Therefore use high manganese steel slag Raymond grinding milling roller and grinding ring material, to adapt to the steel slag grinding characteristics, has made a good technical effect.

Author used laser beam to quench the surface of the ore milling roller, so that increase its surface hardness and improve its wear resistance properties, and prolong its service life.

For many years mill practice has shown that adoption of non-grooving roller in last rill can obviously increase the efficiency of milling.
