It is especially suitable for the fine crushing of water-containing, large-mud content and cohesive materials. The rear frame and the lower frame body of the utility model adopt a hinged form, and are equipped with a screw rod or a hydraulic opening and closing mechanism, which can be turned over at a certain angle, and are convenient for replacing the toothed lining plate and the rotor blow bar. The two bearing seats of the rotor body are outside the body and do not directly contact with the material, so it can process hot material below 100°C. The motor and the rotor of the crusher adopt the transmission mode of large and small pulleys and V-belts. The rotor speed can be adjusted according to the properties of different materials and the requirements of finished products. When overloaded, the V-belt slips to protect the motor from damage. The transmission motor is arranged in various forms and occupies a small space. The blow bar and blow bar seat are arranged in a staggered manner on the rotor body to ensure that the material and the blow bar can produce positive impact in both axial and circumferential directions. The blow bar is made of wear-resistant material, and the blow bar seat is made of cast steel with high tensile strength, which not only ensures the wear resistance of the blow bar, but also ensures the safety and reliability of the blow bar seat. To replace the blow bar, you only need to remove the fixing bolts between the two, without removing the pin shaft and the blow bar seat. The blow bar and the blow bar seat are hinged relative to the rotor body and can rotate at an angle to prevent small unbreakable objects from entering and damaging the main engine.
