate the impact of mill speed. The display features all representative liners and mill charge with a clear Perspex screen on either side in order to assess the trajectory pattern of mill charge during operation. The study of the motion of grinding media in mills led to the development of this customised modelling software. Benefits of Mill Trajectory Modelling Informs selection of lifter angles and heights related to: mill application, mill size, mill speed, filling and ball size Assesses current comminution circuit parameters Monitors the condition of comminution and other equipment Indicates design improvements Simple to use with known mill parameters
