Metering Screw Feeder also known as Volumetric Feeder is designed to continuously meter all materials from flushing powders to fibrous particulate products at a constant volume to high accuracies. The basic feeder have unique tapered conditioning chamber, complete with a slow rotation agitator and variable control functions, which provides timed on /off settings, constant or intermittent operation, to suit the nature of the products being handled.
Product is directed into a variable speed metering screw, which runs completely and evenly filled and is linked to an electronic feed back drive ensuring accurate speed holding under all load conditions.
Both single and twin, screw feeders are equally as efficient, with the single screw mechanically simpler and therefore, more economical and is the prime choice where practical. Both units share the following features and benefits
Large inlet eliminates material bridging.Suitable for use with very fine to coarse, or fibrous, particulate products.Easily removable front cover provides a safe and quick access for cleaning.Instant release of feed screw without shaft seal disturbance.Ideally suited to industries that require rapid clean down and product changes.
