Used Zon Pack Screw Conveyors

Overview

Screw conveyors, or auger conveyors, move bulk materials using a rotating helical screw inside a tube or trough. They handle grain, powders, pellets, and waste in agriculture, food processing, mining and manufacturing. Select by capacity, screw diameter, pitch, material abrasiveness, inclination and sealing needs. They’re robust and simple but need correct alignment and protection from wear to keep performance and avoid blockages.

FAQ

What should I check when buying a used screw conveyor?

Check screw diameter, pitch, length, tube/trough condition, material of construction, motor and gearbox specs, bearing and seal condition, signs of wear or corrosion, shaft straightness, weld quality and any maintenance records.

How do I arrange shipping and on-site installation?

Plan transport for overall length—consider disassembly into sections, use a flatbed or enclosed trailer, secure lifting points and skids. Hire experienced riggers for unloading, alignment and reconnecting drive components on site.

What routine maintenance keeps a screw conveyor reliable?

Regularly lubricate bearings, inspect seals, check screw-to-trough clearances, remove build-up, monitor gearbox oil and belt tension, and replace worn flights or bearings before failure.
