[0002] In daily life and in the process of industrial development, refractory materials play a crucial role. From high-temperature furnace linings in steel smelting to internal components of glass manufacturing furnaces and kiln furniture for ceramic firing, refractory materials are key basic materials for ensuring the continuity and stability of production due to their excellent high-temperature resistance and erosion resistance. However, the performance of refractory materials largely depends on the crushing process in their production.
[0003] The crushing device for refractory material production consists of a feeding hopper, a feeding conveyor belt, a crushing chamber, a crusher, and a screen. The raw material is fed into the crushing chamber from the feeding hopper via the conveyor belt. The motor drives the crusher to crush the material. The crushed material falls onto the screen, and qualified particles are discharged from the outlet under vibration.

[0032] Working principle: Refractory material is fed into the equipment through the feed port 2 at the top of the outer shell 1. The motor 301 drives the transmission shaft 304 to rotate. The rotation of the transmission shaft 304 drives the transmission gear 307. The transmission gear 307 and the follower gear 303 mesh, thereby driving the follower gear 303 to rotate. The follower gear 303 drives the rotating shaft 302 and the crushing column 305 to rotate. When the crushing column 305 rotates, it drives the meshing teeth 306 to rotate. The two meshing teeth 306 mesh to initially crush the refractory material. It is then screened by the screening mechanism 4. The unqualified material enters the grinding frame 3010. At the same time, the motor 308 drives the rotating disk 309 to rotate, and the connecting column 3011 also rotates. Simultaneously, the grinding column 3012 slides on the inner bottom circumference of the grinding frame 3010 to further crush the unqualified refractory material, making the crushing more comprehensive.
[0033] After initial crushing, the motor 404 connected to the outside of the fixing strip 403 drives the rotating column 405 to rotate, which in turn drives the transmission ring 406 to rotate. When the transmission ring 406 rotates, it pulls the linkage rod 407. When the linkage rod 407 is pulled, the other end pulls the sliding block 408, which in turn pulls the push column 409. The push column 409 pulls the filter screen plate 402, which is limited by the connecting column 401, to shake up and down to screen the refractory material. At the same time, the elastic action of the rebound spring 4011, which is limited by the limiting column 4010, makes the shaking more intense. A lot of dust is generated during the screening and shaking. The dust is then blown by the fan 8 along the pipe inside the outer shell 1 through the primary filtration of the filter plate 6 and the secondary filtration of the filter plate 7, purifying the internal air and discharging it from the exhaust port 5.
