Optimization Of Coal Grinding Mills

May 01, 2012 Two samples of coal Indonesian and Chinese were used to optimize the grinding conditions of the hammer mill. The results of the proximate analysis and the Hardgrove Grindability Index HGI of coal samples are provided in Table 1. Not only was the moisture content of all samples below 25, but the energy content values were all below 25.0 MJkg. The samples were lighter in color than
