One of the dominant models of wet concrete jet piston pump concrete jet, the material is uniform, compact, low operating dust concentration, rebound, spray the advantages of the concrete strength, widely used ecological slope protection, mining bolting and shotcrete support, tunneling, construction

One of wet concrete jet aircraft at present leading types is the ram pump type concrete jet aircraft, it has the material evenly, the structure compact, the work dust density low, the snapping back few, the spraying concrete intensity higher merit, widely applies in the ecology slope protection, the

Wet concrete Jet is currently one of the leading models are piston pump concrete injection machine, out of uniform, compact structure, less dust concentration is low, the rebound in job benefits, and high strength of sprayed concrete, widely used in ecological slope protection, bolting and shotcreti
