Compliance
PRAB Shredder/Wringer Chip Processing System help meet Federal EPA and ISO 14001 regulations and strict environmental compliance.
Health & Safety
The Shredder/Wringer Chip Processing System allows production to operate in safer work areas by reducing the volume of metal scrap which requires less storage space prior to recycling.
Low Maintenance
PRAB systems have the industry’s leading reputation as being dependable low-maintenance equipment with long service lives.
Value
  • Decreased storage and transportation costs
  • Increase value of scrap and fluids
  • Reduced labor costs

Process loose metal turnings into flowable chips. Scrap metal recycling system couples volume reduction with fluid separation to produce dry chips and reclaim 99% of valuable coolants and cutting oils.

The ideal solution for scrap metal consisting of flowable chips and loose turnings

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.
  • Wringer Discharge Conveyor transfers processed chips to customer’s container (conveyor not shown in above photo).
  • Settling tank with re-circulating drag conveyor provides automatic re-circulation of settle fines back into the system. Package includes an air-diaphragm pump for transferring fluid to holding tank of filtration system.
  • Electrical control panel with HMI Panel controls all system functions.
  • Optional coolant recycling system can cut disposal costs 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 maintenance required for manual greasing.

PRAB High Volume Aluminum Systems

Aluminum turnings are one of the most difficult types of material to process, especially in large volumes. PRAB delivers the reliable, durable, and dependable aluminum processing system your operations demand. The skid steer loader feeds wet, stringy material into the hopper of the 6” pitch steel belt conveyor. The PRAB Steel Belt Conveyor carries the material up and meters it into the crusher. The crusher reduces the stringy chips into smaller, flowable chips and discharges them onto the PRAB Drag Conveyor. The PRAB Drag Conveyor transports the material up and into two diagonal shaft chip wringers. The PRAB Chip Wringers separate the coolant from the chips using nearly 700 Gs of centrifugal force. The settling tank captures the coolant for recycling. An integral PRAB Drag Conveyor discharges the settled fines back into the material flow. The PRAB Chip Wringers internally generate air pressure to pneumatically discharge dry chips. The dry chips travel through the pneumatic piping and cyclones to the PRAB Magnetic Separator. The PRAB Magnetic Separator removes ferrous particles from the stream of material and discharges them into a container, while dry aluminum chips continue onto the weight belt. The weigh belt measures throughput of dry material in process and deposits it into a blower. The blower pneumatically transports the chips across the plant to one or more cyclones, which dissipate the air and deposit the chips into storage bunkers.

Blog: Setting The Groundwork For Equipment Performance & Return

The ability to recover valuable cutting fluid from metalworking scrap provides manufacturers the ability to reduce new fluid purchases and other related expenses like haul-away and disposal costs. Because the scrap is separated from the fluid the metalworking operation can also improve the value of its scrap going to the recycler. Companies weighing the options when purchasing new capital […]

Blog: Cutting Fluid’s Vital Role in Extending Tool Life

Cutting fluids play a very important role in metalworking by providing lubrication to the working area which decreases the amount of heat generated while cutting—preventing tools from exceeding critical temperature ranges. However, cutting fluid deteriorates over time as it becomes contaminated with tramp oils, metal fines, and bacteria. As it breaks down, it can damage machining tools, pumps, and […]
