Coal Pulverizer Design and Suppliers

Coal Pulverizer Design and Operation

The three types of coal pulverizers used in the United States are:

(1)ball tube mills.

(2)bowl mills(also called roller-race mills or vertical spindle mills)

(3)hammermills.

Coal Pulverizer Design Ball tube mills are rotating horizontal cylinders containing steel or special alloy balls. Coal intermingled with the balls is crushed by the impact and grinding action of the balls as the mill rotates. Hot air flowing through the ball mill carries coal particles to classifiers situated at both ends of the mill (Fig.1). Large particles rejected in the classifiers are returned to the grinding zone for further size reduction. Small particles passing through the classifier exit the mill through piping leading to burners in direct fired systems and to cyclone collectors in indirect fired (storage bin) systems.

Coal mill process

Coal is mined by explosion, then crushed by coal crusher into small pieces. In this coal pulverizer suppliers, several types of coal crusher are used. Jaw crusher, impact crusher, cone crusher can be used as coal pulverizer.

After crushing, crushed coal enter into the coal mill for grinding. Usually a complete coal milling line includes coal mill, impulse dust cleaner, piping device, cyclone collector device, classifier. The stones are squeezed by roller and ring into powder, the powder is collected by cyclone collector. In order to ptotect the environment, we also install the cloth deduster.
