Advantages of mining machinery parts
1. Long service life, light weight, thin thickness, low ball and power consumption.
2. Fast replacement and maintenance, easily installed and need less labor work .
3. Widely used for high, medium, and weak magnetic mineral.
4. Attached on the inner wall of cylinder by magnetic force, no pulp leakage and highly efficient.
5. Can be used for nonmagnetic mineral substance, but certain quantity of ferromagnetic substances such as broken steel balls and scrap iron must be added form protection layer.
It is used for sand rock crushing, broken grog material of cement works; the broken of cobble and mineral ore of non-ferrous and other material of poor easy-destructive
