Abstract
The present invention provides a slurry spraying or installation system (10) including a gun means (12), a spray nozzle (17) and a conduit (16) connecting said gun means (12) to said spray nozzle (17), said gun means (12) including a pump means to move dry particulate towards said nozzle along said conduit (16), wherein between said gun means (12) and said nozzle (17) is a mixing device (20) which receives said dry particulate and mixes same with liquid under a greater pressure than the pressure that said dry particulate is under, so as to form a liquid and dry particulate mixture; said mixture being fed to said nozzle (17) for dispensing to a target.
Claims40
A slurry spraying or installation system including a gun means, a spray nozzle and a conduit connecting said gun means to said spray nozzle, said gun means including a pump means to move dry particulate towards said nozzle along said conduit, wherein between said gun means and said nozzle is a mixing device which receives said dry particulate and mixes same with liquid under a greater pressure than the pressure that said dry particulate is under, so as to form a liquid and dry particulate mixture;
- said mixture being fed to said nozzle for dispensing to a target.
A mixing device to preform a settable slurry, said device including an inlet having a larger internal cross sectional area than a hose connected to said device to deliver to said device a dry particulate under pressure to be preformed into said slurry, a diverging passage extending from said inlet and a transition passage located downstream of said diverging passage, said transition passage having a substantially constant cross section, and a liquid inlet being located in one said diverging passage or said transition passage.
