Concrete sprayer/ Shotcrete machine

Introduction of concrete spraying machine :

Shotcrete process is to use compressed air to convey the predampened mix through delivery hose to the nozzle 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, economy cost, flexibility and high construction efficiency,shotcrete technology has widely been applying in construction, railway and super highway engineering, underground engineering, tunneling, mining operations, hydropower projects and slope stabilization, etc.and showing prosperous future.

Features of concrete spraying machine :

1Non adhesion going through rotor with new material chamber, completely eliminate bonding and blocking during operation so as to reduce clearance and maintenance period.

2Thin flow conveying method with vortex flow, so the spraying flow is even, continuous and steady, to improve the shotcrete quality.

3Fourpoint 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.

Application of concrete spraying machine :

Shotcreting for tunnels, hydropower engineering, mines, underground engineering, civil engineering and slope stabilization, etc.

Artificial soil seeding for no soil surface, such as rock, sand, and for no fertility soil surface.

Refractory spraying and repair for industrial kilns or kilns’ inner liner.
