[0030] The working principle is as follows: this device sets a crushing component, and uses gear 19 to drive two crushing spiral rollers 20 at different positions to cooperate with the grinding screen plate 28. It can not only grind large-particle raw materials by extrusion, but also screen them through the grinding screen plate 28 to ensure that the product quality in the final mixing box is qualified. By setting a mixing and conveying structure, the screened raw materials enter the storage hopper 11, and then are driven by the shaft column 24. The scraper paddle 25 in the storage hopper 11 performs preliminary stirring on them, and then they are conveyed to the mixing box 10 through the feeding screw 26, and finally mixed by the mixing paddle 27.
