Ball Mill Liner

Materials Of Ball Mill Liner

Common materials for ball mill liners include high manganese steel, chrome steel, hard steel, alloy steel, rounded square liners, rubber liners and magnetic liners.

Because of its good toughness and good work hardening properties, high manganese steel linings once occupied the dominant position of mill linings, but it is also accompanied by shortcomings such as easy deformation, high steel consumption, high cost and low efficiency. Therefore, high manganese steel has withdrawn from the mill liner market in a decreasing trend year by year.

At present, mainstream linings include rubber linings and alloy steel linings. The alloy steel lining plate is wear-resistant and impact-resistant, and the reasonable alloy element formula makes the lining plate have good physical and chemical properties, and its service life is more than twice that of high-manganese steel.

High wear resistance and impact resistance

The alloy steel lining plate in double medium quenching has a scientific and reasonable alloy element formula, so the lining plate has good physical and chemical properties. It Can withstand huge shocks. The surface shape of the lining plate can be maintained for a long time during the work to ensure that the mill can steadily increase the output by more than 5%.

High strength, high toughness

In the quenching process of the lining plate, a special dual-media 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 technological requirements of wear resistance.

Cost-effective and strong adaptability

After being treated by the advanced dual medium quenching process, it has the characteristics of high quenching hardness and high toughness value, which makes the lining plate have good wear resistance. Compared with the high manganese steel lining plate, the medium alloy double medium quenching medium alloy steel ball mill lining board exhibits an excellent price/performance ratio. Can adapt to mine wet grinding, dry grinding, mixed grinding, etc.
