Product Description

The ball mill is the key equipment for crushing the materials after they have been crushed. This type of grinding machine is filled with a certain number of steel balls as grinding media in its barrel.

It is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal mineral processing, glass and ceramics and other production industries to dry or wet grind various ores and other grindable materials. Ball mill is suitable for grinding various ores and other materials. It is widely used in mineral processing, building materials and chemical industries. It can be divided into two grinding methods: dry grinding and wet grinding. According to different ore discharge methods, it can be divided into two types: grid type and overflow type.

Product Performance

Working Principle

The main working part of the ball mill is a rotating cylinder mounted on two large bearings and placed horizontally. The cylinder is divided into several chambers with partition plates, and each chamber is equipped with a grinding body of a certain shape and size. The grinding bodies are generally steel balls, steel forges, steel rods, pebbles, gravels and porcelain balls. In order to prevent the cylinder from being worn, a lining plate is installed on the inner wall of the cylinder.

When the ball mill rotates, the grinding body adheres to the lining surface of the inner wall of the cylinder under the action of centrifugal force and friction with the lining surface of the inner wall of the cylinder, rotates with the cylinder, and is carried along When it reaches a certain height, it falls freely under the action of gravity. When it falls, the grinding body acts like a projectile, impacting the material at the bottom and crushing the material. The cyclic movement of the grinding body rising and falling is repeated. In addition, during the rotation of the mill, the grinding body also slides and rolls, so a grinding effect occurs between the grinding body, the lining plate and the material, so that the material is ground finely. Since the feed end is constantly feeding new materials, there is a material surface difference between the feed and discharge end materials, which can force the material to flow. When the grinding body falls, it impacts the material and generates axial thrust, which also forces the material to flow. In addition, the air flow in the mill Movement also helps materials flow. Therefore, although the mill cylinder is placed horizontally, the material can slowly flow from the feed end to the discharge end to complete the grinding operation.
