Volumetric and gravimetric feeders for accurate and reliable feed of various products
Spirotech SRD Group Ltd manufacture a range of volumetric and gravimetric feeders, bespoke to suit your exact requirements, to accurately and reliably feed various powder or granular products.
Spirotech’s standard volumetric feeder design incorporates high and low level probes for basic hopper refill and the standard gravimetric feeder design incorporates loadcells for hopper refill and can provide continuous or batch weighing to suit your specific application. The gravimetric feeders can be used both as gain in weight or loss in weight feeder.
Mechanical rotating agitator standard on both product ranges
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.
