APPARATUS TO PRODUCE HIGHLY DISPERSIVE DRY AEROSOLS Russian patent published in 1994 - IPC

FIELD: chemical industry. SUBSTANCE: dosing apparatus is made in the form of two millstones. First millstone is capable to rotate and has form of truncated cone. Second millstone is stationary and has cone hole, corresponding to form of first millstone. Cyclone mill is made as flat horizontal milling chamber with not less than nine working nozzles and coaxially mounted in it hollow cone with tangential holes in generatrix surface and holes are oriented in direction, that is opposite to milling chamber jet stream rotation. Joint to separate large-scaled particles from cyclone mill out-going aerosol stream is made in the form of two connected in series cyclones. EFFECT: simplification of production and increase of produced aerosols quality. 2 dwg
