Why Pulverized Coal is Used in a Power Plant

Pulverizers come in different models and are a very important auxiliary of a power plant. Grindability 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).
