Grindability of torrefied wood chips and wood pellets
The Hardgrove Grindability Index (HGI) test used to define the grindability of the specific mass of brittle materials like coal was developed based on Rittinger s theory . However it has been shown that milling is a volumetric process hence the constant mass which implies the smaller volume for denser fuels fails to represent the direct

Hardgrove Grindability Index (HGI) Standard Reference
The Hardgrove Grindability Index is calculated on four splits (or portions) two each taken from the two reserved cans. The results are averaged to give the index for the entire lot. Cans of standard reference sample are shipped to customers upon request along with a questionnaire designed by ASTM to obtain data on the quality of the sample.

Re Hardgrove Grindability Index 09/23/2010 6 02 AM Indeed ball and race type mills are not designed for products with a HGI much lower than 50 (some suppliers decline responsibility if such coal is grinded in their mills) since mechanical pressure is applied with the balls if the product is too hard to grind there won t be enough product

Grindabilityan overview ScienceDirect Topics
Grindability refers to the ease of pulverizing a coal sample compared to certain reference coals. The standard method of coal grindability is called Hardgrove (ASTM D409) though this method does not provide reproducible and repeatable results for hard coal. Another method that can be accepted for petroleum coke is the test method ASTM D5003.
