Description

Technical Field

[0001] This utility model relates to the field of ball mill steel ball technology, and in particular to a high-chromium steel ball for ball mills that is resistant to deformation. Background Technology

[0002] Ball mills are key equipment for further pulverizing materials after they have been crushed. They are widely used in the production of cement, silicate products, new building materials, refractory materials and other industries for dry or wet grinding of various ores and other grindable materials. When grinding ores in a ball mill, wear-resistant steel balls are indispensable. By colliding with the ores, the ores are ground into particles of the required size.

[0003] Existing high-chromium steel balls are prone to plastic deformation under long-term high-speed operation, resulting in irregular shapes. This deformation reduces the effective contact area between the steel ball and the material, thereby significantly reducing grinding efficiency and increasing energy consumption and production time costs. However, due to its integrated design, once plastic deformation occurs during operation due to collisions or other reasons, the entire steel ball must be replaced. Even if the steel ball's shape remains intact, it cannot be specifically repaired, causing many still usable steel balls to be scrapped prematurely, resulting in a huge waste of resources and an increase in production costs.

[0004] Therefore, there is an urgent need to provide a high-chromium steel ball for ball mills that is resistant to deformation to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a high-chromium steel ball for ball mills that is resistant to deformation.

[0006] To solve the above-mentioned technical problems, the present invention provides a high-chromium steel ball for ball mills that is resistant to deformation, comprising a steel ball body, wherein the outer surface of the steel ball body is provided with reinforcing rib grooves and the inner surface of the steel ball body is provided with connecting slots. The top of the steel ball body is fitted with a first outer shell, and the bottom of the steel ball body is fitted with a second outer shell. The top of the second outer shell is fixed with an outer shell insert rod that penetrates and extends into the interior of the first outer shell. The connecting slot is equipped with an assembly mechanism that enhances the steel ball's resistance to deformation. The assembly mechanism is also equipped with a fixing mechanism that allows for targeted repair of the steel ball when it suffers localized damage.

[0007] Through the above technical solution, the first outer shell is spliced ​​with the second outer shell through the outer shell insertion rod, thereby assembling the steel ball body.

[0008] The present invention is further configured such that: the assembly mechanism includes a first reinforcing rib fixed to the inner wall of the second outer shell, a second reinforcing rib fixed to the inner wall of the first outer shell, and the outer sides of the first and second reinforcing ribs are fitted and connected to the inner side of the reinforcing rib slot.

[0009] Through the above technical solution, the second outer shell is connected to the reinforcing rib slot of the steel ball body through the first reinforcing rib, and the first outer shell is connected to the reinforcing rib slot of the steel ball body through the second reinforcing rib, thereby improving the deformation resistance of the steel ball.

[0010] The present invention is further configured such that: a first clamping groove is provided on both sides of the top end of the first outer shell, and a second clamping groove is provided on both sides of the top end of the second outer shell, and a connecting insert is fitted inside the first clamping groove, the second clamping groove and the connecting slot.

[0011] Through the above technical solution, the steel ball body limits and fixes the spliced ​​first and second outer shells through the connecting plug.

[0012] The present invention is further configured such that: one end of the connecting tube is provided with a first internal hexagon head, and the other end of the connecting tube is provided with a second internal hexagon head, wherein the exterior of the first internal hexagon head and the second internal hexagon head are fitted and installed with the interior of the first clamping groove and the second clamping groove.

[0013] Through the above technical solution, the connecting tube clamps and fixes the two sides of the first and second outer shells through the first and second internal hexagon heads.

[0014] The present invention is further configured such that: the fixing mechanism includes a mounting rod fixed to one side of the first internal hexagon head, a first positive and negative limiting block is fixed to the outside of the mounting rod, and a connecting screw is fixed to one end of the mounting rod.

[0015] Through the above technical solution, the first internal hex head is connected to the connecting cylinder through the first positive and negative limiting blocks of the mounting rod.

[0016] The present invention is further configured such that: a connecting screw is fixed to one side of the second internal hexagon head, the interior of the connecting screw is threadedly connected to the exterior of the connecting screw, and a second positive and negative limiting block is fixed to the exterior of the connecting screw.

[0017] Through the above technical solution, the second internal hex head is connected to the connecting cylinder through the second positive and negative limiting blocks of the connecting cylinder, and the connecting cylinder and the connecting screw are threaded together.

[0018] The present invention is further configured such that: a first S-shaped limiting rod is fixed at both ends of the inner wall of the connecting tube, and a second S-shaped limiting rod is fixed at both ends of the inner wall of the connecting tube, and the first S-shaped limiting rod and the second S-shaped limiting rod cooperate to form an S-shaped channel.

[0019] Through the above technical solution, the first and second positive and negative limiting blocks can only enter and exit by repeatedly rotating 90 degrees through the S-shaped channel, which prevents the connecting screw cylinder from becoming loose from the connecting screw rod, thus causing the spliced ​​steel ball to disintegrate directly.

[0020] The beneficial effects of this utility model are as follows: 1. This utility model has a fixing mechanism. The S-shaped limiting rod can limit the front and back limiting blocks. The front and back limiting blocks need to be rotated repeatedly to remove them, which prevents the assembly mechanism from becoming loose. The repairable design allows the steel ball to be repaired when there is local damage, which extends the service life of the steel ball and reduces the waste of resources and increased costs caused by replacing the whole ball. 2. This utility model, by providing an assembly mechanism, can splice and assemble the steel ball and the outer shell. Through a special inner core design, it effectively enhances the steel ball's resistance to deformation and ensures that the outer shell of the steel ball can maintain a good shape during long-term use, thereby increasing the effective contact area with the material and significantly improving the grinding efficiency.
