[0022] Grinding mechanism 9: arranged at the lower end of the inner part of the housing 1, the grinding mechanism 9 comprises a rotating column 91, a conical grinding ring 92 and a fixed grinding ring 93. The rotating column 91 is rotatably connected to the rotating hole in the middle of the support plate 5. The upper end of the rotating column 91 is connected to the conical grinding ring 92 through a cross plate. The fixed grinding ring 93 is arranged at the lower end of the inner arc surface of the housing 1. The conical grinding ring 92 and the fixed grinding ring 93 are installed in coordination. The rotating column 91 drives the conical grinding ring 92 to rotate, so that the conical grinding ring 92 and the fixed grinding ring 93 rotate relatively. At the same time, the conical grinding ring 92 and The spacing of the fixed grinding ring 93 gradually decreases from top to bottom, and the refractory between the conical grinding ring 92 and the fixed grinding ring 93 is ground. The grinding mechanism 9 also includes a fixed die plate 94, a blowing hole 95 and a grinding roller 96. The fixed die plate 94 is arranged on the upper surface of the support plate 5, and the surface of the fixed die plate 94 is respectively provided with blowing holes 95. The grinding roller 96 is respectively connected between the outer arc surface of the rotating column 91 and the inner arc surface of the conical grinding ring 92 through a rotating shaft. The grinding roller 96 is installed in cooperation with the fixed die plate 94, and the grinding roller 96 moves with the rotating column 91 and The conical grinding ring 92 rotates together, and the distance between the grinding roller 96 and the upper surface of the fixed die plate 94 becomes smaller as it approaches the rotating column 91.

The grinding mechanism 9 also includes a scraper 97, which is arranged between the outer arc surface of the rotating column 91 and the inner arc surface of the conical grinding ring 92. The scraper 97 fits the upper surface of the fixed die plate 94 to push and scrape the refractory material on the surface of the fixed die plate 94, so that the ground refractory material enters the inside of the blowing hole 95 and is accurately blown. The flow carries the refractory material upward, and the grinding mechanism 9 also includes a motor 98. The motor 98 is arranged on the lower surface of the air inlet pipe 4. The upper end of the output shaft of the motor 98 is fixedly connected to the rotating column 91.

The upper end of the conical grinding ring 92 is provided with an inverted cone ring 11 to guide the falling trajectory of the unqualified refractory material filtered out by the filter plate 7.

[0023] The working principle of a refractory grinding mill provided by the utility model is as follows: when in use, the refractory material is poured into the shell 1 through the feed pipe 3, and the refractory material enters between the conical grinding ring 92 and the fixed grinding ring 93. The motor 98 is started by the single-chip microcomputer 10, and the output shaft of the motor 98 drives the rotating column 91 and the conical grinding ring 92 to rotate. The refractory material is ground by the cooperation of the conical grinding ring 92 and the fixed grinding ring 93. The distance between the conical grinding ring 92 and the fixed grinding ring 93 gradually decreases from top to bottom, so that the particle size of the refractory material becomes smaller and smaller. When the refractory material leaves between the conical grinding ring 92 and the fixed grinding ring 93 and falls to the surface of the fixed mold plate 94, the refractory material is guided by the conical upper surface of the fixed mold plate 94 to move closer to the rotating column 91. The grinding roller 96 moves in the direction of the rotating column 91. During the movement, the grinding roller 96 rotates with the rotating column 91 and the conical grinding ring 92. The closer to the rotating column 91, the smaller the distance between the grinding roller 96 and the upper surface of the fixed mold plate 94 is. Through the cooperation of the grinding roller 96 and the fixed mold plate 94, the refractory material is ground twice. During the grinding process, the electric fan 6 is started to provide power for the flow of air, so that the external air enters the air inlet pipe 4. Under the guidance of the planar spiral-shaped guide plate 8, the air flow evenly passes through the pores on the surface of the support plate 5, and is finally blown out from the blowing hole 95. The refractory material on the surface of the fixed mold plate 94 is pushed and scraped by the rotation of the scraper 97, so that the refractory material is accurately carried upward by the air flow and discharged from the discharge pipe 2 after being filtered by the filter plate 7.
