The principle of operation for Die Roller Extruder utilizes two rollers. The first roller is called the knurling roller and its job is to push the wetted feed material through the holes in the other roller which is the perforated die roller. The perforation size of the roller decides the size of extrudates, but the performance of the die roller extruder is defined by the sophistication of the perforated die roller design. Umang has many years of experience in refining these dies to succeed where our competitors have failed.

The extrudates are cut to finite lengths with the help of adjustable cutter within the perforated roller. The size of extrudates that is possible is 0.8 mm – 10.0 mm and capacities are up to and including multiple tons per hour.
