Introduction of Wet Building Gunite Machine
Easy Operation and Maintenance
Wet Building Gunite Machine also named wet shotcret machine, wet concrete spraying machine is a concstruction equipment used for wet spraying concrete, compared with the dry shotcrete machine, tidal guniting machine, Wet Building Gunite Machine has a small working dust,
Less injection rebound, protect the working environment, save raw materials, improve spray quality and other significant advantages, but also easy to operate and maintain.
Uniform and Stable Guniting
Wet Building Gunite Machine adopting low-pressure low-speed vortex airflow delivery and short-distance shotcreteing work to overcome the problems of plugging, pulse, segregation, etc.
Features of Wet Building Gunite Machine

Reasonable Sealing
Structure
Reasonable sealing structure, reducing the degree of dust pollution, less dust
Low Springback, Material Saving
Wet Building Gunite Machine
Material Saving
Wet Building Gunite Machine is used for spraying wet concrete with advantages of small working dust, less ejection rebound, protecting working environment, saving raw materials, improving spray quality, operation and maintenance convenience.
Concrete has been mixed well before injection, to ensure the mix ratio, thus ensuring the quality of concrete.
Structure and Working Principle
Structure
Wet Building Gunite Machine is mainly consists of driven motor, reducer, turn the font assembly, sealing plate, hopper seat, vibration hopper,
pressing mechanism and quick-setting agent delivery system, air duct system, electric control device and other components.
Working Principle
01
Concrete is mixed according to the ratio by the concrete mixer and added to the vibration hopper, to the rotor body cavity through the screen, the rotor body will rotate the material to the panel discharge port, compressed air after " wind device " is divided into three routes: one to the quick-setting admixture mixer, one to the cyclone (downwind), and then one route to the hopper seat (windward), the wind through the hopper seat, rotor body cavity, through the panel outlet. Therefore, when rotor body cavity with material reaches the discharge opening, the compressed air blows the mixture through the swirler and the sand blast tube to the spray head. The woenwind air passes through the swirler to form a cyclone, so when the material flow through the cyclone, the material has been accelerated rotation, which is not easy to produce sticky blocking tube.

02
The addition of liquid quick-setting admixture is accomplished by a conveyor system consisting of a quick-setting admixture pump, accumulator, manifold, flow meter and other components. Manifolds include relief valves, check valves, mixing chambers. The liquid quick-setting agent is pumped out of the tank by the quick-setting admixture pump, then flows through the overflow valve, the regulating valve and the flow meter to the mixing chamber to blow quick-setting agent to the nozzle seat and spout out with mixed material.
Application of Wet Building Gunite Machine
Wet Building Gunite Machine is widely used for shotcrete construction work in mines, tunnels, culverts, subway, hydropower projects, underground works and coal mine, tunnel.
