Coal Pulverizer Purpose. Irrespective of the machine used to pulverize the coal, all coal pulverizers have a similar purpose. 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 ...
