Ball mill introduction
Ball mill is the key equipment for crushing materials. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation and glass ceramics production industries, dry or wet grinding of various ores and other abrasive materials. Ball mill is suitable for grinding all kinds of ore and other materials. It is widely used in ore dressing, building materials and chemical industries. It can be divided into two types: dry and wet grinding methods. According to different drainage methods, it can be divided into two types: lattice type and overflow type.
Working principle: The most important equipment in the preparation of aerated concrete raw materials is the ball mill, which is used for the grinding of lime, gypsum, sand, slag and other materials. Only after the materials are ground and the required fineness can they be fully mixed and interacted to achieve the strength of the product. Grinding is an important process in the production of aerated concrete. The grinding process consumes a lot of power. The equipment with the largest motor capacity in the factory.
The ball mill is composed of a horizontal cylinder, a hollow shaft for feeding and discharging, and a grinding head. The cylinder is a long cylinder. The cylinder contains a grinding body. The cylinder is made of steel. A steel liner is fixed to the cylinder. The grinding body Generally, it is made of steel balls, and it is packed into the cylinder according to different diameters and certain proportions. The grinding body can also be made of steel.
Mechanical structure: The ball mill is composed of the main parts such as the feeding part, the discharging part, the turning part, and the transmission part (reducer, small transmission gear, motor, and electronic control). The hollow shaft is made of cast steel, and the inner lining can be replaced. The rotary gear is processed by casting hobbing. The cylinder is equipped with a wear-resistant liner, which has good wear resistance. The machine runs smoothly and works reliably.
The main body of the ball mill includes a cylinder body, which is lined with a lining made of abrasion-resistant materials, a bearing that carries the cylinder body and maintains its rotation, and a driving part, such as an electric motor, and transmission gears, pulleys, V-belts, etc.
Regarding the parts called blades, they are generally not the main components. The internal spiral in the component inlet of the feed end can be called its internal spiral blade, and the internal spiral in the component outlet of the discharge end can also be called its internal spiral blade.
In addition, if the screw conveyor is used in the auxiliary equipment at the discharge end, there will be parts called spiral blades in the equipment, but strictly speaking, it is no longer a part of the ball mill.
According to the material and the ore discharge method, dry ball mill and wet lattice ball mill can be selected. Energy-saving ball mill adopts self-aligning double-row radial spherical roller bearings, which has small running resistance and significant energy saving effect. In the cylinder part, a section of conical cylinder is added at the discharge end of the original cylinder, which not only increases the effective volume of the mill, but also makes the medium distribution in the cylinder more reasonable. This product is widely used in non-ferrous metal, ferrous metal, non-metal beneficiation sites and chemical and building materials industries for material grinding.
