The four most common types of coal pulverizers are: This type of mill consists of a rotating tube filled with cast alloy balls. Coal is introduced through two hollow trunnions on each side of the tube. As the tube rotates, the balls tumble onto the coal,crushing and pulverizing it.
coal mill in cement manufacturing Process In the cement manufacturing process, most material must be broken, such as limestone, iron ore, clay and coal etc. Limestone is the main raw material for cement production, each producing a ton of clinker needs about tons of limestone, more than 80% of raw material is limestone.
Jul 07, 2017· Oversized coal particles are returned for grinding. The coal particles of required dimension are discharged from the top of the classifier. In this ball and race mill, coal is pulverized by a combination of' crushing, impact, and attrition between the grinding surfaces.
