Technical feature
1. Through type rotary, non-sticky, unobstructed discharge, high efficiency and time-saving.
2. Four-point clamping device makes it easy to adjust the press between sealing plate and rotor disk so as to reduce air and dust leak and prolong consumption parts life.,
3. Using low-tension, high-speed vortex pneumatic transportation, so the spraying flow is even, continuous and steady. It's good to improve the shotcrete quality.
4. The new nozzle, discharge elbow device, improving spray deposition effect, less resilient, high quality shotcrete.
5. The machine chassis can be assembled into wheel-type, skid-type and various gauge rail wheel.
Working principle
The stirred material from the mixer discharge port fed into the jet through the vibrating screen hopper, then injected into the straight chamber of the rotor by kick-out device and then turn to the discharge port with the rain of of the cyclone. At this time, passes into the air from the air chamber, the material blown into the discharge elbow, and then introduced another stock pressure by the cyclone, which will let the material be blown, accelerated, and rotating, floating into the conveying pipe to reach the nozzle and then add a small amount of added water (when it's the the tide spray) or liquid accelerator (when it's the wet spray ) and last sprayed it out.
PZ-9 type concrete spraying machine mainly consists of driving device, the rotor assembly, air duct systems, injection systems, electrical control box and other components.
