How to choose grinding steel balls

1. Good machining performance

Grinding steel balls must be processed and drilled on the surface before use so that they can be accurately assembled on the mill for normal work. Therefore, good machining performance is a basic requirement for the ball plate casting blank.

2. Uniform internal organization and hardness distribution

Uniform internal structure and hardness distribution are important properties of steel ball quality and steel ball life.

3. No casting defects

During the processing and use of rough castings, there should be no defects such as sand holes, pores, hard spots, slag inclusions, and looseness. Otherwise, the service life of the grinding steel ball will be shortened, and more importantly, the surface of the steel ball will be scratched and damaged.

4. Excellent wear resistance

The main damage form of the grinding steel ball is friction and wear, so the wear resistance of the grinding steel ball is the main factor that determines the life of the grinding steel ball.

5. Larger mechanical strength

In addition to wear, the grinding steel ball is also subject to impact at certain points, so the mechanical strength is also the performance index of the grinding steel ball.
