Structure and Application of Grinding Ball Mill
Ball mills, vertical mills, jet mills and other mills, as important
grinding equipment, can be seen everywhere in industrial sectors
such as mineral processing, building materials, cement, coal,
chemical, electric power, light industry and metallurgy. Among
them, the ball mill is the most widely used. The main component of
this type of pulverizer is a slowly rotating cylinder with grinding
media. Because the ball mill has a simple and firm structure,
reliable operation, simple maintenance and management, and can run
continuously for a long time, strong adaptability to materials,
large crushing ratio (up to 300 or more) and large production
capacity, so it can meet the needs of modern large-scale industrial
production.
Ball mill is the key equipment for crushing materials after crushing. This type of ore grinding machine is equipped with a certain number of steel balls as grinding media in its cylinder.
Grinding Ball Mill is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal beneficiation, and glass ceramics and other production industries to dry or wet grinding various ores and other grindable materials. The 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 dry and wet grinding methods. According to different ways of discharging, it can be divided into grid type and overflow type.
Ball mills are divided into many types due to different specifications, unloading and transmission methods, but their main structures are roughly the same. The ball mill is mainly composed of a cylindrical barrel, a liner, a compartment plate (only available for multi-chamber mills), main bearings, feeding and discharging devices, and transmission devices.

Grinding Ball Mill Working Principle is as Follows:
Cylindrical cylinder body 1, end cover 2, bearing 3, transmission
gear ring 4 and other components. The cylinder 1 is filled with
steel balls or steel rods with a diameter of 25-150mm, which are
called grinding media. The filling amount is 25%-50% of the
effective volume of the entire cylinder. There are end covers 2 at
both ends of the cylinder. The end covers are connected with the
flanges of the end of the cylinder by bolts. There is a hole in the
middle of the end cover, which is called a hollow shaft. The hollow
shaft is supported on the bearing 3 and the cylinder can rotate. A
large gear ring 4 is also fixed on the cylinder. In the drive
system, the motor drives the large gear ring and the cylinder
through the coupling, reducer and pinion to rotate slowly. When the
barrel rotates, the grinding medium rises to a certain height with
the barrel wall, and then falls or drops down in a parabola. Due to
the hollow shaft on the end cover, the material is fed into the
cylinder from the hollow shaft on the left, and gradually spreads
to the right. When the material moves from left to right, the
rotating cylinder will bring the steel ball to a certain height.
Falling crushed the material, and a part of the steel ball in the
barrel has a falling state to grind the material, and the entire
movement process is also the crushing process of the material.
