Hardgrove Grindability Tester measures relative ease of pulverization of coals compared to standard coals in accordance with ASTM D409 Hardgrove Machine Method.The resulting Hardgrove Grindability Index (HGI) provides a measure of the energy required in a grinding process or a measure of yield for given energy input.

Grindability is an important factor for the design a coal mill. As grindability depends on many unknown factors, HGI is determined empirically using a sample mill according to the following procedure: Procedure of measurement 50 g of air dried coal featuring a grain size in the range between 0.6 and 1.18 mm are filled into the sample mill and a ...

The Hardgrove Grindability Tester is the ASTM recommended apparatus for determining the grindability of coal, petroleum coke and for ascertaining the ease of pulverization of a wide variety of materials. The Hardgrove grindability Tester is essentially a miniature pulverizer.

Grindability is an important factor for the characteristic of the brittle raw materials by the design the mills. As grindability depends on many unknown factors, hardgrove grindability index (HGI) is determined empirically using a sample mill, according to the following procedure.

Jul 23, 2010· Mar 17, 2013· Actually we are more worried about mill and PF pipe wear and coal quality. Our boiler is designed for Indian bituminious coal of CV-5000kcal/kg, VM-30%, ash- 25% but we are now receving coal with about 42% ash content, VM- 17 to 23%, and CV- 4250 Kcal/kg(ADB) low sulpher coal with HGI 47-50. I want some more suggestion to prevent mill wear.
