Cement yield increasing and consumption reducing device based on solid waste efficient utilization

The utility model discloses a cement yield-increasing and consumption-reducing device based on efficient utilization of solid waste, which comprises a cement grinding bin, a feeding mechanism is arranged on one side of the cement grinding bin, a feeding port is arranged above the feeding mechanism, a first feeding plate which is transversely arranged is fixed in the feeding port, and a second feeding plate which is transversely arranged is fixed in the first feeding plate. A second feeding plate abuts against the lower portion of the first feeding plate, a plurality of sets of first screening holes and second screening holes are evenly formed in the first feeding plate and the second feeding plate respectively, and a driving mechanism used for driving the second feeding plate to do left-right reciprocating motion below the first feeding plate is arranged on one side of the second feeding plate. The feeding speed of solid waste can be controlled, the discharging speed of the solid waste can be reduced, the amo
