Ball mill liner helps to improve the grinding efficiency of the mill
The ball mill liner is used to protect the cylinder from the direct impact and friction of the grinding body and material. At the same time, different forms of liners can also be used to adjust the motion state of the grinding body, so as to enhance the grinding effect of the grinding body on the material. It helps to improve the grinding efficiency of the grinder, increase the output, and reduce metal consumption.

It helps to improve the grinding efficiency of the grinder, increase the output, and reduce metal consumption.
The lining plate of the ball mill is gradually replaced by medium alloy steel lining plate, but with the continuous application of medium alloy steel lining plate in the ball mill lining plate, it has gradually replaced manganese steel and other lining plate to become the mainstream of market development.
In addition to the protection of the cylinder, the liner also has an impact on the movement of the grinding body. In order to meet the requirements of various working conditions (crushing or fine grinding), the shape of the liner is also different. When the grinding is given priority to, the lining plate is required to have a strong pushing ability to the grinding body, and the lining plate should have good impact resistance. When the fine grinding is given priority to, the protrusion of the lining plate is relatively small, and the pushing effect on the grinding body is weak, the impact is small, and the grinding effect is strong. The lining plate is required to have good wear resistance.
High wear resistance, impact resistance
Double medium quenching medium alloy steel lining plate by scientific and reasonable alloy element formula, so that the lining plate has good physical and chemical properties, hardness of more than HRC45-55, impact toughness value of more than 25J, service life is more than 2 times of high manganese steel. Able to withstand huge shocks. The surface shape of the liner can be maintained for a long time in the work to ensure that the mill can stably increase the output by more than 5.
The high strength, high toughness
In the quenching process of the lining plate, the special dual-medium quenching agent with good thermal stability is used as the medium, so that the product can achieve the combination of high strength, high hardness and high toughness, so as to meet the process requirements of wear resistance.
3. High cost performance, strong adaptability
After the double medium quenching process, it has the characteristics of high quenching hardness and high toughness value, so that the lining plate has good wear resistance, compared with the high manganese steel lining plate, the medium alloy double medium quenching medium alloy steel ball mill lining plate shows the cost performance. Can adapt to the mine wet grinding, dry grinding, mixing mill, etc.
