VIBRATING FEEDER Russian patent published in 2005 - IPC

FIELD: mining industry.

SUBSTANCE: invention relates to vibrating facilities and it can be used for letting out ore or other materials and their separation. Proposed vibrating feeder has resilient supports, working member consisting of charging and discharge parts and vibrating drive consisting of two shafts with unbalance weight and motors, one per each unbalance weight. Place of arrangement of vibrating drive is determined basing on the fact that line of connection of axles of unbalance weights is located in area limited by two straight lines square to direction of vibration, one of which passed through center of mass, and the other is located at a distance from center of mass of 1/10L to side of charging part of working member. Axle of unbalance weights are located at different sides from line of direction of vibration passing through center of mass at distance equal to not less than 1/8 where L is distance between resilient supports in horizontal direction.

EFFECT: improved stability of operation of vibrating feeder at unstable supply and impact loads on working member at discharging.
