For high-volume recyclers, Guptail suggests using a
finger screen to make a primary cut of nominal 8-to- 10-inch material, sending the overs material along to a picking line and the material under 10-inches on to the unders line, where a magnet will recover the ferrous material in the stream.
The conveyor moves the waste onto a vibratory "
finger screen," which further loosens the waste and sifts out finer materials before they are again conveyed by two diverging belts up to the two primary picking line conveyors.
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.
At the heart of every Erin Fixed C&D Recycling System, is Erin's patented

After larger objects are picked out by a hydraulic material handler operator using a grapple, material is loaded onto a steel-belted conveyor made by Ptarmigan Machinery, San Antonio, and then heads to a vibrating

A
finger screen is comprised of vibrating rods or "fingers" placed at a downward angle.
Sherbrooke designs systems using its welded Z-pan apron conveyor, which meters material on to a General Kinematics
finger screen. Sinram says this method helps to improve sorting efficiency on the overs line.
Guptail recommends a
finger screen for primary sizing.
Glavin says
finger screens further assist in copper recovery.
