The three rollers of the machine are made of the cold hard alloy material and are grinded on the special convex abrasive machine, so that the effective working surface of the rollers are slightly convex. Because the rollers expand with heat and contract with cold, in the process of grinding the machine has automatic compensation to extend the service life, as well as increases the grinding efficiency and fineness.

    In accordance with the original fineness, hardness,and toughness,materials can be grinded once, twice or more times ,and ultimately to achieve the required fineness (generally about 3-18 microns , determined by the fineness board).
