CP Group Releases First True Anti-Wrapping, Non-Blinding Screen for MRFs

CP Auger Screen sizes material by using a series of cantilevered augers that do not wrap or jam.

CP Group has launched a new screening technology called CP Auger Screen, marking the industry’s first true anti-wrapping, non-blinding screen for material recovery facilities (MRFs).

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, reducing the amount of manual sorters needed and increasing 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-inch stream and an under 5-inch stream while keeping rigid materials together. Keeping the rigids together plays an important role in the recovery of old corrugated cardboard (OCC) and chip. OCC has been increasing in volume due to the “Amazon effect.”

“This machine is unique compared to traditional disc screens,” said Terry Schneider, president and CEO of CP Group, in a statement. “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 more than a year at its facility in San Diego. The first three units are being installed in municipal solid waste (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 and demolition and commercial and 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.

The CP Auger Screen will be on display at WasteExpo, held April 23-26 in Las Vegas, at CP Group’s booth 2336.
