Simulation Method for Particle Comminution Process Considering Dependence on Particle Size and Impact Velocity in Breakage Modes

Comminution process is widely used in industry to produce fine particles. We developed a mathematical model of comminution order analyze particle size reduction an impact pulverizer. In our model, it assumed that parameter a, which represents breakage modes, depends on both velocity and the To obtain dependence, particle-size distribution was measured experimentally before after using jet-mill. implemented into simulation based computational fluid dynamics (CFD) discrete phase (DPM). It confirmed results coincide with experimental ones rotary mill. Therefore, we conclude important consider dependence as well modes.
