Abstract
Rotor gun means for the air placement of granular and cementitious material. A mixing chamber for granular and cementitious materials, has a rotor gun mounted therein. The rotor gun comprises a motor driven wheel having a plurality of holes or apertures equally spaced about said rotor wheel. The apertures pick up the material and pass in front of a source of high pressure air stream which blows the material from the apertures.
Claims2
Rotor gun means for the air placement of granular and cementitious material, comprising,
- a mixing chamber for granular and cementitious materials,
- a driven shaft mounted parallel to the bottom of said chamber,
- a rotor freely floating on said shaft in predetermined space relation in said mixing chamber,
- said rotor comprising a motor driven wheel in the central portion of said chamber, said wheel having a plurality of apertures equally spaced about said rotor wheel, said apertures being adapted to pick up said material,
- and a source of high pressure air stream connected to blow said material from said apertures as said apertures pass said high pressure air stream, into an outlet nozzle without any bends or turns in the path of the air stream,
- a pair of resilient sealing pads, said rotor wheel passing between the pair of sealing pads, and means to adjustably mount at least one of said sealing pads in place, comprising a pair of steel plates one each on the outer sides of said pads and adjustable screw operated means for adjusting the pressure of one of said plates against one of said pads.
