Plastic particle grinding machine

The utility model discloses a plastic particle grinding machine. The plastic particle grinding machine comprises a bracket and a grinding machine main body mounted on the bracket, wherein the grinding machine main body comprises a housing, grinding slurry in the housing and a motor for driving the grinding slurry; a charge end of the grinding machine main body is connected with a discharge hole pipeline of a turbine b; a material collecting tank is mounted at a charge hole of the turbine b; a material sucking device is mounted on the material collecting tank; a hose is mounted at the charge hole of the material sucking device; the other end of the hose is connected with a raw material barrel; a buffer valve is mounted at a discharge end of the grinding machine main body; a waste material end of the grinding machine main body is connected with a charge end of the turbine a; a discharge end of the turbine a is connected with a waste material tank. According to the plastic particle grinding machine, the equipment is improved, the materials are sucked into the material collecting tank through the material sucking device, and the materials are punched into the grinding machine main body through the turbine b for being grinded, and the grinded materials are classified so as to enter the waste material tank and a finished product region, so that the whole process is operated by the equipment, no material scatters, staff only needs to observe the equipment operation condition and the labor intensity is lowered.
