Series PZ Wet-mix Shotcrete Machine

Description

The operating principle of Series PZ wet-mix shotcrete machine is to use compressed air to convey the pre-dampened mix through delivery hose to project the material onto the sprayed surface under high velocity, and then to form concrete support layer after the projected material coagulates and hardens.
With simple technology, special effect, cost-effective, flexibility and high construction efficiency, Concrete spraying machine has widely been applying in construction, railway and super highway engineering, underground engineering, tunneling, mining operations, hydropower projects and slope stabilization, etc.

Advantages of Series PZ Wet-mix Shotcrete Machine

1. Non-adhesion going-through rotor with new material chamber, completely eliminate bonding and blocking during operation so as to reduce clearance and maintenance period.
2. Thin flow conveying method with vortex flow makes spraying flow even, continuous and steady and improves the shotcrete quality.
3. Four-point clamping device makes it easy to adjust the press between sealing plate and rotor disk.
