Value
  • Higher scrap value
  • Decreased transportation costs
  • Easy to re-melt, transport, and store
  • Optimized container fill

Superior dual ram compression technology for producing the industry’s densest scrap pucks.

PRAB’s Dualpak Briquetting Machines increase the value of metal chips, loose turnings and swarf by compressing them into near solid, dry briquettes for scrap metal recycling to send to the recycler or feed to furnace. Unlike competing briquetting machines, the Dualpak uses two opposing hydraulic cylinders. These cylinders press metal equally from both sides, creating the driest, most compact scrap pucks on the market.

Briquettes- or scrap pucks, are easy to re-melt, transport or store giving you more floor space, optimized container fill, cleaner shop and more value from the scrap dealer until a better price is available for scrap metal recycling. You’ll also maintain a cleaner, more environmentally friendly shop with a briquette press. Dualpak briquetting machines are available in nine models to handle different capacities and a variety of machining metals, including aluminum, steel, cast iron, copper, brass, titanium, magnesium and more.

Advantages of the PRAB Dualpak™ Briquetter include:

  • PRAB’s Exclusive “dual compression technology”
  • More efficient re-melt
  • Optimized container fill
  • Increased value of metal scrap
  • Maintains a cleaner, more environmentally friendly shop
  • Pucks are easy to store
  • Pucks transports easily
  • Easy to install
  • Easy access to dies minimizes downtime
  • Ability to fill multiple containers

PRAB DualPak Briquetter Animation

Briquetters reduce machining scrap moisture content and simplify handling, allowing shops to get more money from the scrap dealer and to save on coolant. The PRAB Dualpak Briquetter uses superior dual-ram compression technology for producing the industry’s densest metal scrap pucks. Pucks are easy to re-melt, transport or store which frees up more floor space. They also optimize container fill and create a cleaner shop. The PRAB Dualpak Briquetter handles a variety of scrap including aluminum, steel, cast iron, copper, brass, titanium, magnesium and more.

Material is introduced to the live bottom feed hopper. Multiple feed augers move material into the feed process. Material is picked up by the cross-feed auger. The cross-feed auger sheers material and feeds it to the incline auger. The incline auger feeds material to the vertical charge augers which meters and controls the quantity of material fed into the compression chamber. When the vertical charge augers reach the full condition, they disengage, and compression begins. The door punch moves in for final compression. The finalized puck drops onto a conveyor, which can be custom designed for the system.

 

How the DualPak Briquetter Works

PRAB’s Dualpak Briquetter makes it easy to remelt, transport or store scrap metal briquettes until you can get a better recycling price. You’ll also maintain a cleaner, more environmentally friendly shop, and reclaim valuable machining fluids.

Machining operations can benefit from briquetting. PRAB Dualpak Briquetters compacts metal chips and swarf into near solids cylindrical briquettes that can be efficiently remelted increasing the value of your scrap. The risk of smoke or fire is greatly reduced because up to 99% of all fluids both hazardous and non-hazardous have been removed. Here’s how the Dualpak Briquetter works. First, metal chips are loaded into the chip hopper. Augers located on the floor to the side and in front of the metal chip hopper transport the chips from the hopper to the infeed auger. When the chips arrive at the infeeder auger a meter volume of chips are feed into the compression chamber. Once the chamber is loaded, two opposing hydraulic cylinders are actuated, and the metal chips are compacted into a dense consistent briquette. During the process, residual fluid is removed due to the intense pressure exerted on the chips and is collected into a containment tray. After the compression cycle has completed, the newly formed briquette is ejected from the compression chamber onto the discharge conveyor.

 

The DualPak Briquetter In Action

PRAB’s Dualpak Briquetter processes metal chips into a solid briquette for volume reduction and fluid reclamation.

 

PRAB Aluminum Swarf Briquetter

PRAB’s Dualpak Briquetter processes aluminum swarf into solid briquettes.

In July 2014 PRAB, Inc. acquired the PuckMaster assets in order to bring together the best in briquetting technology and material handling under one brand. PRAB supports all existing PuckMaster installations worldwide. Customers with PuckMaster briquetting machines that need service should contact the PRAB customer service department.
