  • MODELING OF THE PROCESS OF COAL GRINDING

    The coal was crushed in the Coke Department of Cze-stochowa Plant. The numerical determination of grain size distribution of crushed coal was made and the re-sults obtained in this way were compared with the re-sults of laboratory analyzes of grain made. In this pur-pose the results of the grinding process in a hammer crusher (Figure 1).
