The coal received by the plant from the mine varies widely in size. It is necessary to make the coal of uniform size before passing the pulverizer for efficient grinding.

Ball mill Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

Coal dust Wikipedia

Coal dust is a fine powdered form of coal, which is created by the crushing, grinding, or pulverizing of coal. Because of the brittle nature of coal, coal dust can be created during mining, transportation, or by mechanically handling coal.It is a form of fugitive dust.. Grinding coal to dust before combusting it improves the speed and efficiency of burning and makes the coal easier to handle.
