Model FF Metal Separators Remove Metal Contamination

Aug. 16, 2011

Model FF Metal Separators are ideal for inspecting materials under free-fall conditions. These sensitive separators detect all magnetic and non-magnetic metal contamination including steel, aluminum, brass, copper, and stainless steel even when it is encapsulated in materials like plastic pellets.

Model FF Metal Separators provide protection for extruders, injection molding, blow molding, and fine grinding mills. This results in less mold and equipment wear and increases production uptime. Product purity is also improved, which is especially helpful with recycled plastics. When detected, metal contaminants are rejected through the “Quick Flap” reject unit, which can be rotated to match the position of the reject container.


Model FF’s automatic or manual product compensation allows flexible adaption to product conductivity and its enhanced signal-to-noise ratio minimizes susceptibility to electromagnetic interference and vibration. With its low installation height, the FF Metal Separator can be easily fitted into existing pipeline systems. Model FF Metal Separators are available in eight pipe sizes from approximately 1 to 9.2-in. in diameter.
