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.

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.

Research has shown that top-performing machine shops annually invest two to three times more money in capital equipment than other shops. Not coincidentally, profit margins for high performers are almost double those reported by typical shops. For all businesses, the objective is to achieve the largest possible profit margins. One way for metalworking operations to attain that goal is […]
A4 CHALLENGE With the combination of the briquetter and a crusher ahead of it, the company was able to efficiently and significantly reduce the bulk density of its scrap material. Instead of dumping the contents of the hopper directly into an outside container, the forklifts now deposited the scrap material into the briquetter, which uses dual compression […]
