Devided into wet mix shotcrete machine and dry mix shotcrete machine according to the different produce process. Spraying concrete shotcrete machine is mainly used for spraying concrete in mining, tunnel, culvert, subway, hydopwer engineering, underground excavation engineering.
For wet mix shotcrete machine, the spraying soil, cement, stone need first be mixed with water in the mixer, and then pure the mixing concrete into the hopper of shotcrete machine. While dry mix shotcrete machine, it add dry soil, cement, stone in the hopper of shotcrete machine, finally adding water in the nozzle.
Compared to dry mix shotcrete machine, wet mix shotcrete machine have more advantage, such as low rebound, low dust, having much higher strength.
For customers, low rebound can greatly save concrete materials, further more, it can give the customers more economic benefits.
Whichever kind shotcrete machine working all need air compressor to provide compressed air. Shotcrete machine is also rotor type shotcrete machine, thin flow shotcrete machine. It feed materials by rotor rotating, and then compressed air to deliver a certain proportion of the mixing material through the conveying hose and spray it at high speed to the surface to be hardened by the spray surface.
We could provide air motor, electric motor and diesel engine three kind drive type shotcrete machine for customers. For some remote working site, it is not easy to get electric supply for customers, so they are willing to choose air motor and diesel engine shotcrete machine. Here the voltage is 380V, 50HZ, 3phase, for some different voltage customers, we could also customize required voltage motor for customers. Whichever shotcrete machine, all need suitable air compressor to provided compressed air. While for air motor drive, same model shotcrete machine will need much bigger air compressor. Because it doesn’t only need provide compressed air to deliver a certain proportion of the mixing material through the conveying hose, but also it need extra compressed air to drive air motor.
