Abstract

The stirring medium mill was employed to prepare lotus leaf powder. The Variation of particle size of lotus leaf powder within 30 min at different stirring speeds were investigated. The grinding kinetics of the lotus leaf powder was studied using the analytical model of the crushing process. The grinding chamber shear rate distribution and the average collision energy of the grinding media were analyzed at different stirring speeds coupling CFD-DEM method. The results showed that the grinding rate of the lotus leaf powder increased with the increase of the stirring speeds in the range of 500～3 000 r/min. The fluid shear rate and the average collision energy of the grinding media increased with the increase of the stirring speeds.
