Wet spraying machine

Concept of wet spraying machine

Wet spraying machine is currently an anchor spraying support equipment with good comprehensive performance in reducing dust, minimizing rebound, and saving materials both domestically and internationally.

Wet shotcrete machine is a widely used construction equipment in engineering construction. It uses compressed air or other power to mix and mix materials in proportion through pipelines and sprays them at high speed onto the sprayed surface to solidify and harden, forming a concrete support layer. The shotcrete technology is simple, the construction cost is low, the adaptability is wide, the operation dust is small, the spraying rebound is low, the working environment is protected, raw materials are saved, and the quality of the sprayed layer is improved. It has played an important role in various construction fields.

Application of wet spraying machine

Wet spraying machines are generally used for underground operations in mining areas, also known as mining wet spraying machines. In fact, wet sprayers have a wide range of applications. In addition to being used in mining areas, they can also be used for daily care such as irrigation, fertilization, pesticide spraying, and soil improvement work. In addition, wet spraying machines are also suitable for greening and spraying in places where plant growth is difficult, such as rocks, hard soil, sandy soil, barren land, acidic soil, arid areas, and coastal dams. They are used for highway slope greening, high-speed railway side greening, mine greening, ecological restoration, desert control and other projects.

Structural characteristics of wet spraying machine

The special vibrating hopper can facilitate the smooth entry of wet concrete mixture into the rotor material chamber; The new metering pump can accurately and uniformly add liquid accelerators; The patented discharge elbow ensures uniform, continuous, stable, and low pulse flow of the material, and eliminates the blockage caused by wet concrete bonding, reducing the working air pressure of the system.

Main advantages of wet spraying machine

1.Greatly reducing the concentration of dust near the machine and outside the nozzle, eliminating the harm to workers' health.

2.High productivity.

3.Low rebound degree, when dry spraying, the rebound degree of concrete can reach15％-50%By using wet spraying technology, the rebound rate can be reduced to10%One moment.

4.During wet spraying, due to the easy control of water cement ratio and high degree of concrete hydration, the quality of sprayed concrete can be greatly improved, and the homogeneity of concrete can be enhanced. However, during dry spraying, the water cement ratio of concrete is adjusted by the spraying operator based on experience and visual observation, and the quality of concrete largely depends on whether the operator operates correctly.
