PRAB’s Dualpak™ metal scrap Briquetting Machines turn metal chips, loose metal turnings, and metal swarf into highly dense, near-solid briquettes. Using two opposing hydraulic cylinders, PRAB’s exclusive “dual compression technology” delivers unmatched performance, producing the driest, most compact aluminum, steel, cast iron, and other metal scrap pucks on the market. This results in greater efficiency during remelting and more value when recycling or feeding to the furnace.
Unlike standard briquetting machines, PRAB’s Dualpak™ Briquetter compresses from both sides, ensuring consistent density and dryness across every puck. These highly compact scrap pucks are easy to transport, store, and re-melt, giving you:
With nine models designed for various capacities, PRAB’s Dualpak™ Briquetters handle machining metals like aluminum, steel, cast iron, copper, brass, titanium, magnesium, and more. This makes PRAB’s machines versatile for any metalworking or CNC operation.
Advantages of PRAB’s Dualpak™ Briquetting Machines:
PRAB’s Dualpak™ Briquetting Machines compress metal chips into dense pucks and extract residual cutting oils and coolants. This efficient fluid recovery system enables you to reuse up to 75% of the extracted coolant, significantly reducing the need for new coolant purchases. By recycling and reusing your cutting fluids, you can cut costs, minimize waste, and improve your shop’s environmental sustainability while optimizing your metal scrap processing.
The Dualpak™ Briquette Press is available in nine models to handle different capacities and various machining metals, including aluminum, steel, stainless steel, cast iron, copper, brass, titanium, and magnesium.
Features of the PRAB Dualpak™ Briquette include:
Options include:
*Note: live-bottom hopper sizes are available: 1, 2, 3 or 4 cubic yard capacities

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.

PRAB Builds Equipment for the Toughest Jobs in Manufacturing and Metalworking
If you’re generating wet chips and sending them straight to the recycler, you’re paying to have the extra weight removed. Briquetting helps you recover that expense, as well as your cutting fluids. Sometimes gravity just isn’t enough. No matter how long you allow chips to drain, a fairly substantial amount of cutting fluid remains, adding weight to the material you’re […]
