Case Study: Trommel System vs. GK’s FINGER-SCREEN™

 by General Kinematics,



Sorting - recycleChallenge

Trommel systems are sold as a turn-key solution and are portable. They are reasonably priced and most components are already made so lead time is very quick. However, there are many issues with blinding, or material not screening properly, that are often associated with trommels.


GK was asked by a customer to give a presentation as to what we could do to make the system better and run more efficiently, utilizing our equipment. We knew that our equipment alleviates many issues connected to the use of a trommel and it was time to go to work to show just how much the FINGER-SCREEN™ could improve their process with their own data.


First GK studied the maintenance and reliability of the FINGER-SCREEN™ Primary Screen compared to that of the trommel. Next up, was durability. Before general issues were reviewed, such as balancing to reduce floor loading, the long-lasting decks were found to be proven many times in the past, and more robust than the trommel system. Lastly, energy consumption was compared with the diesel-powered 125 HP motor that is used on the trommel unit. The FINGER-SCREEN™ Primary Screen excelled in maintenance, durability, and balancing. Even the energy costs were considerably lower.


The customer decided to purchase the GK FINGER-SCREEN™ Primary Screen based not only upon the data they had been presented, but the overall innovation to their process that only General Kinematics could provide. Our team is made up of sales engineers that understand equipment from conception to implementation. GK is dedicated to improving processes around the world. The FINGER-SCREEN™ Primary Screen is a shining example of GK’s vision for the future. Are you looking to improve your process? Give GK a call and let us show you the difference GK can make.
