Dry concrete spraying machine for tunnel shotcrete can also be used for small tasks such as joint filling, pooling, refractory coating, and large slope integration work.
Depending on the casting process, the concrete spraying machine for tunnel shotcrete is divided into a dry-type mixer and a wet-type mixer. With a dry spray gun, the material drains up to 5% of the water from the machine and then sends the material through the air stream to the nozzle assembly, where it adds the required water (usually 5-10%). In a wet concrete spraying machine for tunnel shotcrete, the gun material is pre-moistened with water in a blender and pumped through a hose via an eccentric screw or piston pump. At the end of the production line, the material is dispersed with compressed air and additional liquid binding / curing agents can be added as needed (shot cleating). Usually, you need to add an accelerator.

Dry concrete spraying machine for tunnel shotcrete
Dry concrete spraying machine for tunnel shotcrete is commonly used for outdoor engineering such as bridge maintenance, pooling, and slope protection. Wet concrete spraying machine for tunnel shotcrete are widely used in indoor engineerings such as mining, tunnels, subways, and other projects. Wet concrete spraying machine for tunnel shotcrete are mainly used in more critical projects with less dust, lower repulsion rate, and higher spray intensity than dry mixers. Regardless of the jet concrete machine, you need an air compressor to supply compressed air.
