Coal Pulverizer
Pulverizers (coal pulverizer) are used to pulverize pieces of coal into fine particles (100μm) before placing into a boiler, to ensure efficient combustion. Pulverizers have three functions, pulverization, drying and classifiion. The classifiion function plays the important role of ensuring that only fine particles of the pulverized coal ......
