The efficiency of vertical stirring mills has been widely recognized in the mineral processing industry. However, the scaling up and selection design of industrial equipment lacks theoretical support. By obtaining real-time power from laboratory tests on a 10L vertical mill and using DEM simulation to simulate the real-time torque of a vertical mill under the same conditions, the power is calculated and compared with experimental results to verify the feasibility of DEM method in predicting input power of vertical mills. The results show that the average difference between the predicted power of vertical mill based on DEM method and laboratory test is 5.55%, which proves that DEM method has strong reference value for predicting real time input power of vertical mills.
