The CD-XXL™ C&D Recycling System is a medium to high tonnage Construction & Demolition (C&D) recycling system designed for highly effective recovery of material. Systems include primary and secondary screening, metals separation, air classification, and primary and secondary pick lines. Each system can be custom designed to meet your recovery objectives. The CD-XXL™ System is engineered to process up to 450 yards per hour (344 m3 / hr.) or more.

The heart of the system begins with GK’s vibratory FINGER-SCREEN™ Primary Screen followed by a picking line, typically called the A-Line for the over material. Further processing of the unders is achieved on the B-Line with metals recovery, secondary screening, and GK’s DE-STONER® Air Classifier. Options for the C-Line and D-Line include optical sorting or further fines and lights processing. Contact GK’s Recycling specialists for more information.
