Screw Conveyors (Augers) – Efficiently Move Metal Chips with Proven Reliability

PRAB screw conveyors are advanced-engineered to handle abrasive, dense metal chips with ease. Heavy shafts, hardened flights, and replaceable liners reduce wear and extend life—often doubling longevity compared to lighter builds. Each system is engineered and manufactured in the USA, and for our European and international clients, produced and supported from PRAB’s EU headquarters in Poland, ensuring the same high quality, efficient logistics, and technical expertise across continents.

PRAB screw conveyors offer efficient collection, transfer, and metered feed of wet or dry metal scrap and chips across machining and fabrication processes. Designed for reliable performance with minimal maintenance, these conveyors are ideal for feeding downstream equipment, such as shredders, crushers, or chip-processing systems, in CNC machining cells and heavy production environments. Their robust build and precise scrap movement help maintain throughput while managing coolant carryover and minimizing plant-floor housekeeping.

Maintenance is minimal, as there are no belts to break; our sealed bearings and auto-lube options keep the screw turning reliably with little intervention. For machine shops and production lines, implementing a PRAB screw conveyor ensures reliable metal chip removal, prevents backups, protects your machinery, and maintains smooth operation. It’s a proven, heavy-duty solution to automate chip handling, reclaiming valuable floor space and coolant.

The PRAB screw conveyor is available in a wide range of sizes with many options depending on the type and form of material, storage, and recycling needs.

  • A load hopper may be built to fit the needs of the application
  • Dual augers
  • Customized trough materials
  • Auto lube systems for automatic greasing of bearings.

Image Right: Auto lube systems are designed to automatically supply a small quantity of clean grease or oil to bearings on a regular basis, improving bearing performance and eliminating the maintenance required for manual greasing.

Choosing the right conveyor depends on five variables: scrap form, fluid content, abrasiveness, volume, and layout.

  • Use a Steel Belt Conveyor for mixed, sharp, heavy, hot, or abrasive scrap, and when you need long-term durability.
  • Use a Pivot Belt Conveyor for thin-gauge, oily, or sticky stamping scrap that tends to cling to belts.
  • Use an Oscillating Conveyor for gentle, horizontal chip or scrap movement, especially machine-side or in-pit transport.

Rule of thumb:

  • Versatile & heavy-duty: Steel Belt

  • Sticky/oily stamping scrap: Pivot Belt

  • Horizontal chip transfer: Oscillating
