The effective mill power emp can then be defined relative to the total mill power tmp.Emp is the per-centage of total mill power draw delivered to the coarse ore and is defined as emp tmp x cseff 1 the ball mill circuit functional performance equation.A practical measure of a given circuits productivity as.
View AllDiscrete-element method dem modelling is a powerful tool for studying particulate systems within the mineral processing industry.Dem simulations were conducted to investigate the power draw, load behaviour, and impact energy profile of an experimental ball mill under different milling conditions.
View AllDiscrete element method simulations of a 15-scale laboratory ball mill are presented in this paper to study the influence of the contact parameters on the charge motion and the power draw.The position density limit is introduced as an efficient mathematical tool to describe and to compare the macroscopic charge motion in different scenarios, i.A.
View AllThe mill shell.The measured power is 3,190 kw at mill shell, so the model predicts high by 298 kw, or 9.However, by substituting the recommended 5 allowance for a cone end instead of austins cone allowance results in a 148 kw of power generated in the cone, for a total of 3,113 kw power draw at the mill shell.The measured power is 3,190.
View AllA more quantitative comparison can been made by comparing the power draw of the mill, resulting from collisional interaction of the ball charge with the liner and end walls.The plot below shows the temporal dependence of the total force amplitude and the power draw.
