Study of energy-intensive mill lining during the grinding of silicon powder

Abstract

Dynamics of silicon lining an energy-intensive planetary mill was studied using experimental methods and a developed mathematical model. The transformation of the silicon powder microstructure during its mechanical treatment was investigated. It was found that this changes the granulometric composition of the mixture, resulting in a constant reformation of silicon particles formed from the agglomerates, which are crushed and agglomerated into new particles. It is shown that with increasing mechanical treatment time there is an increase in the amount of material in the lining layer. The lining speed constant was determined from the solution of the inverse problem. The theoretical calculations were in good agreement with the experimental data.
