This is a used, Vibra Screw vibrating bin/hopper and stainless steel screw feeder system. The stainless feeder is fed by the top bin and vibrated by two vibra screw electric vibrators, model VE3/36/120. One vibrator works the hopper/bin and one works at the base of the feeder to ensure product continues to move. This machine is also equipped with a round vibrating baffle at the bottom of the bin/hopper to help evenly distribute your dry solid into the below screw feeding system.
These particular units were feeding sodium bicarbonate as a dry sorbent injection system into the hot flue gas duct of a coal fired power plant to react with S02, S03, HC1, HF and some NOX. This process is a pollution control technology that is very cost effective. Sodium bicarbonate is none hazardous material. These units could be easlily cleaned and re-purposed for your application.
