DEVICE FOR SUPPLYING POWDER Russian patent published in 2004 - IPC

FIELD: medical engineering. SUBSTANCE: method involves applying electrostatic frictional charging. Disagglomeration takes place on two brushes touching each other in rotating carrying powder in preferential embodiment. Brush bristles come into friction engagement with each other and agglomerates are split. Brush rotation speed is selected to reach maximum achievable efficiency for each kind of powder substances. Brush design is selected before carrying out disagglomeration and electrostatic frictional charging. EFFECT: wide range of functional applications. 14 cl, 4 dwg
