SCREW CONVEYOR ADVANTAGES
Several options and parts combinations are available for conveying a wide variety of materials in many different markets.
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.
No need for soft-start units.
Properly applied screw conveyors can handle product at very hot temperatures.
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.
