Copper content reduces the value of scrap material in the ferrous foundry industry. Metal recycling facilities, therefore, look to provide certification on the scrap they provide to increase the saleable price per ton.  A Midwestern metal recovery facility installed their first copper detection system with General Kinematics components with success. As this customer looked to install another system in an Indiana facility, they turned to GK for technical support.
General Kinematics provided the first system with a Finger-Screen to remove the smaller size product, which the metal recycler found to be concentrated with copper and broken cast iron. This allowed for removal of the product prior to the copper detection system.  Providing additional flexibility, as well as off-line product introduction, was considered to be key objectives.
General Kinematics worked with the customer to provide an offline metering feeder, Finger-Screen with blank-off plates (not all scrap composition requires removal), and a liberating feeder to aid the sorting operators to remove copper or other valuable metals.
The customer now has the ability to run with the Finger-Screen blanked off, and trim the material going to the copper detection unit by adding ferrous fines to achieve an acceptable copper level.  Should the incoming (on-line) product mix be concentrated with copper, the finger decks can be utilized for further removal of fines, with further trim should it be deemed necessary.  The metering feeder can also be utilized for introduction of off-line material when the infeed of material is halted.
