FINGER-SCREEN™ | ASR Processing Case Study

 by General Kinematics,


In 2021, OmniSource, an ASR recycling facility located in Toledo, Ohio, identified that their existing two trommels had reached the end of their service life and needed to be replaced. They decided to investigate alternative solutions to the trommels because of their longstanding issues with pokers, jamming, and maintenance costs. The alternate solution would need to eliminate these problems while maintaining or improving their recovery rates.



OmniSource has a longstanding relationship with General Kinematics and often collaborates on their equipment development to create solutions for common scrap handling challenges. In search of a replacement for the trommels, the facility manager approached General Kinematics to inquire about GK’s screening technology. After working closely with the Omnisource team to identify requirements and current challenges, GK suggested the FINGER-SCREEN™ For Metal Recovery as their solution. OmniSource agreed that GK’s screen was the ideal replacement for their trommel. They were confident that the screen’s durability and separation capabilities would meet their expectations. 



The General Kinematics FINGER-SCREEN™ For Metal Recovery was purchased, designed, and installed in OmniSource’s current auto scrap recovery processing system. GK’s FINGER-SCREEN™ uses vibratory action to separate materials coming from the shredder. The FINGER-SCREEN™ is a heavy-duty answer to durability issues often seen when screening scrap materials using a trommel. The screen was designed to fit in the same footprint as their existing trommel, which reduced installation costs. 



OmniSource installed the FINGER-SCREEN™ in November of 2021. After a few modifications and adjustments, the screen performs as intended and has eliminated jamming and prevented pokers from entering the chutes downstream. The material recovery sizes are meeting the customer’s expectations. Due to the unit’s success, Omnisource has purchased a second screen and plans to replace the remaining trommel later this spring.


“General Kinematics and OmniSource have had a great relationship over the years. GK’s proven track record of providing heavy-duty equipment with conservative designs made them an easy choice to collaborate with for the trommel replacement project. Changing screening technologies on one of the biggest ASR plants in the US was not a decision that was taken lightly. GK once again delivered a piece of equipment that will provide a long-term, low-cost operating solution.”
