A concrete gunite machine is a machine that sprays concrete along a pipeline onto a construction surface through compressed air. There are two main types of concrete shotcrete machine: dry and wet gunite. This equipment is widely used in slope support, hydropower engineering, underground engineering and concrete spraying of mine roadway. Shotcrete spraying machine can play the role of support, filling, insulation and transformation. There are certain differences between the two construction techniques of dare spraying and wet spraying. The following are the introductions for you.
Dry shotcrete machine
The dry spray method is a method of mixing cement, sand, and stones with a particle size of less than 25 mm in a certain proportion, and then loading the materials into the machine and spraying them on the construction surface. The dry shotcrete shotcrete machine first feeds the mixed material into the hopper of the jet machine through the vibrating screen. Then it is injected into the material cavity of the rotor by pulling the material. When the material follows the rotor to the outlet, the compressed air blows the material from the air chamber to the discharge elbow. At the same time, the cyclone introduces another compressed air. Multiple winds accelerated the concrete and sprayed it out.
Wet concrete spraying machine
The wet shotcrete machine has one more acceleration conveying system than the dry shotcrete machine. Compared with the dry shotcrete machine, the wet shotcrete machine is more widely used. Because the wet shotcrete machine can not only spray dry material but also spray wet material. Wet shotcrete machines are generally used for underground operations in mining areas, and can also be used for soil improvement work, green spraying, mine regreening, ecological restoration and other projects.
The working process of the wet shotcrete machine is to deliver the mixed concrete to the nozzle, and then pass the compressed air into the delivery pump port. The material and air are fully integrated in the pipeline. Since the accelerator is added at the nozzle, the material can be quickly solidified when sprayed, reducing the rebound rate.
What are the advantages of shotcrete machine?
Shotcrete machine is a new type of energy-saving and environmentally friendly construction machinery and equipment that has been continuously developed and improved. It contains two types of shotcrete equipment, suitable for spraying dry and wet materials. When spraying, the concrete does not stick to the material cavity, the discharge is smooth, the efficiency is high, and the workload of cleaning and maintenance is reduced. It is not only suitable for support and mine use, but also suitable for green spraying, ecological restoration and other functions. The shotcrete machine produced by Yugong has the characteristics of wear resistance and durability, long service life and reduced maintenance.
In addition, Yugong Construction Machinery Equipment also provides other construction machinery and equipment. For example, excavator shear, mini concrete pump, sand blasting machine, shot blasting machine, concrete wall saw, Punching And Shearing Machine,ect.
