· The Hardgrove Grindability Index (HGI) test is based on Rittinger''s theory that "the work done in grinding is proportional to the new surface produced", . The index varies from 20 to 110, with a lower HGI indicating a coal is harder to grind and more energy will be required to reach the required degree of fineness.

The Hardgrove index is based on fine products for a given number of revolutions, and the Bond work index is based on the mass of a fine product multiplied by the number of revolutions of the mill. However, it should be taken into account that other factors may also influence the given input torque in the grinding mill, such as friction, cohesion, adhesion, and material volume flow characteristics.
Limestone feed systems will have to handle limestone feed rates of about 10- 30% of the coal feed rate. Several potential limestone preparation and injection schemes are possible which would allow injection through the burners, secondary or tertiary air ports
