Description of the Cumberland 56U Thermoforming Granulator (U-Series)

Manufacturers in need of thermoform scrap processing often find it challenging to get a machine that can provide inline applications in precisely the right location. The Cumberland U-Series Thermoforming Granulators are designed specifically to meet this specialized demand. The mid-range model Cumberland 56U Thermoforming Granulator features a 12" x 56" throat that can easily manage up to 2200 lbs (998kg) per hour thanks to its excellent design and reliable rotor. Additionally, it has a low profile base that allows for positioning under the press or in front of it, and which uses a motor driven feed roll to tackle jobs of all kinds. The Cumberland 56U Thermoforming Granulator features a 103" x 73" working envelope that contains an oversized cutting circle (12" in diameter) and a three knife open Twin Shear rotor. This partners up with the two bed knives (reversible D2 for long life and optimal efficiency) to process materials in a uniform and reliable manner. The 20 to 50 HP motor is controlled by NEMA 12 controls, and will help to maintain the continuous pace that most manufacturing processes demand. The materials are put through the selected screens, and these are reversible for long use and affordable operation. This indicates that the Cumberland 56U Thermoforming Granulator has been designed to provide owners with a good solution, but also to keep operating costs under control. The reversible knives and screens (crafted from high quality materials) ensure that wear and tear does not translate to hefty upkeep costs - even with continuous usage. Maintenance on the machine is relatively simple as well, thanks to the pivoting screen cradle, the bolted and doweled construction, the easily accessible rotor, and the convenient 8" blower system.

In addition to good design and rugged performance capabilities, the Cumberland 56U Thermoforming Granulator can also be equipped with a few standard options. These include paddle rolls instead of the standard steel rolls, upgraded controls and electronics, and five blade open rotors. When a low profile thermoforming granulator has to be part of your manufacturing process, the Cumberland 56U is a very flexible choice. It can be used "as is" or upgraded to meet specific needs. This granulator can be positioned in the most convenient area of your press, including under the press, and will consistently deliver reliable results. As "compact" granulators go, the Cumberland 56U granulator delivers full-size performance with affordable convenience.


  • The two pivoting doors offer complete access into the bottom of the cutting chamber (screen cradle and screen). The larger 12" (305mm) cutting circle and open screen area allow maximum throughput.
  • Two swing open doors allow easy access to the screen cradles and screen.
  • The 3-blade open rotor with Twinshear cutting geometry offers quieter, cooler operation and is ideal for polypropylene.
  • Pneumatic upper hopper opening allows for easy access. Rotor and bed knives are easily accessed by tilting open the upper chamber.
