How does it work?

The shotcrete machine for sale is a mechanical equipment that combines mechanics, electricity and hydraulics. The hydraulic wet spraying machine uses the thrust generated by the hydraulic pump to make the two cylinders move back and forth alternately. The dense flow material is sent from the conveying pipe to the mixed flow pipe. The compressed air forms a thin flow and is sent to the nozzle through the pipe. A certain proportion of quick-setting agent is added to the nozzle and sprayed directly onto the spray surface.
