PRAB Shredder/Wringer Chip Processing System

Shredder/Wringer Chip Processing System | Reduce Metal Scrap Volume & Reclaim Cutting Fluids

Cut Scrap Volume. Reclaim Fluids. Increase Profit.

PRAB’s Shredder/Wringer Chip Processing System is a fully integrated, automated solution for processing metal turnings. Designed for high-output manufacturing environments, it significantly reduces metal scrap volume by up to 90% while reclaiming up to 98% of valuable cutting fluids and oils.

At the core of this system is the PRAB Shredder, engineered to handle long, stringy metal turnings (including aluminum, brass, steel, titanium, and more) and break them down into smaller, flowable pieces. These reduced chips are then conveyed directly into a high-efficiency wringer, where residual fluids are extracted for reuse or safe disposal.

This two-stage system transforms hazardous, messy metalworking waste into clean, dry chips that are easier to handle, safer to store, and far more valuable as recyclable metal scrap. It also lowers the cost of fluid replacement, enhances machine tool performance, and reduces plant slip hazards and safety risks.

Integrated for Greater Efficiency

PRAB’s Shredder/Wringer System is designed to integrate seamlessly with your production line and fluid recycling infrastructure. It can be paired with PRAB’s chip conveyors, coolant filtration systems, and wastewater treatment solutions for a fully automated chip and fluid management process. This reduces labor demands, minimizes downtime, and increases the consistency and safety of your operation.

• 📈 Fast ROI: Lower disposal and fluid replacement costs, higher scrap resale value

A Typical Shredder/Wringer Chip Processing System Includes:

• Infeed hopper with Screw Conveyor accepts chips and loose turnings, and meter feeds the turnings into the shredder.
• Turnings Shredder uses energy-saving dual shafts that operate by ripping, cutting, and tearing turnings into manageable, shovel-grade chips for further processing.
• Tramp Metal Separator effectively removes bar ends and other tramp metals from the chips, protecting the Wringer and other downstream equipment.
• Diagonal Shaft Wringer (available with air discharge or gravity discharge) efficiently removes moisture from chips with over 600 G’s of centrifugal force.
• The Wringer Discharge Conveyor transfers processed chips to the customer’s container (conveyor not shown in the above photo).
• A settling tank with a recirculating drag conveyor automatically recirculates settle fines back into the system. The package also includes an air-diaphragm pump for transferring fluid to the filtration system’s holding tank.
• The electrical control panel with an HMI Panel controls all system functions.
• An optional coolant recycling system can cut disposal costs by up to 90%. Learn about our Guardian Coolant Recycling System and Paper Bed Filter
• Optional auto lube systems for automatic greasing of bearings.

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.
