The position of the screen frame 17 corresponds to the position of the weighing box 1. A round rod 6 is rotatably connected to the inside of the weighing box 1 through a bearing. The maximum distance between the center of the round rod 6 and the collection box 9 is less than the minimum distance between the center of the round rod 6 and the blanking funnel 3. The position of the blanking funnel 3 corresponds to the position of the collection box 9. The end of the round rod 6 is fixedly connected to the output end of the second servo motor 19. The first electro-hydraulic push rod 4, the second electro-hydraulic push rod 12, the weighing instrument 8, the first servo motor 14 and the second servo motor 19 are all electrically connected to an external power source through wires. A matching block 7 is installed on the outer surface of the round rod 6, a weighing instrument 8 is installed on the top of the matching block 7, a collection box 9 is installed on the top of the weighing instrument 8, a positioning cylinder 10 is installed on one side of the weighing instrument 8, a cavity frame 11 is installed on one side of the blanking funnel 3, a second electro-hydraulic push rod 12 is installed on the inner wall of the cavity frame 11, a baffle 13 is installed at the movable end of the second electro-hydraulic push rod 12, and the end of the baffle 13 away from the second electro-hydraulic push rod 12 abuts against the inner wall of the blanking funnel 3. The position of the blanking funnel 3 is higher than the position of the first electro-hydraulic push rod 4.

[0027] During use, first screen the raw material alumina-cryolite. After screening, the qualified raw material alumina-cryolite falls into the inside of the blanking funnel in the weighing box.
