Abstract: A liquid slurry spraying system for spraying highly viscous slurries, including those with solids content, while maintaining the slurry in agitated condition for optimum discharge. The spraying system includes a nozzle body with a liquid flow passage having a liquid slurry inlet adjacent an upstream end and a spray tip at a downstream end, a valve needle supported in the liquid flow passage for reciprocating movement between spray tip closing and opening positions, and a bladed rotor having a plurality of vanes rotatably supported on the valve needle for rotation as an incident to the direction of liquid slurry from said liquid inlet when the valve needle is in an open position for agitating the liquid slurry for direction to the spray tip.
