Why should manganese steel screen be used in mines?

Why manganese steel screen is used in mines? First of all, we should understand the material characteristics of manganese steel, its high wear resistance and ductility are good, and the screening rate is high, the cost performance is also higher.
The ordinary screen is worn too fast in the mine, and it will be replaced in a few days. It is troublesome to replace the screen of mine equipment. Frequent replacement of the screen will delay the mining progress; a lot of time is wasted in replacing the screen screen.
If the use of higher wear-resistant polyurethane products, although wear-resistant, but the screening rate is relatively low, screening efficiency will reduce the cost will increase a lot, and for many mines, the price of polyurethane screen is not very acceptable.
For their own screening material hardness, production tasks and production cost budget, to determine the kind of material they need, more reasonable, maximum benefit.
