Ball mills are mainly used for fine grinding after crushing and are commonly used in mineral processing and building materials production lines. Ball mills can grind various metal and non-metal ores and are widely used in industries such as cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal beneficiation, and glass ceramics. They perform dry or wet grinding on various ores and other grindable materials.
product details
Bimetallic composite wear-resistant lining
The products not only cooperate with many well-known domestic enterprises, but also are exported to Southeast Asia, Africa, the Middle East and other countries and regions.
Two kinds of metal hydrothermal composite casting, the striking surface is made of eutectic high-circuit cast iron, with two different mechanical properties, good wear resistance, high toughness, is more than 2.5 times the wear resistance of ordinary Mn13Cr2 material lining.
Operational advantages
(1) Strong adaptability to materials, continuous production, and large production capacity.
(2) The crushing ratio is large, up to more than 300, and it is easy to adjust the fineness of the grinding product.
(3) It can adapt to the operation of various situations, both dry and wet operation, and can also be dried and ground together at the same time.
(4) The structure is simple, sturdy, reliable operation, simple maintenance and management, and can operate continuously for a long time.
(5) It has good sealing and can be operated under negative pressure to prevent the flying of dust.
How it works
The material enters the first bin of the mill uniformly by the feeding device through the feeding hollow shaft spiral, which has a stepped lining plate or corrugated lining plate, which is equipped with steel balls of different specifications, and the cylinder rotates to produce centrifugal force to bring the steel balls to a certain height and fall, which has a heavy impact and grinding effect on the materials; After the material reaches coarse grinding in the first bin, it enters the second bin through a single-layer bin plate, which is inlaid with a flat lining plate and has a steel ball in it, and the material is further grinded; The powder is discharged through the discharge grate to complete the grinding operation.
Case scene
Processed material: hematite
Concentrate Grade: 65.95%
The hematite can be crushed and screened, which can be crushed by a jaw crusher, and the particle size of the material does not meet the production requirements can be screened out and then crushed; In the second step, the screened material is evenly sent to the ball mill for grinding, and the spiral classifier is used for classification, and the unsatisfactory is re-ground; The third step is to send the material to the magnetic separator for magnetic separation, and finally dry to obtain iron fine powder.
