Apparatus for applying granular refractory material to surfaces

摘要

Our improved nozzle mounting comprises a support member for the nozzle secured to the projecting end of the innermost or granular material carrying conduit. The nozzle is mounted on a horizontally disposed pivot, carried by said support member. Granular material is conveyed from the lower end of the granular conveying pipe to the nozzle through a flexible member and water is supplied to the mixing nozzle by means of a flexible water pipe or hose. Our improved mixing nozzle mounting is simpler in construction than the one shown in our aforesaid patent and hence is cheaper to construct and maintain inasmuch as we have eliminated various rotary seals, gears and the like.
