    Why Pulverized Coal Is Used In A Power Plant Bright Hub

    Jan 29, 2010 There is one important characteristic of coal that decides the type, size, and power required for pulverizing. This is the grindability of coal and is denoted by the Hardgrove Grindability Index or HGI. Grindability in general is a function of the grade of coal. Sub-bituminous coal from the Indian sub-continent has an index near fifty.
