Prab - Screw Conveyors
PRAB’s screw conveyors are compact, industrial screw conveyor systems designed for the automatic removal of metal chips and fines from CNC machining, turning, and milling operations. These systems use hardened steel auger screws to steadily propel scrap metal (swarf, bushy wads, or fine powders) out of equipment and into collection hoppers. Each PRAB screw chip conveyor is built for durability – with wear-resistant materials and robust drive motors that can handle continuous loads of abrasive chips. The enclosed auger design contains a mess and can even transport wet chips with cutting fluid.
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 means reliable metal chip removal that prevents backups, protects your machinery, and keeps your operation running smoothly. It’s a proven, heavy-duty solution to automate chip handling and reclaim valuable floor space and coolant.
