Hardgrove Grindability Index Limestone Process. Bond grindability index of li neOct 15 The Bond Work Index BWI or Wi is defined as the calculated specific energy kW ht applied in reducing material of infinite particle size to 80 passing 100 m 25 The higher the value for Wi the more energy is required to grind a material in a ball mill 10 26.
The Hardgrove grindability index value is influenced by petrographic composition of coal. The analysis of grindability of British coal confirmed wide relation of HGI values between the quality group of coal, volatile combustible matter contents, carbon and hydrogen (Fitton, 1957). The increase of contents of volatile combustible matter improves the grindability up to the contents of volatile ...
