Know the "ball mill"

Also known as ball mill. A common device that is ground or ground.

The material is crushed and mixed by the impact of the falling grinding bodies (steel balls, pebbles, etc.) and the grinding of the grinding bodies and the inner wall of the ball mill. When the ball mill rotates, due to the friction between the grinding body and the inner wall of the ball mill. Bring the grinding body in the direction of rotation and then fall. The material is continuously crushed. According to the shape of the body can be divided into cylindrical ball mill, cone mill and tube mill (also known as tube mill) three. The advantages are: (1) It can be used for dry grinding or wet grinding; (2) The operating conditions are good, and the grinding is carried out in an airtight machine without flying dust; (3) The operation is reliable, the grinding body is cheap, and it is easy to replace; (4) Can be intermittent operation, but also continuous operation; (5) crush the explosive material, the mill can be filled with inert gas instead of air. Disadvantages are: (1) large and bulky; (2) strong vibration and noise during operation and a solid foundation; (3) low work efficiency and high energy consumption; (4) friction loss between grinding body and machine body Very large and will contaminate the product. Widely used in crushed hard material.
