In mining operations, jaw and gyratory crushers are generally used for primary crushing, and cone crushers are used for secondary crushing. During the past decade, however, high-pressure grinding rolls (HPGR) are being considered due to potential processing benefits such as energy savings, improved exposure/liberation and particle weakening.

Crushers are one of the major size reduction equipment that is used in metallurgical, mechanical, and other similar industries. They exist in various sizes and capacities which range from 0.1 ton/hr. to 50 ton/hr. They can be classified based on the degree to which they can fragment the starting material and the way they apply forces.

There are several methods to estimate the grindability of coals. One of the most commonly used methods is the Hardgrove Grindability Index (HGI). HGI for coal is determined by grinding 50 g of sample in a ball and ring type mill for 60 revolutions, after which the product is sieved through a 200 mesh sieve (75 micron screen) ( Speight, 1994 ).
