Characteristics of Mae Moh lignite: Hardgrove

202192To determine the relative grindability of coal, i.e. whether it is easy or difficult to pulverize, the Hardgrove test is a standard method widely used Klima, 1999. The Hardgrove grindability index HGI can be then estimated from the test. The higher the index is the easier the coal to be pulverized.

Grindability an 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.
