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.
