HSP type concrete wet spraying machine is a new high efficient concrete machinery, mainly used for wet concrete, enabling mixture mixing evenly, accurate control of water will help cement hydration, so little dust , rebound small, concrete homogeneity and high strength. This machine have reasonable structure, stable performance, easy operation and maintenance, long service life, widely used in iron (public) road tunnel, subway, hydro power engineering, underground engineering and mine shaft shotcrete construction operations. High Quality Wet and Dry Shotcrete machine is concrete shotcrete machine. This kind shotcrete machine uses the compressed air to convey or high-speed jet concrete mix with a certain proportion to the surface through the pipelines. The concrete mix on the surface set and harden to form concrete support layer. In recent years, shotcrete technology with a simple process, an unique effect, the economic cost and fast construction speed, is widely used in construction, rail and road tunnel construction, mine development, slope reinforcement and other fields. Feature Greatly reduce the dust density next machine and outside of nozzle when the working of HSP type concrete wet spraying machine , eliminate health hazards to workers;high production rate; resilience is low;
