The pulverising mill grinds the coal at a steady rate irrespective of boiler feed. 2. There is always some coal in reserve. Thus any occasional breakdown in the coal supply will not effect the coal feed to the burner. 3. For a given boiler capacity pulverising mill of small capacity will be required as compared to unit system.

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.

4. Hammer mills : The principle of operation of hammer mill is shown in Figure C. These mills have swinging hammers or bars, into the path of which is fed the coal to be pulverized. Grinding is done by a combination of impact on the large particles and attrition on the smaller ones. Hot air is given to dry the coal.

A high-speed impactor (such as a hammer or a ball) instantaneously impacts a solid object, or objects collide with each other at high speed to cause crushing. This process is used for pulverization into medium- and small-sized objects (10 cm or less). ＜Shear pulverization＞ An object is cut into small pieces by a wedge, such as a cutter.
