Chromium oxide powder classifying and filling device

The utility model discloses a chromium oxide powder classifying and filling device. The utility model discloses a chromium oxide powder filling device. Manual loading into a hand-push trolley is needed; filling after re-classification, filling incapable of directly classifying, on one hand, the labor intensity of workers is increased, on the other hand, the enterprise cost is increased. The feeding device comprises a hopper, a support, a control panel, a rotating mechanism, an inclined pipe, a ball valve, a stock bin pipe, a switch box, a material pipe, a discharging hole, a stop block groove,an electric push rod, a stop block and a limiting block. A bracket is mounted in the middle of the hopper; a control panel is mounted at the top of one side of the bracket; a rotating mechanism is mounted at the bottom end of the hopper; the chromium oxide powder filling machine has the advantages that the structure is novel, the conception is ingenious, different types of chromium oxide powder products can be subjected
