Mechanical rotating agitator

As standard, both feeder options incorporate a mechanical rotating agitator to act as a bridge breaking device to aid positive discharge before entering the screw conveyor. The rotating agitator is a very efficient method for handling cohesive powders prone to bridging and rat holing. Also, a mechanical rotating agitator minimises fluctuations in bulk density, in comparison to air or vibratory discharge aids, which is an important factor when considering a gravimetric feeder as variations in bulk density distort the accuracy of the feed rate. A screw conveyor is used to control the feed rate from the feeder and offers transfer rates from 25kg/hr up to 3000kg/hr. The feeders can be manufactured from carbon steel, grade 304 stainless steel and grade 316 stainless steel, with options also, for ATEX Cat 3D feeders suitable for use in a ATEX  Zone 22 area. As standard the feeders are supplied with a hopper storage volume of 100ltr however the capacity can be tailored to suit your specific capacity requirements.
