[0002] In modern industry, refractory materials are widely used in equipment and structures in high-temperature environments, such as metallurgy, glass, ceramics, and cement. With the development of technology, the market has put forward higher requirements on the performance and quality of refractory materials. Therefore, how to efficiently and accurately produce high-quality refractory materials has become the focus of the industry.

[0003] Traditional refractory material production methods mostly use manual grinding or simple mechanical grinding equipment, which has low efficiency, high energy consumption, and it is difficult to ensure the uniformity and fineness of the material. In addition, when processing large-particle materials, traditional equipment often cannot effectively achieve the connection between initial crushing and subsequent fine grinding, resulting in material waste and increased energy consumption in the production process.

[0004] Therefore, it is very necessary to invent a ball mill for producing refractory materials. Utility Model Content

[0008] Reinforced armor is fixedly installed on the inner wall of the supporting cylinder, and broken ridges are fixedly installed on the surface of the reinforced armor.

[0009] The coarse crushing structure includes a support frame, a hopper, a coarse crushing roller and a crushed material guiding structure, the support frame is located on the ground at one end of the grinding cylinder body, the hopper is fixedly installed on the top of the support frame, and the coarse crushing roller is fixedly installed in the interior of the hopper.

[0010] The two ends of the grinding cylinder body are closed through two end seals, the grinding cylinder body is fed from inside through a reserved hole in the middle of the two end seals, and the grinding cylinder body as a whole rotates through the engagement of a driving gear with external driving structure; the lifting claws are in three groups and are evenly distributed in the interior of the support cylinder body; the reinforcing armors and the breaking beams are in three groups and correspond to the three groups of lifting claws; the lifting claws are upwardly raised to enable the grinding medium balls to drop on the reinforcing armors and the breaking beams only after moving to the topmost end; the reinforcing armors are in three groups of arc-shaped carbon steel metal plates, and the breaking beams are in a plurality of metal protrusions parallel to the axial direction of the grinding cylinder body, which have the following effects: ① increasing collision energy: the steel balls drop only after moving to the highest position, accumulate gravitational potential energy, and convert the gravitational potential energy into kinetic energy when dropping, thereby enhancing the impact force on the material, which can more effectively crush and grind the refractory material; ② optimizing the utilization of grinding medium: the design of the lifting claws enables the steel balls to move up and down in the cylinder body, ensuring that they can impact the material with maximum force when dropping each time, thereby improving the grinding effect; and ③ enhancing the grinding effect: the steel balls impact the material with greater impact force when hitting the reinforcing armors and the breaking beams, and this design not only enhances the grinding efficiency but also effectively reduces the wear of the material on the cylinder body.

[0012] Compared with the prior art, the coarse crushing structure has the following beneficial effects:

[0013] 1. The setting of the grinding cylinder has the following effects: ① increase the collision energy: the steel ball will fall when it moves to the highest point, accumulating gravitational potential energy, which is converted into kinetic energy when it falls, enhancing the impact force on the material, which can more effectively crush and grind refractory materials; ② optimize the use of grinding medium: the design of the lifting claw makes the steel ball move up and down in the cylinder, ensuring that it can impact the material with maximum force every time it falls, improving the grinding effect; ③ enhance the wear effect: when the steel ball hits the reinforced armor and crushing beams, it will produce greater impact force on the material, this design not only enhances the grinding efficiency, but also effectively reduces the wear of the material in the cylinder.

[0014] 2. The setting of the coarse crushing structure has the following effects: ① preliminary crushing: responsible for preliminary crushing of raw materials, reducing large particle materials to a size suitable for further processing in the grinding cylinder, which helps to improve the efficiency of the subsequent grinding process; ② material guiding: through the hopper and the crushed material guiding structure, the coarse crushing structure smoothly transports the crushed material to the inside of the grinding cylinder, ensuring continuous feeding of the material; ③ reduce energy consumption: by preliminary crushing, reducing the particle size of the material, the energy consumption of the subsequent grinding stage can be reduced, because smaller particles are easier to be further ground.
