METHOD AND DEVICE FOR DISTRIBUTION OF SOLID LOOSE MATERIALS Russian patent published in 2013 - IPC G01F13/00 

FIELD: machine building.

SUBSTANCE: device for controlled distribution of solid loose materials includes material container (3) with a set of outlet holes (33), a set of distributing elements (4), a set of vibration devices (5, 50) and electronic control devices for bringing into movement of each vibration element (5, 50) irrespective of each other. At that, each of the set of distributing elements is located at some distance under outlet hole (33) so that the material leaving each hole (3) can be accumulated on the above element. Each of the set of vibration devices (5, 50) is connected to the corresponding distributing element (4) for transfer of vibration to it so that accumulated material slides along distributing element (4) till it flows over edge (41).

EFFECT: improving distribution efficiency of material on the treated surface; improving printing quality, reliability and simplifying the design.
