What are the classifications of steel balls?

From the perspective of application categories, steel balls can be divided into two categories: wear-resistant steel balls used in the crushing industry and bearing steel balls used in the precision bearing industry. Wear-resistant steel balls (referred to as grinding balls) are the most widely used products in industrial practice today. There is a saying that goes: "If there is industry, there must be crushing", which is very appropriate; Bearing steel balls have a long history of use in the precision bearing industry and daily life, and are more widely used. It can be said that steel balls exist in most places where there is rotation, commonly known as steel balls or rolling balls. Steel ball is a general term for steel ball, steel segment, and irregular grinding body. From the perspective of appearance, it can be divided into regular round balls (commonly referred to in a narrow sense), capsule balls, elliptical balls, yin-yang balls, hollow balls, polyhedral balls, and polyhedral balls (with pits on the surface).

The production methods of steel balls generally include forging, rolling, semi solid forming, and casting. Due to the special usage conditions, comprehensive environment, and background of history and mineral processing industry, forging and rolling balls account for a considerable proportion in these industries. Semi solid forming has the characteristics of unconventional casting, which cannot be explained by simple die casting. It has attracted people's attention due to its excellent performance formed by an advanced technology that combines the advantages of casting, forging, and forging. Casting steel balls, on the other hand, have the advantages of simple, flexible, and reliable production methods, making it easy to achieve low investment and large-scale production expansion. Especially when experts and engineers face the use of various advanced processes and alloy composition designs in steelmaking furnaces, they unleash endless imagination to create one more novel and advanced variety after another, to meet the sense of achievement brought by competitive needs, which is even more impressive. Of course, the high cost-effectiveness and sustainable development potential of ball casting make it the main force in today's crushing industry, especially in the production of steel balls in the cement crushing industry.
Commonly used cast steel balls can be roughly divided into the following eleven categories based on their chemical composition:
1. Chromium series wear-resistant cast iron balls;
2. Low alloy steel wear-resistant cast ball;
3. Medium high alloy steel wear-resistant cast ball;
4. High manganese steel balls;
5. Half steel and half iron ball;
6. Medium manganese ductile iron balls;
7. Obe and Mabe duplex steel balls;
8. BAD, CAD wear-resistant cast balls;
9. Special alloy cast iron balls;
10. Anti wet wear cast ball;
11. Other cast balls.
