Challenge

General Kinematics was given a challenge. A screen for sizing limestone was sitting over 100 feet in the air atop a silo. Due to the difficult access point, it needed to be replaced with a reliable screen that did not get jammed or need maintenance often. The inquiring company sent their material to GK to be tested as well as four GK competitors.

 

Approach

General Kinematics loves a tough screening challenge, over the last 60 years of innovations and field experience, GK developed a finger deck capable of self-relieving sticky materials. Our experts in the GK R&D Lab knew this screen would be a perfect solution.

 

STM SCREEN

Solution

The lab results proved GK’s theory that the finger decks would separate the limestone better than a normal punch plate deck over a mesh screen. Due to the softness of the fines mesh, screens tended to jam up. This led GK engineers to design the STM-SCREEN™ Two-Mass Vibratory Screen with a large finger screen deck staggered over a smaller finger screen allowing materials to wriggle free in either deck.

 

Result

The GK STM-SCREEN™ Two-Mass Vibratory Screen was installed on top of the silo and is running smoothly. It has decreased downtime and required fewer trips to the top of the silo. The maintenance team is happy with their new screen and improved processing power.
