The CP Auger Screen sizes material by using a series of cantilevered augers that do not wrap or jam due to their corkscrewing motion, making it extremely low-maintenance. Any material that could wrap, such as hoses or plastic film, are released off the end of the auger.
Its low-wear augers are made from abrasion-resistant steel, making them durable while requiring little to no maintenance.
When placed in front of the presort, the CP Auger Screen dramatically decreases the volume on the presort. This decreases the amount of manual sorters needed and increases sorter safety by removing the small hazardous fraction. With decreased volume on the presort, manual sorters work more efficiently.
When used as a scalping machine, the CP Auger Screen fractionates the stream into an over 5" stream and an under 5" stream while keeping rigid materials together. Keeping the rigids together plays an important role in the recovery of OCC and chip. OCC has been increasing in volume due to the "Amazon effect."
Terry Schneider, President and CEO of CP Group says, "This machine is unique compared to traditional disc screens. The cantilevered augers convey large flat materials over, while fines and flexible fiber go through to the unders, and the remainder goes to the side. What really sets it apart is that it does not wrap. The auger rotors act like a corkscrew, conveying any stringy materials over the side. There is a lot of interest in this machine for those reasons."
CP has been developing the machine and running the prototype for over a year at their facility in San Diego, CA. The first three units are being installed in MSW facilities this summer, and several more are sold and in production.
The CP Auger Screen can be used in various applications including MSW, Single Stream, Construction & Demolition, and Commercial & Industrial. The largest model can handle 35 tons per hour of inbound single stream material, 60 tons per hour of commercial, and 80 tons per hour for construction and demolition.
