[0031] Through the above structure, the mineral powder raw materials are ground and crushed by two groups of grinding rollers 4, and the crushed mineral powder raw materials fall to the bottom of the grinding box 1. The motor 10 drives the feeding auger 11 to rotate, and the crushed mineral powder raw materials are transported by the feeding auger 11 and fall into the discharge trough 8 for discharge. The material on the inner wall of the discharge pipe 7 is scraped by the feeding auger 11, and the scraper 12 is driven by the feeding auger 11 to scrape the material on the inner wall of the bottom of the grinding box 1;

[0032] Gas is fed into the base rod of the telescopic rod 16 through the pump body 19 to push out the extension rod, and the push plate 17 is pushed downward by the extension rod of the telescopic rod 16, and the material is pushed downward by the push plate 17, so that the material is squeezed between the push plate 17 and the two groups of grinding rollers 4, and the material can be squeezed and ground by the rotation of the grinding rollers 4 to prevent the material from sliding on the upper side of the two groups of grinding rollers 4. The specific structure is as follows:

[0033] Combined with Figure 1 and attached Figure 3 As shown, the two axial ends of the grinding roller 4 are rotatably connected to the side walls of the grinding box 1 respectively, and a group of motors 5 connected to the grinding roller 4 are installed on the outer wall of one side of the grinding box 1.
