Introduction of PZ Series Concrete Spraying Machine
PZ series shotcrete gunite machines are widely used in underground engineering, roadway, mining, tunnels, culverts, etc. PZ series shotcrete gunite machine uses compressed air to convey the concrete along the pipeline continuously and then sprayed the material to the construction machinery.
PZ series shotcrete gunite machine mainly consists of driving device, the rotor assembly, air duct systems, injection systems, electrical control box and other components.

Features of PZ Series Concrete Spraying Machine
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;
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.
