Application of PFC3D to simulate a planetary ball mill ...

The simulation was facilitated through a series of hemp grinding tests using the planetary ball mill to examine the power draw of the mill. The test results identified that grinding speed had a significant effect on the power draw of the mill. The power draw data were used to calibrate the discrete element parameters for different grinding speeds.
