Pulveriser in Thermal Power Plant | Bowl Mill | Ball Mill

Hot air flow is induced through the mill in order to dry the coal and remove the fines from the pulverizing zone. If the rate of feed is increased, coarser product will be obtained and if the speed of rotation is increased the fineness for given capacity increases. During grinding, balls themselves wear and are continuously replaced by new ones.

Ball Milling - an overview | ScienceDirect Topics

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134-141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
