Professional shotcrete machine manufacturer
The introduction of Gengli shotcrete machine
Gengli is a professional manufacturer of shotcrete machine products. The products include dry mix shotcrete machine, wet mix shotcrete machine, Truck-mounted Shotcrete Machine and Truck-mounted Robot Shotcrete Machine.
Shotcrete machine is a kind of equipment that is widely used in mines, tunnels, culverts, subways, water conservancy projects, and underground works shotcrete construction operations. Shotcrete machine can be used as well for small jobs, such as joint filling, swimming pool, refractory application and extensive slope consolidation work, etc.
Gengli has two types of shotcrete machines：dry shotcrete machine and wet shotcrete machine. What is the difference between dry shotcrete machine and wet shotcrete machine?
1.The degree of dryness and wetness of the slurry is different. The spray slurry added by the dry shotcrete machine is dry, such as concrete, cement, etc., without adding water or adding a small amount of water. The wet spraying machine adds a uniformly mixed mixture, such as concrete, cement and water, and then sprays it out.
2.The shotcrete mode is different. Because dry concrete or cement is added to the dry-type shotcrete machine, when spraying, the nozzle needs to add water to ensure the spraying effect and not generate too much dust. The wet shotcrete machine uses water to fully mix concrete or cement, and then sprays it. There is no need to add water at the nozzle, and it does not generate dust, which ensures the working environment.
3.The conveying distance and wind pressure are different. The conveying distance of dry-type shotcrete machine can reach more than 200 meters, while the slurry sprayed by wet-type shotcrete machine is already agitated and viscous slurry, so the vertical conveying distance can only reach 20-30 meters, and the horizontal conveying distance is 30 -50 meters. Dry shotcrete machine can be sprayed when the air pressure reaches 7 cubic meters, and wet shotcrete machine needs 13 cubic meters to work.
4.Operators and safety are different. Dry shotcreting machines require a large number of operators. Due to the large amount of dust generated, it not only affects the environment, but also causes great harm to safe production and workers, and is not conducive to underground construction operations. Since the slurry has been mixed before, the wet spraying machine does not require a lot of manpower and does not generate dust, which has little impact on workers and the environment, and is suitable for various working environments.
5.The difference in resilience and cohesion. The rebound rate of dry shotcreting machine reaches 15-50%, and it will also cause poor cohesion, especially in underground construction, which will be deformed by changes in the earth's crust, causing split and damage. The rebound rate of the wet shotcrete machine only reaches 10%, and because the slurry is previously stirred according to the water-cement ratio, it has high cohesion and is not easy to deform with the change of the earth's crust, which plays an important role in safe production.
Gengli has an extensive line of shotcrete machines that can perfectly match your expectations. If you are considering a shotcrete machine that will provide longstanding value, allow Gengli to select the right model for your requirements.
