Singulating vibration feeder

A vibrating conveyor/singulator based on the dynamically balanced principle with a counterweight, parts of which extend along a conveying trough, creating a relative movement with a particular frequency, comprising a conveying trough defined by three parts, a lower part forming part of a shallow trough connected to a vibration driver that cause its longitudinal vibration, and a pair of upwards-and-outwards extending parts disposed along opposite sides of the lower part and connected to means that enable a longitudinal reciprocating movement at said particular frequency and at a smaller amplitude than the longitudinal vibration of the lower part.
