The double-rotor sand making machine is a sand making equipment specially developed by our company according to the current situation of domestic sand making machines and the actual production situation, as well as the lack of natural sand resources in my country. It has simple structure, stable operation and high crushing efficiency. , Superior performance with less power consumption. It is mainly used for the production of artificial sand and the use of waste concrete, waste lime, and other waste residues to prepare machine-made sand. It not only solves the shortage of sand and gravel aggregate supply and the problem of skyrocketing prices caused by the shortage of natural yellow sand resources, but also provides national high-level High-quality sand and gravel aggregates are provided in many fields such as construction, highway, railway construction, municipal engineering, large-scale water conservancy facilities, and concrete mixing. This equipment not only has low sand making cost, but also has high environmental protection benefits, and has been widely recognized by many users.
100% product on-site real shooting, so you can rest assured of your choice!
The materials in the crushing cavity are thrown out along the tangential direction by the two rotors, forming repeated high-speed collisions and crushing, with large crushing ratio and high output.
The overall grate plate of the equipment adopts a rubber damping system to ensure the smooth operation of the equipment during work.
The aggregates crushed by this equipment have uniform particle shape, good particle shape, continuous gradation, adjustable fineness modulus, and its particle shape and particle size can be compared with natural sand.
The hydraulic opening device is adopted, which is safe in operation and convenient in maintenance. The manual observation door under the double rotor is convenient for timely cleaning when the material is blocked, which is convenient for inspection and maintenance. At the same time, it is more convenient and quick to replace the hammer head, which effectively improves the work efficiency.
The equipment is mainly composed of the machine body, crushing plate, upper rotor, lower rotor, pendulum, rotating drive device, sieve plate, etc. During the working process of the machine, the two rotors run relative to each other. The hammer hits the second rotor after hitting and crushing and obtains the kinetic energy. Since the second rotor is opposite to the direction of the material flying, the second rotor’s impact speed on the material is equal to the superposition of the two speeds. After being broken by so many cycles, it is discharged through the gap of the grate.
