High cost performance, strong adaptability:

The high manganese steel liner is processed by advanced technology. It has the characteristics of high quenching hardness and high toughness value, so that the high manganese steel liner has good wear resistance. Compared with the ordinary liner, the high manganese steel liner performs Outstanding price-performance ratio. It can adapt to mine wet grinding, dry grinding, mixed grinding, etc.
