How to choose a suitable sprayer?

Everyone may know that the sprayer is generally divided into a dry sprayer and a wet sprayer. However, how to choose a suitable sprayer? The simplest method is to choose according to the degree of dryness and wetness of the slurry added to the sprayer. Henan Hao Li spraying machine manufacturers specifically for you to introduce how to properly choose the right spraying machine.
The injection slurry added by the sprayer is dry, such as concrete, cement, etc., and no water is added or a small amount of water is added. Added is a well-mixed mixture, such as concrete, cement, and water, and then sprayed. Because dry concrete or cement is added, the spray head needs to be filled with water in order to ensure the spraying effect and not generate too much dust. The wet spraying machine uses water to fully mix concrete or cement, and then sprays it. No water is added at the nozzle, and no dust is produced. This ensures the working environment.
The spraying machine can reach a conveying distance of up to 200 meters or more, and the slurry sprayed by the wet spraying machine is a slurry that has been stirred and has a viscosity, so the vertical conveying distance can only reach 20-30 meters, and the horizontal conveying distance is 30- 50 meters. The sprayer can achieve a spray pressure of 7 cubic centimeters and a wet spray of 13 cubic meters will work.
The operator and safety are different. Shotcreting machines need to occupy a large number of operators, due to a large amount of dust generated, not only affect the environment, but also the safety of production and physical harm to workers, and is not conducive to underground construction operations.
Because the slurry has been previously mixed, the wet spraying machine is not required to occupy a large amount of manpower and does not generate dust. This has little impact on the workers and the environment and is applicable to various working environments.
The resilience rate of the spraying machine will reach 15-50%, and it will also cause poor cohesion. Especially in downhole construction, it will be deformed and deformed by the earth's crust, causing splitting and destruction. The wet rate of the wet spraying machine is only up to 10%, and since the slurry is previously mixed well with the water-cement ratio, the cohesive property is high, and it is not easy to deform with the change of the crust, which plays an important role in the safety production. .
