This series of products is a new type of sand making equipment developed by our company according to the use status of sand making machine equipment at home and abroad, combined with the feedback and suggestions of users on the use of problems, and through optimized design.  It has the characteristics of large impact force, large crushing ratio, simple structure, stable operation, high output and low energy consumption, etc., and has been recognized and favored by many users.  

1. Open and close from the center of the rotor, using hydraulic ejection opening, more convenient and quick replacement of parts, improve work efficiency;  

2. Rubber spring is adopted to absorb the shock of the overall assembly structure to ensure the smooth operation of the equipment;  

3. The pump station can be moved away from the dust area at any time by adopting the quick adapter, effectively prolonging the service life;  

4. There is an observation door under the two rotors, which can plug and inspect the grate quickly and effectively reduce the equipment maintenance time;  

5. The finished aggregate has excellent shape, continuous gradation and adjustable fineness modulus. Its grain shape can be comparable with natural sand.  

CSJ double-rotor sand making machine is mainly composed of machine body, crushing plate, upper rotor, lower rotor, pendulum, rotary driving device, sieve plate, etc. The two rotors of the double-rotor sand making machine work relatively during the working process and enter the crushing cavity The material of the first is crushed by the hammer head on the rotor and the kinetic energy obtained hits the second rotor. Since the second rotor is in the opposite direction to the material, the speed of the second rotor against the material is equal to With the superimposition of the two speeds, the material will be broken through the gaps of the grate after being broken by so many cycles.
