Shotcrete machine Application:

Concrete shotcrete machine are mainly used for railway and highway, subterranean basement walls, Seismic reinforcing/ retrofitting of buildings, channels, shear Walls, retaining Walls, bridge retrofits, architectural concrete, mining, tunnel, culvert, subway, hydropower engineering(such as tunnels,dams and pools) and underground excavation engineering etc.

It has many obvious advantages such as simple structures, easy operation and convenient after sales service and very long serviceable life etc.


1. High quality, reliable performance.

2. Good seal performance, little dust.

3. Reasonable design, convenient to move.

4. Convenient operation and longevity of service.

5. Non-adhesion going-through rotor with new material chamber, completely eliminate bonding and blocking during operation so as to reduce clearance and maintenance period.

6. Thin flow conveying method with vortex flow, so the spraying flow is even, continuous and steady, to improve the shotcrete quality.

7. Four-point clamping device make it easy to adjust the press between sealing plate and rotor disk so as to no air and dusk leak and prolong consumption parts life.

8. Widely used in mining, tunnel, culvert, revetment etc.
