Wet Mix Concrete Spraying Shotcrete Machine HS700 

HS-700/600 is a new generation of wet-mix concrete spraying machine developed by Weibang company and Germany ISAI company. The wet shotcrete machine on the principle of rotor-piston cam feeding mechanism is at the world leading level.
Main Features:
1, Forced feeding by the piston completely avoiding material sticking in rotor material chambers, high adaptation to the concrete(regardless of highly viscous concrete or fiber concrete).
2, Synchronously radial feeding of three material chambers leads to rarefied flow, flowing continuity, no plugging, small recoil force of spray nozzle, low rebound, smooth spraying surface.
3, Liquid accelerator system allows accurate dosing and uniform mixing.
