Shotcrete machine, is a new type and high efficiency spraying machinery, mainly suitable for the section concrete spraying operation of section. It has reasonable structure, humanized design, reliable performance, convenient operation and maintenance, and long service life. Dust-free, low noise and low resilient rate when working. The working principle of spraying machineï¼? The equipment uses a rotor pump to deliver the concrete to the nozzle through the pipeline, and the concrete is sprayed to the wall of the sprayed tunnel by the compressed air along with the accelerator agent. Application: 1.Widely used in engineering construction, mines, tunnels, culverts, subway, hydropower projects, underground projects and coal bog mine roadway shotcrete construction operations. 2.Spray molding or repair of refractory materials for all kinds of industrial furnaces and kilns and lining. 3.Soil transportation and spraying during all kinds of slope protection and greening construction. 4.This machine can be used for wet spraying, dry spraying and all kinds of fiber spraying.
