There are four types of wear-resistant steel balls: one is white cast iron with chromium as the main alloying element, referred to as chromium alloy cast iron, and the cast grinding ball made of chromium alloy cast iron is called chromium alloy cast iron grinding ball; the second is cast grinding ball made of ductile iron, referred to as ductile iron grinding ball, among which the matrix structure obtained by heat treatment is mainly bainite, referred to as bainite ductile iron grinding ball; the matrix structure obtained by heat treatment is mainly martensite, referred to as martensite ductile iron grinding ball; the third is the steel ball made of round steel produced by steel mills, which is hot-rolled, with full process automation control, uniform hardness, high core hardness, low crushing rate, and large impact value of steel balls; the fourth is forged with train wheel blanks, which has low cost, but low core hardness, easy to break, and poor wear resistance.
[0003] Grinding steel balls are an important part of grinding equipment and are widely used in the grinding process of materials in the chemical, pharmaceutical, food and other industries. Traditional grinding steel balls are easily deformed and broken due to the pressure and impact from the materials and related components inside the grinder during use. At the same time, they will cause varying degrees of excessive wear as the use time increases, and their service life is short, which cannot meet the long-term and efficient grinding needs. Therefore, it is necessary to design a multifunctional grinding steel ball with high wear resistance to improve grinding efficiency and service life and reduce production costs.

[0010] Preferably, the reinforcing ribs are arranged irregularly in the steel ball body.
[0011] Preferably, the steel ball body is made of high-strength alloy steel and is subjected to heat treatment and surface treatment technology.
[0012] The beneficial effects of the utility model are:
[0013] The utility model has a reasonable design and a simple structure and has high wear resistance, high pressure resistance and high corrosion resistance and is suitable for grinding operations in different environments. By opening a plurality of grinding grooves on a steel ball body made of a highly wear-resistant material, the contact area between the grinding steel ball and the material is increased, thereby improving the grinding efficiency. At the same time, the provision of the anti-corrosion coating can effectively prevent the steel ball body from rusting in a humid environment, thereby further extending the service life of the grinding steel ball.
[0014] In addition, by setting a plurality of irregularly arranged reinforcing ribs inside the steel ball body, the compressive performance of the steel ball body can be effectively improved to prevent deformation or breakage during the grinding process. The steel ball body is made of high-strength alloy steel, and through heat treatment process and surface treatment technology, it has high wear resistance, high compressive resistance and high corrosion resistance, which meets the grinding needs in different environments.
