What Is A Ball Mill?

Ball mill is the key equipment for grinding the material after being broken. Ball mills are widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal dressings, and glass ceramics. The ball mill is suitable for grinding various ores and other materials and is widely used in mineral processing, building materials and chemical industries.

Classification Of Ball Mill

The ball mills can be divided into dry ball mill and wet ball mill according to the process conditions.According to different materials will choose different grinding sub. The grinding sub can be roughly divided into metal and non - metal categories. The grinding sub of ball mill is steel ball, the grinding sub of rod mill (MBS type rod mill) is a steel bar, and the grinding sub of ceramic ball mill is ceramics.

Wet ball mill: Grind the material into a certain concentration of pulp, the general concentration is 60 ~ 70%.

Dry ball mill: Grind the material into the desired mineral powder. The thickness of the ore powder should be based on the grading of the grinding body.

Ball Mill Features:

Energy Saving and Less Power Consumption: The matching of the drive and the grinding media can greatly lower the power consumption.
The Flexible Design of the Discharging Port: The customers can decide whether the iron removing the device is required or not according to their demands.
The Bigger Feeding Size: The reasonable design of the feeding port can increase the feeding output.
Taking the Closed System to Decrease the Dust: Closed system, negative pressure conveying, small dust.

Working Principle

The material is fed into the mill by a drum feeder through a spiral cylinder with a hollow shaft. The grinding medium is installed in the barrel body. When the barrel body rotates, the grinding medium is attached to the wall liner surface of the barrel body due to the inertial centrifugal force. After being rotated together with the barrel body and brought to a certain height, the materials in the barrel body are broken by gravity.

BALL MILL WORKING PRINCIPLE

In addition to the cyclic movement of ascending and falling, the grinding medium also causes sliding and rolling in the rotating cylinder body, causing grinding action between the grinding medium, the lining plate and the material to grind the material.
