METHOD OF VIBRATION TRANSPORTATION OF DISPERSED MATERIALS AND VIBRATION FEEDER DESIGN Russian patent published in 2002 - IPC

FIELD: mining construction and metallurgical industries. SUBSTANCE: according to proposed method of vibration transportation of dispersed materials, harmonic vibrations of equal amplitude in all points are imparted to transportation member from drive of unbalance vibration exciter. Initially flow of dispersed material is directed to transportation member according to free fall trajectory. Under vibration boiling conditions material is distributed over entire length of transportation member across direction of falling flow with subsequent uniform unloading of dispersed material from transportation member. Vector of maximum harmonic vibrations is directed square to falling flow trajectory. Vibration feeder for transportation of dispersed materials has transportation member made in form of trough installed on fixed base by means of flexible members, and vibrodrive. Transportation member is installed direction of material falling flow being made with loading and unloading walls. Angle of inclination of unloading wall is greater than angle of inclination of loading wall, being equal to β≥α+15^°,, and angle of inclination of loading wall being equal to 90^° ≤ α ≤ 110^°. Length of transportation member exceeds width of falling flow. EFFECT: provision of transportation of dispersed lump material of different size by vibration with provision of uniform distribution and uniform charging of equipment operating members. 3 cl, 5 dwg
