Product Description

Anti-explosion Wet Spraying Machine
Other Names:Wet spraying machine; Explosion-proof shotcrete machine
Product Introduction
Anti-explosion wet spraying machine can significantly improve underground construction environment, reduce dust to protect workers' health, improve supporting strength, effectively control the quality of concrete injection, significantly reduce spring rate of the concrete. More effectively reduce costs, improve economic efficiency and productivity of coal enterprises.
Anti-explosion wet spraying machine, when wet spray, is easy to control and because of the water-cement ratio, high degree of curing concrete, it can greatly improve the quality of shotcrete to improve the homogeneity of the concrete.
Anti-explosion wet spraying machine is mainly used in mining roadway, railway and highway tunnels, underground construction, high-rise building foundation and road slope and high marsh coal mine tunnel shotcrete construction operations.
Structure feature
1. simple structure, easy to operate.
2. high working efficiency, the use of hydraulic pumping mode, the system reliability, throughput and stability.
3. high pressure pump, transmission distance, difficult to adapt to the construction environment.
4. the injection quantity continuously adjustable, the main use of variable displacement piston pump, jet speed can be adjusted freely.
5. sprayed layer of concrete high-performance, dense, homogeneous, high strength, and high performance.
6. the use of automatic lubrication system, grease filling volume, filling time automatic control, effectively extending the service life of the various components.
7. the key component quality is stable and reliable.
8. reducing machine next and dust concentration outside the nozzle, eliminating the need for workers' health.
9. a multi-purpose machine, you can use it both as a wet spraying machine and a concrete pump.
