  • Correlation Between Power and Lifters Forces in Grinding Mills

    Apr 11, 2019· Correlation Between Power and Lifters Forces in Grinding Mills Abstract: Using a discrete element method (DEM) software, this paper develops a methodology to obtain the forces acting on each face of the lifters and on the liner plates of a grinding mill and its correlation to the mill torque and power. This analysis gives a clear view of the contribution of each lifter face to the torque andVXPmill for fine & ultra fine grinding Fruitful,There is a large gap between the tip speed and power intensity of the low-speed vertical mills and the high-speed horizontal mills. The VXP mill bridges the gap between high-speed and low-speed mills. The VXPmills are designed for fine and ultra fine grinding applications. In practice, the mill performs best when the feed has a normal distribution.
