Comminution kinetics of steel slag: influence of microwave pretreatment
Appliance of microwave treatment as a preceding step in the comminution processes has been recognized in many scientific and industrial communities. This work presents the effect of such technique on the comminution efficiency of steel slag, in term of process kinetics. Steel slag samples, defined as diverse monosized fractions, have been used in this study. Microwave treatment was conducted in a domestic, multi-mode microwave unit at a constant power input. Dry grinding experiments were performed in a laboratory, planetary ball mill. Dynamic aspect of the process was observed at a constant process conditions: operational speed, pot volume, number of balls, etc. Process kinetics was expressed via selection function parameter. Microwave treatment significantly influences steel slag comminution kinetics. Divergence in determined selection function parameters depends on the initial sample size. This investigation indicates possible implementation of microwave treatment in steel slag processing for further application.
