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.

The PRAB metal screw conveyor is available in 6″ to 24″ diameters, designed to convey materials ranging in various weights and bulk densities. Configurations can be either horizontal or at an incline.

A metal scrap conveyor is a system used in manufacturing to transport metal chips, turnings, swarf, and other waste for recycling or disposal. Common types include steel belt, oscillating, drag chain, magnetic, pneumatic, and specialty conveyors—each chosen based on scrap size, abrasiveness, coolant content, or temperature. These systems improve efficiency, safety, and the value of metal scrap while preventing downtime.
PRAB metal scrap conveyors are engineered for 30+ years of continuous operation—with documented installations exceeding 40 years. Systems handle up to 2,000 lb/hr of scrap and integrate seamlessly with metal chip processing and coolant recycling systems. Known for their low maintenance and durability, PRAB metal handling systems are trusted by automotive, aerospace, die-casting, CNC, and heavy manufacturing plants worldwide.
