Concrete spraying machine, tunnel rotor spraying machine manufacturer

Description :

　　The PZ series concrete spraying machine is mainly composed of a driving device, a rotor assembly, an air duct system, a spraying system, an electrical control box, and other parts. The mixed material is fed into the hopper of the jet machine through a vibrating screen from the discharge port of the batching mixer. It is then moved by the feeder and injected into the direct feeding chamber of the rotor body. It rotates along with the cyclone to the discharge port, where compressed air is introduced from the air chamber to blow the material into the discharge elbow. Here, another compressed air is introduced by the cyclone, which is in a multi head wind spiral state to blow and accelerate the material, causing it to rotate and float. It then enters the feeding pipe and reaches the nozzle, where a small amount of supplementary water or liquid coagulant is added and sprayed out.

　　Operation process of concrete spraying machine: Firstly, cement is pre mixed with water in proportion to form a cement slurry. After mixing evenly, the cement slurry is transported to the cement slurry conveying pipeline through a conveying pump; The sand and gravel mixture is transported by the sand and gravel machine to the sand and gravel conveying pipeline. The cement slurry and sand and gravel are mixed by a specially designed mixer at the last 10 meters and then discharged from the nozzle along the mixing pipeline. Features of the shotcrete machine: 1. Straight through rotor type non bonding material chamber, smooth discharge of concrete shotcrete machine, time-saving; 2. Four point ball compensation compression, good sealing effect, less dust, long service life; 3. Using low-pressure high-speed vortex airflow for conveying, it can solve problems such as material adhesion, pipe blockage, and pulse separation during material conveying, ensuring uniform and continuous material distribution; 4. New nozzle, discharge elbow setting, effect, small rebound, spray layer height;
