Vibrating Feeders Made in S235JR, AISI304, AISI316 or Wear-resistant steel

VIBRATING FEEDERS

GVF Impianti vibrating feeders are constituted by a vibrating canal, which can be coated by wear-resistant materials, activated by two adjustable eccentric en-masse electro-vibrators.

The vibration impressed to the canal generates the directional flow, at controlled speed, of the material in the machine.
The unit is comprehensive of a structure with suspension springs, containment sides with interchangeable plates subjected to wear and a fast flow regulation shutter.
The vibrating feeders can be supplied in different configuration depending on their usage.

The vibrating feeder “A” series are used for the secondary continuous, weighed and dosed feeding of every machine (belt conveyors, screeners, mills etc.) thanks to a regulation valve and to the vibrators’ eccentric masses.
