Numerical Analysis of the Ball Mill Coupled with Vertical ...

The motion equation of the grinding cylinder is deduced, which is based on the dynamic analysis of the grinding cylinder of the ball mill coupled with vertical vibration. Numerical model of vertical vibration ball mill is built and used to study the motion of grinding cavity media and grinding efficiency. The simulation results show that the distribution status of the grinding media in each ...
