Description
Our Advantages
The production process is using the upset forging and rotary forging. The balls' undergoes the heat treatment of one quench and twice temper. As a result, the grinding balls 146mm has a better inner structure and density to improve the grinding efficiency and reduce the grinding balls consumption.
QUALITY CONTROL
1. Measurement of mass and density of incoming steel bars
2. Chemical analysis of incoming steel bars
3. Manufacture 10 pcs of balls for evaluation of surface and volumetric hardness
4. Evaluate dimensions and roundness of balls
5. Monitor hardness, dimensions and roundness electronically during production
6. Balls heat treatment before packing
7. Final evaluation of hardness, dimensions and roundness before packing
