Sprays 19 at or just beneath the duct inlet 4 direct water downwardly so as to wet the particulate material. Preferably the apparatus is used for wetting friable particulate material, in which case the sprays direct water across the path of the downflowing particulate material so as to disintegrate it into individual particles and to wet these. Downflow of air is minimized by providing a cowl 9 over the top of the duct and by feeding the particulate material, generally by a screw feed 13, into a passage that leads from an inlet 15 that is exposed to the atmosphere to an outlet that discharges direct into the duct inlet 4. | InventorsAssigneeApplicationNo. 446845 filed on 10/12/1995US Classes:366/137.1, JET OR SPRAY IMPINGING FREE-FALLING STREAM239/113, System fluid diverted239/424.5, Plural passages discharge one fluid to other239/425.5, Ambient air aspirated through inner flow path366/138, WITH FLUSHING OF MIXING CHAMBER366/173.2, Plural injectors for material from same source366/178.2, Feed means has plural identical outlets366/347COVER OR SHIELD FOR MIXING CHAMBERField of Search366/9, Gravity type366/137.1, JET OR SPRAY IMPINGING FREE-FALLING STREAM366/138, WITH FLUSHING OF MIXING CHAMBER366/167.1, Liquid injector within mixing chamber366/173.1, Plural injectors366/173.2, Plural injectors for material from same source366/178.1, Concentric366/178.2, Feed means has plural identical outlets366/178.3, Inner feeder passes through wall of outer feeder and extends along common axis at the wall366/181.6, Feed means has plural identical outlets366/341, STATIONARY MIXING CHAMBER366/347, COVER OR SHIELD FOR MIXING CHAMBER239/113, System fluid diverted239/420, Including movable means for varying point of convergence239/422, Combining of three or more separate fluid streams239/423, Concurrent or concentric flow means239/424, Flow means of one fluid surrounds the other at outlet239/424.5, Plural passages discharge one fluid to other239/425.5, Ambient air aspirated through inner flow path239/428.5, Liquid flow induces atmospheric air (e.g., faucet aerator)239/430Three or more inlets to one stream from otherExaminersPrimary: Cooley, Charles E.Attorney, Agent or FirmUS Patent References2224355, 2746728, 3029069, 3164443, 3542342, 3741533, 4086663, Mixing apparatus and methodIssued on: 04/25/1978 Inventor: Croft4488407, Process for making slush Issued on: 12/18/1984 Inventor: Delano4531673, Spray jet polymer powder wetter Issued on: 07/30/1985 Inventor: Holland , et al.4643582Wetting chamber Issued on: 02/17/1987 Inventor: Ricciardi Foreign Patent References
