Casting Grinding Steel Ball for Ball Mill
Application Fields:
Industries of cement building material,metellurgical selection in mine,gringing coal in power
plant,chemical industry and machinery,etc.
Production Process of Steel Ball:
1.The blank used for producing the grinding steel ball is hot-rolled bars with various kinds of chemical
compositons.Its diameter is the same as the nominal diameter of steel balls.
2.Bars are reheated to a proper temperature in a contious furnace before being rolled.
3.After a red hot bar is conveyed into the skew rolling mill,it rotates forward between two rolls with special spiral passes.As this process continous,it is gradually rolled into steel balls.A single skew rolling mill can produce 60-360 steel balls per minute.
4. The hot steel balls are transported directly to the online heat treatment equipment,specially
designed forsteel balls’ quenching and tempering. Steel balls can obtain very high and uniform hardness .
5.Finished steel balls are charaterized by the precise dimension and geometry,better anti-wear properties and mechanical properties.
6.The products which passed inspection are transported to the finished product storehouse and then
delivered to customers after being packed.

FAQ:
1.Q: Can you tell me the key factors which can decide the quality of the grinding balls?
A: They are the raw material, the strict process control,the hardness, the impact toughness, especially the raw material and the heat treatment.
2.Q:Can I see the difference just from the surface of the balls?
A: In general, you can not see the obvious difference from the surface of the balls.
3.Q: How can I make sure you are a reputable supplier?
A: Actually, there is no need to have any doubts about our reputation.High quality products,high
