The four most common coal pulverizers types are: Ball-Tube Mills. 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. Impact Mills

With a ball mill . 1 To pulverize crushed coals in a ball mill, you start by feeding the mill with crushed coal. Then the grinding media crushes and grinds the coal in the rotating chamber. 2 Airflow carries the pulverized coal out of the ball mill. 3 Next, you'll need to use the mill classifier to separate the fine coal particles from the airflow.

A pulverizer reduces materials like Limestone and gypsum at high speeds resulting in smaller particle sizes. Centrifugal force powers the pulverizers to grind feed materials down. Pulverizing mills and machines can be used for a variety of applications. Pulverizing is typically defined as reducing to 25 mesh (0.7 mm) and beyond.
