The “right fit for the right job”!

Challenge

mixed-density-material-general-kinematics

A waste to energy facility in the New York area operates with a collection pit under the Boiler which is constantly filling with both wet and dry combined ash 24 hours a day. This ash is loaded out with a clamshell crane directly onto a General Kinematics Vibratory Main Ash Transfer Conveyor. The GK Vibratory Main Ash Conveyor directly feeds a GK Two-Mass Vibratory Grizzly Screen in-line which separates the “unders” from the “bulkies”. The “unders” are then metered by a GK Two-Mass Vibratory Feeder feeding an inclined belt conveyor to the metals recovery area for further processing.

Subsequently, an incline belt conveyor feeds a GK Two-Mass Vibratory Rod Deck Screen for a minus -3/8” separation before the Drum Magnet.  The plus 3/8” material is presented to a Drum Magnet to remove the ferrous metals from the ash. The ferrous metals collected at the Drum Magnet are then delivered to a GK Two-Mass Vibratory Fines Screen to remove any residual ash from the ferrous metals making a cleaner product.

The minus -3/8” ash material is bottom dropped through the Vibratory Rod Deck and taken out of the process. The remaining non-ferrous metals and ash are transferred by a series of GK Brute Force Vibratory Feeders before the flow is presented to an Eddy Current Separator where the non-ferrous metals are removed.  

Approach

Having used General Kinematics vibratory equipment on their site for over 20+ years without fail, this WTE company continues to utilize GK technology to assist with this challenging process. At this specific site, both the General Kinematics Brute Force and Two-Mass vibratory technologies are utilized to put the best fit application in service where needed. GK engineers understand the challenges with this type of material and fluctuations in material density, moisture levels, sizing variations, and throughput. Each project is reviewed specifically to ensure the “right fit of equipment is engineered & supplied for the right job”.   

Solutions / Results

GK has equipment successfully in service for over 20+ years and is able to provide both types of vibratory technology consisting of either Two-Mass or Brute Force style design. With this equipment in place, this WTE facility has operated their General Kinematics vibratory equipment reliably for over 20+ years. Both the Brute Force and Two-Mass are working well, and able to handle the demand. This customer now has both styles of GK Vibratory Feeders, Main Ash Conveyor, Grizzly Screen, and other Transfer Feeders for their material handling needs, with little downtime.
