MULTISTAGE VIBRATION MILL Russian patent published in 2017 - IPC B02C19/16 

FIELD: machine building.

SUBSTANCE: invention relates to various materials of mineral and organic origin fine grinding equipment. Multistage vibration mill comprises drive shaft 3 with diametrically opposite eccentrics and two units of grinding tube chambers 4 and 5. In each unit chambers 4 and 5 are connected to each other and with drive shaft 3 by means of drive in form of multi-beam regular sprocket 7 with supports for chambers 4 and 5 at ends of beams, installed on drive shaft corresponding eccentric. One unit grinding chambers are arranged in clearances between other unit grinding chambers due to one unit sprocket angular displacement relative to other unit sprocket, wherein in each unit grinding chambers are sequentially connected to each other by identical junctions with of loading branch pipe arrangement at first chamber inlet in sequential loop and discharge branch pipe arrangement at last chamber outlet. Common for both units number of junctions, arranged on side of grinding chambers one similar ends, corresponds to number of junctions, arranged on side of other similar ends.

EFFECT: mill enables higher efficiency of grinding and increasing thinness in one material passage.
