Ball mill is an efficient tool for grinding materials like ores, chemicals, ceramic raw materials , paints etc. in to fine powder or fine paste by grinding in a wet way. The Ball Mill operates by rotating a cylinder with grinding balls like steel, CI, ceramic and pebble balls as grinding media. Material fed through the mill is crushed by impact and grounded by attrition between the balls and also the internal cascading effect reduce the material in to a fine powder. Ball Mills usually have liners inside which are replaceable when they wear. Liners will be of wave shape which key the ball charge in to the shell and prevent the slippage.

The rotation of the powder mixer is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter is, the slower the rotation will be. Ball Mills are generally used to grind material ¼" and finer, down to the particle size of 20 - 75 microns.

To achieve reasonable efficiency, the ball mills are to be operated in a closed system, with oversize particles continuously being re-circulated back to the mill and to be reduced
