Analysis for Behavior of Particles in Wet Ball Milling by Means of Simulation

Abstract

Wet ball milling is a kind of methods grinding particles by collisions of balls in a slurry. It has been used for producing the raw materials, intermediate-products and end-products because it has features as high versatility, high grinding performance and easy to increase the size of equipment. However, the grinding by the wet ball milling has been operated without enough understanding grinding mechanisms because it is difficult to observe and analyze grinding processes. Thus, analyses by using a simulation have been introduced in order to understand the grinding mechanisms. In this paper, we introduced two examples. One example is that the behavior of particles around the balls in liquid was analyzed by the simulation method coupling DEM with CFD. The other example is that the simulation method for representing the dynamic and breakage behavior of particles around the balls in liquid was developed.
