DRYER FEED NOZZLE ASSEMBLY

摘要

A feed assembly for fluid energy type mills wherein dispersions of granular material or solutions are fed through a nozzle and are entrained in tangentially directed jets of gaseous fluid which create a vortex in front of the jet nozzle and atomize or aspirate the wet particles. A vacuum which is formed between the tip of the feed nozzle and the vortex is broken and which thereby creates a suction to pull particles back against the nozzle tip, causing abrasion, is broken by the insertion of low pressure gaseous fluid between the vortex and the nozzle tip.
