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.
Main Prodcts:
1.Forged steel grinding ball
2.Rolled steel grinding ball
3.Cast iron balls
4.Grinding rods
5.Grinding cylpebs
6.Mill liner
7.Various kinds of steel flanges
