10mm 25mm 125mm 180mm Ball Mill Grinding Media Price Forged Steel Grinding Ball for Mine and Cement Power Plant
Product Description:
Zhongwei is able to manufacture accurate-size, high-roundness,high-hard rolling balls. They have great wear resistance, difficult deformation and less broken, uniform hardness distribution, high impact toughness( over 12j/cm2). Mainly suitable for industries such as mining, steel, chemical industry, cement plants, power plants, ball coal machine, semi-automatic ball mills, and ball mills,etc.
Round alloy steel bar material after passing the inspection, product according to the size of the steel ball . The steel forging is heated to a certain temperature by intermediate frequency furnace to ensure the effective generation of variables in the forging; The red-hot steel forging is sent into the air hammer and processed by skilled operators. After forging the red hot steel ball immediately into specially designed heat treatment equipment for quenching and tempering heat treatment, this can made the steel ball have high and uniform hardness value.

Production Line:
1.The materials of the grinding steel balls is different grade round steel bars with various chemical composition.
2. The round bars are heated to a proper temperature in a continuous s furnace before rolling.
3. Red hot bar is conveyed into the skew rolling mill,then it rotate es forward between two rolls with special spiral 7L.As this process continues, it is gradually rolled into steel balls.A single skew rolling m hill can produce 60-200 steel balls per minute.
4.The red hot steel balls are transported directly to the online heat treatment equipment, which is specially designed for quenching and tempering.This makes sure steel balls can obtain high and uniform hardness.
2) Auto Hot Rolling
Raw material →Hot Rolling Mill → Water Quenching → Tempering
