In the production of cement, powdered raw materials need to be screened, and thus a powder selection device is needed;

[0003] The existing patent discloses a powder selection device for cement production with multi-stage screening (publication number: CN216322118U). During use, the powder raw materials screened can be guaranteed to be qualified, and unqualified powder raw materials can be prevented from being transported to the grinding device for processing, thereby improving the working efficiency of the powder selection device, reducing the production time, ensuring the working efficiency of the through holes, and preventing the through holes from being blocked and unable to be screened. However, when the crushing block crushes the cement raw materials on the fixed plate, some qualified powder falls from the through holes, but powder still remains at the position where there is no through hole at the upper end of the fixed plate, and it is impossible to drop it onto the screening plate in time, thereby easily wasting raw materials and further reducing the powder selection efficiency. For this reason, the utility model proposes an efficient powder selection device for cement production. Utility Model Content
