Hardgrove Grindability Low
Hardgrove grindability index and approximate Hardgrove test is a standard method used widely in the coal industry. To determine the relative grindability of coal, whether it is easy or difficult to pulverize, the Hardgrove grindability index HGI can be estimated from the test. A higher index indies the coal is easier to pulverize.

Clinkerization
Procedure. Suppose on analysis, the samples placed at 1400 0 C, 1450 0 C and 1500 0 C shows free lime of x %, y % and z % respectively. The burnability index will be calculated as: FLS B. I={(x/) +(y/) +(z/)} x 100/3. An index below 80 is considered as easy burn, 80120 is normal and above 120 is considered as hard burn material.
