The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AGSAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.

In this research, the effect of ball size distribution on the mill power draw, charge motion regime and breakage mechanism in a laboratory ball mill was studied using the discrete element method DEM simulation. The mill shell and crushing balls were made of Plexiglas and compressed glass, respectively. Modeling was performed using Particle Flow Code 3D PFC3D.
However, the trend is clear in that as ball mill feedrate increases the power draw falls. As can be seen the average power draw is about 12.5 MW and occurs at a feedrate new feed plus recy cle of about 6000 thr. Over a wide range of feedrates about the mean value of 6000 tph the power draw varies by only -
188.8.131.52 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter Figure 8.11. The feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 2040 water by weight.
Morrell C-model. Applies to both SAG and ball mills, with variants for grate-discharge and overflow mills. This model was developed as part of the PhD thesis of Stephen Morrell at the University of Queensland and is the model used in the JK SimMet software for determining mill power draw.
Jul 04, 2018 Yttria-reinforced copper matrix composites were prepared by dry ball milling DBM and wet ball milling WBM, respectively, followed by spark plasma sintering SPS.

This relates to a 61 of maximum power draw at a ball charge volume ...
Mill speed influences the power draw in two ways on the one hand, mill power is the lineal product of the mill rotational speed and the torque applied, so there is a lineal dependence on the other hand, the centreof gravity of the charge is shifted withspeed, creating a non-lineal dependence. The overall power draw versus mill
