In the production industries of cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation and glass ceramics, ball mills are the key equipment for crushing materials after they are crushed. It can dry or wet pulverize various ores and other grindable materials. The ball mill is suitable for grinding various ores and other materials, and is widely used in mineral processing, building materials and chemical industries.
The ball mill is composed of a horizontal cylinder, a hollow shaft for feeding and discharging materials, and a grinding head. The cylinder is a long cylinder. The cylinder is equipped with an abrasive body. The cylinder is made of steel plate. A steel lining plate is fixed to the cylinder. The abrasive body generally, it is a steel ball, and it is loaded into the cylinder according to different diameters and a certain proportion. The grinding body can also be used in the steel section. The material is selected according to the particle size of the grinding material. The material is loaded into the barrel by the hollow shaft at the feed end of the ball mill. When the barrel of the ball mill rotates, the grinding body is attached to the barrel lining plate due to the inertia and centrifugal force and friction. Taken away by the cylinder, when brought to a certain height, it is thrown down due to its own gravity. The falling abrasive body crushes the material in the cylinder like a projectile.
There are many types of ball mills, which can be divided into dry and wet grinding methods. According to the different ways of mine discharge, it can be divided into two types: lattice type and overflow type. According to the shape of the barrel, it can be divided into four types: short barrel ball mill, long barrel ball mill, tube mill and cone mill.
