Results of studies aiming at description of the grinding rate are discussed in the paper. During the milling process the ball numbers and batch weight were changed. The main purpose of the investigations was to determine the specific rate of grinding for different particle sizes. The grinding rate was expressed in a form of a correlation equation. Results of analysis were used to determine the process kinetics and the rate of grinding for particle fractions. The change of mean particle size in time was studied and the influence of ball composition and batch weight on the rate of grinding process and specific grinding rate was described.
