Description

Technical Field

[0001] The utility model relates to the technical field of wear-resistant steel balls, in particular to a high-strength wear-resistant steel ball. Background Art

[0002] Wear-resistant steel balls, also known as wear-resistant media for grinders, are a type of crushing media used in ball mills. Their main purpose is to grind materials to a finer particle size to meet use requirements. Wear-resistant steel balls are widely used in mines, power plants, cement plants, steel plants, silica sand plants, coal chemical industry and other fields.

[0003] A Chinese patent discloses a high-strength wear-resistant steel ball (authorization announcement number CN219502886U). This patented technology solves the problem of poor grinding effect of existing wear-resistant steel balls. Before use, you can hold the lower shell and the upper shell with both hands, and use both hands to apply force in opposite directions. The grinding sand inside the lower shell and the upper shell can be used to grind the ball for a second time, so that the surface of the ball is smoother, thereby making the subsequent use effect better. At the same time, during use, when it is found that the surface of the ball is damaged or rough, the outer shell and the upper shell can also be used to grind it, thereby increasing the grinding effect while saving costs.

[0004] However, there are still some shortcomings in this patent. Although the patent can strengthen the steel ball, it can be seen from the drawings of the patent that the ball of the patent is an integrated design. In this way, if the steel ball is damaged during use, it needs to be replaced as a whole, resulting in increased costs. Therefore, those skilled in the art provide a high-strength wear-resistant steel ball to solve the problems raised in the above background technology. Utility Model Content
