Abstract
A positionable gas nozzle assembly for injecting and directing pressurized air or other gas having an inert nature into a pellet slurry so as to increase the velocity of the slurry from a pelletizer to and through a dryer. The variably positionable nozzle can be inserted, retracted and/or intermediately positioned to facilitate start-up of the pelletization process, reduce or eliminate pellet hang-up points, maximize and optimize the velocity of the pellet slurry throughput, and to adjust the aspiration level of the pellet slurry such that the internal heat of the pellets is retained for improved degrees of crystallization and/or drying.
