In addition to protecting the cylinder body, the cylinder liner also has an impact on the movement law of the grinding body. In order to meet the requirements of various working conditions (crushing or fine grinding), the shape and material of the liner are also different.
When pulverization is the main method, the liner should have a good impact resistance to the grinding body. At the same time, the liner should have good impact resistance. The high manganese steel ZGMn13 has sufficient impact resistance, and its surface will be affected by a certain impact. , Most of the mill barrel linings, which are mainly crushed, are made of high manganese steel. When fine grinding is the main method, the protrusion of the liner is relatively small, the pushing effect on the grinding body is weak, the impact is small, and the mechanism of grinding action. The liner is required to have good wear resistance. The material of the mill barrel lining board mainly for fine grinding is usually wear-resistant white iron, chilled cast iron, medium manganese rare earth ductile iron, etc.
The ball mill liner is used to protect the cylinder from the direct impact and friction of the grinding body and the material. At the same time, different forms of liner can be used to adjust the movement state of the grinding body to enhance the grinding effect of the grinding body on the material, improve the grinding efficiency of the mill, increase the output, and reduce the metal consumption. The cylinder liner not only protects the cylinder body, but also has an impact on the movement law of the grinding body. The special dual-medium quenching agent with good thermal stability is used as the medium to make the product achieve high strength, high hardness and high toughness. Process requirements for wear resistance. Characteristics of alloy steel ball mill liner in dual-medium quenching: high wear resistance, impact resistance, high strength, high toughness, cost-effective, and strong adaptability. After advanced dual-medium quenching process, it has high quenching hardness and high toughness. The characteristics make the liner have good wear resistance. It can adapt to mine wet grinding, dry grinding, mixed grinding, etc.
