Model AVC -Vibrating Grizzly Feeder

Vibrating grizzly feeders, mod. AVC, are used in primary rock quarry installations where the material is of large dimension mixed with a high percentage of fine parts. The machine is particularly suitable for dry materials or in any case with negligible percentages of moisture. Mainly made up of a rectangular casing, of which the bottom is sealed, for about half of its length, by thick wearing plates, while in the remaining part some bars are mounted forming a grizzly that allows to select the material removing earth and fine parts which otherwise could overfeed the crushing machine. The support of the vibrating frame is realized on helical springs. A vibrating unit placed under the casing gives the oscillations to the machine. The amplitude of the oscillations, therefore the capacity, can be adjusted.
