### Grindability an overview ScienceDirect Topics

Grindability index is a measure of the ease of grinding of a given feed. Utility industries use the Hardgrove grindability index (HGI) to express this parameter. In the direct cofired system, the existing mills designed for coal are used for grinding the cofired biomass. So for a given mill, given rotation, and energy input, it is necessary to know how much biomass would be ground.
