The Ball Mill is suitable for grinding and other materials, which is key equipment that break and smash again. It is widely used in cement,
silicate products, new building materials, refractory materials, fertilizer, black and non-ferrous metal mineral processing and glass ceramics
and other production industries. It can also be used for dry or wet grinding of various ores and other grindable materials.
The ball mill is composed of feeding part, discharging part, rotating part, transmission part (reducer, small transmission gear, motor,
electric control). The hollow shaft is made of cast steel, with replaceable lining. The large rotary gear is cast with teeth processed, and
the cylinder body is lined with wear-resistant plates, ensuring excellent wear resistance. This machine operates smoothly and reliably.
According to the impact classification is divided into light, heavy；According to the length of the classification is divided into short
mill, long mill, long mill; According to the grinding medium is divided into ball mill, rod mill, rod ball mill, gravel ink; According to
the transmission mode, it is divided into center drive mill and edge drive mill. Other classification methods are according to the
process operation, continuous grinding time, etc.
The material is uniformly fed into the first chamber of the mill through the feeding device and the hollow shaft. This chamber is
equipped with stepped or corrugated lining plates and contains steel balls of different specifications. As the cylinder rotates,
centrifugal force brings the steel balls to a certain height and then they fall, impacting and grinding the material. After coarse
grinding in the first chamber, the material passes through a single-layer partition board into the second chamber, which is lined
with flat lining plates and also contains steel balls for further grinding of the processed material. Fine powder is discharged through
the discharge grate plate, completing the milling operation.
1.The production and maintenance of mechanical equipment are large, the efficiency is low and the grinding cycle is long.
2.It is a heavy-duty equipment, and the starting load is very heavy.
3.Power frequency control, easy to cause excessive grinding of materials and motor fluctuations, affecting product quality.
4.The starting torque is large and the load fluctuates greatly during operation.
5.Using star triangle or autobuck starting, the starting current is particularly large, which has a great impact on the equipment and the power grid.
Improve product quality, energy saving and consumption reduction, improve the quality of the power grid, extend the service life
of the shaft and gearbox, and extend the service life of the motor.
