Hardgrove Grindability Index Wikipedia
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. As grindability depends on many unknown factors, HGI is determined empirically using a sample mill according to the following prVOLUME BASED CLOSEDCYCLE HARDGROVE ,11· Grindability characteristics of coal or minerals have been studied a wide range of grinding parameters by many researchers (Berry & Bruce, 1966;Smith & Lee,

Roll Crusher an overview ScienceDirect Topics
Some examples from AS 4264.1 include Hardgrove grindability index (AS 1038.20) which requires 1 kg at 4.75 mm top size, and total moisture (AS 1038.1 Method A and B) 300 An assessment of grindability index of coal ScienceDirect,2002420· In Hardgrove test, grindability index is determined when a constant crushing pressure (29 kg) is applied over some constant weight of coal (50 gm) to grind it in unit time, and undersized material (below 74 μm) is weighed to calculate the index. Therefore, highmoisture coals with less density and higher volume will get more
