CUSTOM SCREW FEEDER SYSTEMS


Screw Feeders move a wide variety of material from bins or hoppers at a constant and controlled rate of flow. One or more tapered or variable pitch screws convey the material at the required rate. Screw feeders are available in a variety of types to suit specific materials and applications.


FEEDER VARIETIES

Multi Screw Conveyors are used as screw feeders and may consist of twin, triple, or quadruple screws, side by side. They provide a means of moving a wide variety of material from bins or hoppers at a constant and controlled rate of flow.

SCREW CONVEYOR ADVANTAGES

Extreme Versatility

Several options and parts combinations are available for conveying a wide variety of materials in many different markets.


Mixing

The normal rotation of the screw when conveying material also lifts and tumbles the product, which makes a screw conveyor an efficient mixer.


Simultaneous Conveyance in Two Directions

Combining right-hand and left-hand flights produces bidirectional conveyance.


Ready Reversibility

No need for soft-start units.


High-temperature Materials

Properly applied screw conveyors can handle product at very hot temperatures.


Abrasive Materials

Many special materials and hard-coating options are available to extend screw life in extremely abrasive applications.


Flood Loading Capability

Screw feeders are very efficient and reliable in regulating feed to downstream equipment. The screw diameter, pitch combination, pipe size, and flight configuration can be customized to solve specific bin unloading requirements.


Total Enclosure Screw Conveyor Systems

Completely enclosed systems protect the environment from the product being handled (dust-tight) and/or protect the conveyed material from the environment.


Multiple Inlets or Discharges

Intermediate inlets and/or discharges are readily added.
