INTRODUCTION The resistance of ore samples to breakage (or hardness) is measured through grindability testing. Several grindability tests have been developed over the years for different applications and each test has its own strengths and weaknesses. Grindability testing is a compromise between test cost and its deliverable(s).
The grinding of coals for coal preparation has been studied extensively by previous investigators, but no similar work has been done on coal lithotypes (l-4). However, the different natural breakage characteristics of coal lithotypes have been recognized and utilized by the coal industry (5,6) to develop the Longway Burstlein process (7) for the …

A new method is proposed for measuring the grindability of solids and the energy efficiency of grinding mills. The method is based on a similarity law of fracture mechanics for elastic materials in conjunction with the self-preserving character of the size distributions formed when feed particles are comminuted individually in compression. …
The grindability of gas quenching steel slag is better than heat-stew steel slag; And cement mixed with 20% of gas quenching steel slag can be used to produce portland cement (Grade 52.5), if the addition of gas quenching steel slag is 40%, which can produce P·S·A32.5 cement.

The relative grindability is the ratio of the ore to be tested to the standard ore with known grindability under the same test method and test conditions, with limestone usually used as the standard medium hard ore. Absolute grindability is the grindability value of the ore measured under the specified test method and test conditions.
