This utility model relates to the field of cement raw material grading technology and discloses a raw material grading device for cement processing. An installation mechanism is provided on the processing box and the guide box plate. A grading mechanism is provided on the processing box and the collection box. The grading mechanism includes a screening component and a fixing component. The screening component includes an annular chute. The left and right rotating shafts of the motor are fixedly connected. Fixing blocks are fixedly connected to the left and right surfaces of the filter cover, and an arc-shaped plate is fixedly connected to the back of the fixing blocks. U-shaped seats are fixedly connected to the left and right surfaces of the filter cylinder. In this raw material grading device for cement processing, the insert block is inserted into the slot, and the long block is inserted into the long groove. A relay controls two electric push rods to start simultaneously. Under the operation of the electric push rods, the limiting block is driven to insert into the limiting groove, which can fix the guide box plate on the top of the processing box and cover the top cover of the guide box plate, preventing cement dust from overflowing during cement raw material screening.
