Vertical Grinding Mill (Coal Pulverizer) Explained - saVRee

Coal pulverizers are used to dry, grind and classify. Drying is achieved as hot gas passes through the pulverizer and removes moisture from the pulverized coal. The hot gases used should have a low oxygen content, this reduces the likelihood of accidental combustion within the mill. It is possible for hot gases to be taken directly from the ...

Coal Fired Thermal Power Station Explained - saVRee

Coal pulverizers increase the coal's contact surface area with the air by grinding the coal into small pieces. The pulverizer also dries the coal in order that combustion can more easily occur (reduced moisture content). The heat to dry the coal is recovered from the boiler exhaust gas stream. Pulverized coal from the pulverizer is blown into ...
