In Mineral Processing Design and Operations (Second Edition), 2016. 10.2.4 Operation of Vertical Mills. Vertical stirred mills are usually charged with media occupying 80% of the mill volume which is in sharp contrast to tumbling mills that are seldom charged more than 40% of their volumes to allow space for the tumbling action to develop. The stirred mills are charged with a media size …

A magnetite middling was used to compare the liberation effect of the magnetite fine ground by a vertical stirred mill and a ball mill. The magnetite middling contained a high content of magnetite intergrowth with the particle size mainly distributed in the range of 40–150 μm.The new generated −38 μm products were concentrated by magnetic separation.

The specific energies (SE) shown in Table 1 are based on net power. Prony brake calibration data was used to determine the net power for the pilot vertical stirred mills (, 2011).The no-load power draw of one of the VTM-1500 installed at Minas-Rio was measured during the unloading of the ball charge.

By using a vertical stirred ball mill as a representative example, the simulation capabilities of the DEM should be established on the one hand while on the other, the grinding process should be evaluated by the motion of the grinding media that is caused by the agitator. In order to assess the accuracy of the simulation, the power consumption ...

Vertical stirred mills have been widely applied in the minerals industry, due to its greater efficiency in comparison with conventional tumbling mills. In this context, the agitator liner wear plays an important role in maintenance planning and operational costs. In this paper, we use the discrete element method (DEM) wear simulation to evaluate the screw liner wear.

Stirred media mills are relatively new to mining industry, and several new technologies have been developed such as the VXPmill (vertical stirred mill). There is little technical understanding of optimizing and scaling-up of the VXPmill. This thesis addresses both of these issues and therefore supports commercial applications of this vertical stirred mill. Stirred media mills are …

The stirred ball mill has been found to be more energy efficient than the tumbling ball mill. An energy reduction of 50% was possible for a product size of 6 microns when the stirred ball mill was employed instead of the tumbling ball mill. The energy input per ton of grinding media in the stirred ball mill could be 10 times higher than for the ...
