This raw material is rarely found in nature, and industrially used magnesia-alumina spinel is all artificially synthesized, and mostly made by the sintering method. The sintering method uses the raw material ratio of industrial alumina or high-purity bauxite and light-burned magnesia, which is ground, mixed evenly, formed into balls, and calcined at a high temperature of more than 1800 °C in a rotary kiln or a shaft kiln.

[0003] A sand making device for producing magnesia-alumina spinel with the publication number of CN220531832U includes a crushing mechanism for preliminarily crushing large-particle-size materials; a sanding mechanism arranged on the discharge side of the crushing mechanism. The sanding mechanism includes a sanding cylinder installed on the discharge side of the crushing mechanism, a cylindrical filter screen coaxially rotated in the sanding cylinder, and a mating shaft coaxially rotated in the cylindrical filter screen; a crushing component arranged on the outer periphery of the mating shaft for crushing the materials in the cylindrical filter screen; and a driving mechanism arranged on the outer side of the sanding cylinder for driving the cylindrical filter screen and the crushing component to rotate coaxially and in opposite directions.

[0004] In the above scheme, although there are many benefits, there are also the following disadvantages: Materials enter the crushing box from the first feed hopper and are crushed by two crushing rollers, then fall on the inclined plane and enter the sanding mechanism through the discharge port for sanding treatment. However, when the materials are fed, some materials will remain on the guide plate arranged at the discharge port, reducing the practicability of the device. Therefore, the sand making device for producing magnesia-alumina spinel is improved and designed. Content of the Utility Model
