Simulation of the Energy–Force Parameters of Planetary Ball Mill Processing and Estimation of Their Influence on the Particle Size in an AMg2 Alloy/Graphite Composite Powder

Resumo

The motion dynamics of the milling bodies in the working chamber of a planetary ball mill is simulated. Numerical data on the influence of the processing conditions in a planetary ball mill (carrier rotation frequency) on the motion trajectory and the energy–force parameters of the contact interaction of the milling bodies between each other and the working chamber wall are obtained. The influence of the carrier rotation frequency and the processing time in a planetary ball mill on the particle size in the synthesized composite powder based on an AMg2 alloy reinforced by 10 wt % graphite is experimentally studied. The calculated and experimental data are compared to determine the collision power of the milling bodies (more than 0.005 W) that provides effective processing of the composite powder in a planetary ball mill.
