Waterproof pulverization grinder

A grinder adopting waterproof pulverization comprises a frame. A motor and a bearing seat are arranged on the frame, the bearing support is connected with a casing, a main shaft supported by a bearing is mounted on the bearing support, and the main shaft is connected with the motor through a coupling. The grinder is characterized in that a rotor and a booster impeller are arranged on the main shaft, a mechanical sealing device is arranged at one end of the main shaft in a position near the motor, a stator and a rotary regulating piece are mounted on the casing, a discharge opening is formed on the casing, an inlet cover plate is mounted on the stator, a feed opening is formed on the inlet cover plate, both the rotor and the stator adopt a cone-shaped structure, and grinding teeth are formed on the working surfaces of the rotor and the stator. The grinder adopting waterproof pulverization can not cause contamination to the material and has high productivity, and is applicable to material with high viscosity an
