| Hardgrove test | Mining | This test utilizes a special grindability mill of the ring-and-ball type, in which a 50-gm portion of closely sized coal is ground for 60 revolutions. This method is of the constant-work type; i.e., a fixed amount of work is expended on each coal, and a grindability value is determined from the size composition of the ground material.
