Sizing the ATOX mill The specific energy consumption depends on the grindability of the raw coal and the coal meal fineness required. The grindability is usually specified according to the Hardgrove Grindability Index HGI. The specific energy con-sumption of an ATOX coal mill based on the Hardgrove index is shown in the grindability diagram.

Jul 20, 2020 Jun 12, 2013 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.
