According to different work requirements and material characteristics, ball mills can be divided into various types, including dry ball mills, wet ball mills, intermittent ball mills, and continuous ball mills. Dry ball mills are suitable for grinding dry materials without the need for adding liquid media. Wet ball mills add water or other liquid media during the grinding process to improve grinding efficiency and reduce energy consumption. Intermittent ball mills only process one batch of materials at a time, and after processing one batch, proceed to the next batch. Continuous ball mill material continuously enters and exits the cylinder, achieving continuous production.

The ball mill mainly consists of a rotating cylinder, a driving device, and a feeding and discharging system. The material enters the cylinder through the feeding system and rotates together with the grinding medium (steel ball) inside the cylinder. During the rotation of the cylinder, relative motion occurs between the material and the steel ball, as well as between the material and the cylinder, thereby achieving grinding and mixing of the material. After a certain period of grinding, qualified materials are discharged through the discharge system to complete the entire processing process.

The wet ball mill is mainly composed of feeding section, discharging section, rotating section, transmission section (including reducer, small transmission gear, motor, electric control) and other main parts. During work, an appropriate amount of water is added according to the characteristics of the material. The grinding steel ball rises to a certain height with the rotation force of the drum, and then falls under the action of gravity to strike the material. Due to the movement between the grinding bodies during the rising process, it has a grinding effect on the material. In this way, under the cycle of impact and grinding, the material is ground and discharged from the machine, entering the next process.

Wet ball mill refers to the ball mill equipment that uses wet grinding technology for grinding. This equipment needs to humidify the raw materials before grinding, and then grind them. Its application range is quite extensive, commonly found in fields such as mineral processing, chemical industry, ceramics, etc.
