PRAB Dualpak^™ Briquetter

Proven to Increase Scrap Value Up to 25%

Exclusive Dual-Ram Compression Technology

PRAB’s Dualpak^™ Briquetter machines increase the value of metal chips, loose turnings and swarf by compressing them into near solid, dry briquettes 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 industry’s densest briquettes.

Capture up to 99% of expensive coolant and cutting fluids.

Create more dense and uniformly shaped briquettes with dual compaction.

System Benefits:

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

Standard Features:

PLC controls with HMI operator panel
Position and pressure feedback 0-10 volt DC
Fluid containment tray with coolant recovery pump
Swivel discharge conveyor rotates to fill multiple containers
Fan-cooled heat exchanger
System capacity up to 14,000 lbs/hr

“We get $0.17 per pound more for our briquetted material over loose chips.”

– Jack Rovan, Martin-Baker Plant Manufacturing Manager

The Industry’s Densest Briquette

System Operation:

Augers feed chips into a compression chamber, then two opposing hydraulic cylinders press the metal, squeezing out any fluid and creating a compact puck. System is available with 1,2,3, and 4 cubic yard live bottom hoppers and can also be adapted to compress swarf.

Systems with dual feed hoppers are available

1/2 Yard infeed hopper includes two 3” augers

Dualpak Briquetters help keep the shop clean

Live bottom hopper includes multiple 6” augers
