    Mathematical Models Of Particle Size

    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 multi-stage comminution process, the particle size distributions of products are log-normal. The product particle size distribution depends on the crushing process intensity stage.
