    摘要: An apparatus for the gunning of a material is provided having a nozzle with an inner passage having an inlet end into which a wetted material is to be introduced and an outlet end from which the material is to be sprayed. An outer passage is disposed around the inner passage and in fluid communication therewith and has an inlet end for introducing a gas to be passed through the outer passage and impinged on the wetted material passing through the inner passage. Also provided is an apparatus for the gunning of a material having a material delivery hose for providing a material. A water inlet in fluid communication with the material delivery hose provides water to wet the material and a nozzle outputs the wetted material. A mixing chamber is disposed intermediate and in fluid communication with the material delivery hose and the nozzle and has at least one inlet for introducing a mixing gas.

    摘要: An improved apparatus for the gunning of a material is provided having a nozzle with an inner passage defined by an inner tubular member having an inlet end into which a wetted material is to be introduced and an outlet end from which the material is to be sprayed. An outer tubular member is disposed around the inner tubular member defining an outer passage between the inner and outer tubular members. A compressed gas is passed through the outer passage and impinged on the wetted material exiting the inner passage to better control the spray pattern of the wetted material. The inner tubular member extends out beyond the outlet end of the outer tubular member and the inner surface of the outer tubular member and the outer surface of the inner tubular member near the outlet end are chamfered to provide an optimal attitude for the impinging air.
