Single Screw Feeders

Single Screw Feeders or Metering Screw Feeders also known as Volumetric Feeder are designed to continuously meter all materials from flushing powders to fibrous particulate products at a constant volume to high accuracies.

Single Screw Feeder

Single Screw Feeders Principle and Operation:
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 consists of a batte designed, 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. Resulting in material being metered out at a constant volume of between ±1% to ± 2%. For output capacities see choice of feeder section below or follow link to the feeder sizing tables.

Single Screw Feeders Choice of Feeder:
The selection of the correct type of feeder from the extensive batte range is determined primarily by the type and specification of the material to be handled. 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.
Tapered Conditioning Chamber de-aerates fluidising powders or livens cohesive materials ensuring screw runs completely and evenly filled.
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.
Single Screw Feeders
Moving parts kept to a minimum with no drive chains or couplings, resulting in low maintenance requirements
Output Range - 1.0kg/hr to 100,000 kg/hr.
