Read Moredesign a primary ball mill from a rod mill work index rather than a ball mill index, because the industrial mill will operate over a coarser size reduction range as measured in the rod mill test, which may exhibit different grindability characteristics than would be observed at the ball mill index range. Table 2 compares the typical range of Hardgrove Grindability Index . Hardgrove Grindability Index (short HGI) is a measure for the grindability of coal. Grindability is an index, therefore it has no unit. The smaller the HGI, the harder is coal texture and less grindable is the coal. Grindability is an important factor for the design a coal mill.

Read More29, Ball mill performance is an indicator for showing the material amount passing through the mill per unit time.The drum mills productivity depends on the initial and final products size, the ore grindability, the mill size, the mill type, mill speed, the grinding balls degree filling, the circulating load value, and the classifier efficiency. With Hardgrove grindability indices and the work indices calculated from Aplans formula, capacity of the roller-race pulverizer and grindability of the Mae Moh lignite should be investigated in detail further. Keywords approximate work index, Hardgrove grindability index, Mae Moh lignite, Songklanakarin J.
Read MoreThere are 4 types of mill in service today 1. Ball Mill (BM) historically the mill of choice, it still predominates today and accounts for 85% of all cement mills installed globally 2. Vertical Roller Mill (VRM) commonly used for grinding of granulated slag but increasingly also for cement grinding and accounts for approximately 15% The grindability of the fuel directly impacts the overall efciency of the combustion process and as such it is an important parameter. In the present study, the grindability of different torreed biomass pellets was tested in three different laboratory mill types cutting mill (CM), hammer mill (HM) and impact mill
