                                NM wet concrete pump

NM-600 type wet concrete spraying machine patented products developed independently by our company can be widely used in the tunnel and slope supporting engineering, mine roadway reinforcement, reinforcement works construction, water tunnel project, TBM pea gravel delivery, copper smelting refractory concrete spraying jet construction and other fields.

1.General Description
Step method in tunnel construction and the small section tunnel construction, the use of hand-held spray NM series of wet spraying machine, compared with the use of vehicle-mounted wet spraying operations trolley (spray robot), with easy construction work, quick, adaptable, etc. Features (saving time: eliminating the need for disassembly trolley in the construction process; flexible: small footprint machine, a small anchor and interfere with other processes; simple: Workers hand to spray, simple process operation).In the full-face tunnel construction, it is possible to use 2-4 sets NM series wet spraying machine operations at same time to achieve the operation effect of the generous amount of concrete spray.

2.Introduction
NM-600-type wet concrete spraying machine works principle
Mix was added from the feed discharge opening and flows into the rotor chamber under gravity, mixing materials together with the rotor chamber continuously rotate around axis, which orifice communicates with the compressed air inlet holes formed primary blow forehearth. The first unit of compressed air quickly clear the rotor chamber, mixing materials are rushed into the discharge chamber,at the same time adding compressed air in the bottom of the discharge chamber of secondary air inlet elbow make the concrete material with a liquid accelerator in mixing chamber at the nozzle ,then Via high-speed jet nozzle to the working face, because of the continuous rotation of the rotor, 9  uniform cloth material holes on the rotor continuously interlinke with the discharge opening and air intakes , Continuous cycle like this,to complete continuous injection.
