Product Portfolio
  • Metal Machining Scrap Equipment

  • PROCESS SCRAP METAL TURNINGS, CHIPS AND CUTTING FLUIDS

    PRAB offers a broad range of chip and fluid handling equipment to fit all metal processing applications. Starting with our full line of conveyors, PRAB equipment quickly and automatically removes scrap metal at the point of production. Removal of scrap and fluids away from your process allows for optimum production cycles and longer run times.

    If working with shavings, grindings, and turnings, PRAB engineers can work with you to put together a comprehensive chip handling system. Our Horizontal or Vertical Axis Crushers take large bushy wads of scrap and turn them into shovel-grade chips. PRAB engineers may recommend a wringer or briquetter to remove fluid from your metal. Processing metal in this manner offers you greater return for your scrap, less floor space required for moving and storing, and a cleaner, safer work environment. In addition, our engineers will work with you to recycle and reuse the spent coolant. Our complete line of coolant filtration units allows for solid/liquid separation and liquid/liquid separation, with finite filtration down to 1 micron clarity where needed. Contact a PRAB engineer today to learn more about how our complete chip and fluid management systems can save you money, improve your production, and meet your environmental and safety goals.

      • Turning & Chip Processing Systems

      • COMPLETE, TAILORED METAL AND FLUID PROCESSING SYSTEMS

        Turn your metal scrap and used cutting fluids from a liability into a revenue stream. Your operations run hard and lean. This means managing your process from raw material through production, and to recycle and reuse, is increasingly more important. A complete chip processing system not only automates waste management, it improves productivity, reduces harmful exposure of workers to injury, and reduces environmental and business risk.

        The processing of scrap metal begins with volume reduction. The often tightly wound metal turnings that are generated from various machining operations need to be safely and effectively crushed or shredded. To have optimum chip processing the metal must be in flowable, thumbnail size chips. To reach this point, scrap from milling, screw machines, Swiss machines, drilling, and other metalworking operations that produce long, winding metal scrap at high volumes must be reduced to chips. This is why we design and manufacturer Crusher and Shredder-based systems with integral conveyors and wringers for automated handling and fluid separation, filtration and recycling.

        PRAB's Dualpak briquetter increases the value of your metal chips, turnings and swarf by compressing it into solid briquettes. Augers feed chips into the briquetting press compression chamber. Then two opposing hydraulic cylinders press the metal, squeezing out the cutting fluid or coolant and creating a compact, up to 99 percent dry, briquette.

        Briquettes are easy to remelt, transport or store until you can get a better recycling price. You'll also maintain a cleaner, more environmentally friendly shop. The Dualpak briquetting press effectively handles a wide array of machine metals, including aluminum, steel, cast iron, copper, brass, titanium, magnesium and others.

        Choose from nine models to fit your application needs. Capacities up to 5,000 lb/hr (2 268 kg/hr) are available.  

      • Vertical Axis Crushers

      • REDUCE METAL TURNINGS AND BULKY WADS OF MATERIAL INTO SHOVEL-GRADE CHIPS

        Nested wads of metal turnings take up valuable floor space, are a safety hazard when sticking out of drums and bins, and offer reduced scrap value because recyclers have added costs for processing. Improving and automating the scrap management process begins with a crusher for volume reduction. The Vertical Axis Crusher is one of the most effective pieces of equipment for quickly and safely making flowable, thumbnail-sized chips from wads of turnings. The crusher can be a stand-alone unit or an integral part of a Chip Processing System. Other volume reduction equipment designed and manufactured by PRAB includes the Horizontal Axis Crusher, and Shredder.

      • Metal Turnings Shredders

      • IMPROVE SAFETY AND HOUSEKEEPING WHILE REDUCING THE VOLUME OF METAL TURNINGS

        The development of an automated scrap metal process begins with the volume reduction of metal turnings.
