CP Auger Screen

Fractionate for Downstream Efficiencies

The CP Auger Screen™ is a first of its kind machine used as a primary fractionating screen in single stream. It diverts 60% or more of the inbound material away from the traditional presort.

MRF Design Revolution

We actively listen to your needs and develop innovative solutions to address your challenges. CPG’s creation of the Auger Screen revolutionized the design of Material Recovery Facilities (MRFs), placing us at the forefront of MRF design and technology innovation.

The introduction of the Auger Screen to the market enables our customers to eliminate the presort process, reduce manual labor, and enhance safety and overall system efficiencies.

Correcting the Process Flow

In our industry, people have always protected the machines. Industrial automation should work to have machines protect the people. This is what the Auger Screen does. By placing the screen prior to any manual sorters, you have safer, fewer and more productive people.

Eliminate the Presort

The presort is the most dangerous sorter position in a MRF. Sharps, biohazards, glass, needles and other materials hidden under a large burden depth of material move quickly creating a dangerous and dizzying position. When these sorters need to slow down the line to remove large items, system productivity goes down.

Our solution to this problem is to eliminate the presort.

The CP Auger Screen™ is a first of its kind machine used as a primary fractionating screen in single stream. It diverts 60% or more of the inbound material away from the traditional presort. Less material on the belt means less people needed. Cut your presort manual labor by half or more when you install a CP Auger Screen.

Versatile Non-Wrapping Screen

Utilizing a sequence of cantilevered steel augers that resist wrapping and jamming, this screen efficiently sizes material while demanding minimal maintenance. Designed to accommodate high volumes, it is suitable for various applications at various stages in the MRF – at the frontend of the system or as a sizing machine downstream.

Primary Separation Solution

CP Group completed a total system upgrade at Cal-Waste in Galt, California that involved adding a Primary Auger Screen. Dave Vaccarezza, owner of Cal-Waste, says the Primary Auger Screen, “takes the burden depth down to a much more manageable level and does a great job of spreading everything out so there are no big lumps and clumps.”

It also allowed Cal-Waste to reduce the number of sorters on the Auger post sort line from eight to four. Additionally, the MRF increased its capacity from 11 to 30 tons per hour.
