Ball Mill Alloy Liner
The ball mill liner is used to protect the barrel and protect the barrel from direct impact and friction of the grinding body and the material. At the same time, different forms of liner can also be used to adjust the movement state of the grinding body to enhance the grinding effect of the grinding body on the material. , Help to improve the grinding efficiency of the mill, increase production and reduce metal consumption.
The high-manganese steel of the ball mill’s lining plate is gradually replaced by the alloy steel lining plate, but with the continuous application of the alloy steel lining plate in the ball mill lining plate, it has gradually replaced manganese steel and other lining plates to become the mainstream of market development.
In addition to protecting the cylinder body, the cylinder liner also has an influence on the movement law of the grinding body. In order to adapt to the requirements of different working conditions (crushing or fine grinding), the shape of the liner material is also different. When smashing is the main requirement, the lining plate should have a strong recommendation ability to the grinding body, and at the same time, the lining plate should have good impact resistance. When fine grinding is mainly used, the protrusion of the lining plate is relatively small. The referral function is weak, the impact is small, and the grinding effect is strong. The lining board is required to have good wear resistance.
⒈High abrasion resistance and impact resistance; The double-dielectric quenched alloy steel liner is scientifically and rationally formulated with alloy elements, so that the liner has good physical and chemical properties, hardness above HRC45-55, impact toughness value above 25J, and service life is high manganese More than twice the steel. Can withstand huge impact. In the work, it can maintain the surface shape of the lining board for a long time to ensure the stable increase of the output of the mill by more than 5%.
⒉High strength and high toughness; in the quenching process of the lining board, the special dual-medium quenching agent with good thermal stability is used as the medium, so that the product achieves the combination of high strength, high hardness and high toughness to meet the wear-resistant process Claim
⒊High cost performance, strong adaptability; after advanced dual-media quenching process, it has the characteristics of high quenching hardness and high toughness value, so that the liner has good wear resistance, compared with high manganese steel liner, medium alloy The alloy steel ball mill liner in dual-media quenching has shown an excellent price-performance ratio. Can adapt to mine wet grinding, dry grinding, mixed grinding, etc.
