Inline processing of thermoformed scrap is not a simple and universal activity. If you are in need of a flexible solution for your size reduction activities, the Cumberland U Series of granulators is a good place to begin. Not only do they work as under or in front of the press units, but they come in a range of sizes that will allow any manufacturer or processor to accomplish their ideal results. The Cumberland 44U Thermoforming Granulator is the smallest in the series and yet features the same motor size and cutting circle as the other units. This machine has a 12" x 44" throat size and uses the motor to drive the feed roll. It sits on a castered base that has a profile low enough for under the press capture, but also for positioning in front of the presses too.
The materials enter through the throat and head into the working envelope. This contains the 3-knife Twin Shear rotor and two bed knives that ensure ideal processing. The rotor knives use a high angle design and interact with the 12" cutting circle in the bed to get flawless results. The frame is bolted and doweled, giving it a mobile and yet durable construction. This allows for the oversized feed rolls to function without fail, and for the 20-50HP motor to deliver predictable results. The materials are sent through the reversible screens that feature a range of sizes, which are easy to maintain due to their positioning in the pivoting screen cradle. The processed materials then exit the Cumberland 44U Thermoforming Granulator through the 8" pneumatic discharge. The anticipated throughput for this unit is around 816 kg per hour (roughly 1800 pounds), and it is controlled via NEMA 12 controls.
Standard features of Cumberland 44U Thermoforming Granulator can be upgraded with several standard options. These include the five blade open rotors, paddle rolls instead of the standard steel rolls, and upgraded controls and electronics. If you need a low profile thermoforming granulator, the Cumberland U Series can provide a very flexible solution. The 44U Thermoforming Granulator is ideally suited for those with smaller materials to process, but it can keep up with the larger units in terms of throughput and quality. It can be upgraded to allow for an affordable solution to size reduction needs, and is a good choice for many industries.
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
