  • MATHEMATICAL MODELS OF PARTICLE SIZE

    2012104ensp;0183;ensp;A theoretical approach to determination of particle size distribution of crushing products was presented by Kolmogorow (1941) and Epstein (1947), who proved that for a multistage comminution process, the particle size distributions of products are lognormal. The product particle size distribution depends on the crushing process intensity (stage).
