Eriez provides a full line of metal separators specifically designed for the plastics industry
CF Press & Extruder Mounted Metal Detector/SeparatorThe CF Metal Separator is installed directly above the material feed throat of an extruder, injection molding or blow molding machine. It provides precision detection and removal of aluminum, brass, copper, mild steel, stainless steel and other metal contaminants from a slow, downward-moving column of material. Its robust, heavy duty design allows material feed systems to be mounted directly on top of the metal separation unit. It functions well with high levels of regrind & larger size recycled plastic materials.CFP Press & Extruder Mounted Metal Detector/SeparatorThe CFP Metal Separator is installed directly above the material feed throat of an extruder, injection molding or blow molding machine. It provides high sensitivity detection and removal of aluminum, brass, copper, mild steel, stainless steel and other metal contaminates from a slow, downward-moving column of material. Its design allows material feed systems to be mounted directly on top of the metal separation unit. The air activated slide and evacuation venturi assures the complete removal of metal contaminates. It is best suited for virgin materials with less than 15% regrind. FF Gravity Flow Metal Detector / SeparatorThe FF Metal Separator is used to detect and reject metal contaminates under free-fall conditions. It detects and removes aluminum, brass, copper, mild steel, stainless steel and other metal contaminates even when it is encapsulated in plastic pellets or shredded rubber. The reject mechanism can be rotated 360 degrees for operational flexibility. It is available in transit pipe sizes ranging from 1.2 inches to 9.8 inches.PN Pneumatic & Vacuum Metal Detector / SeparatorThe PN Metal Separator removes aluminum, brass, copper, mild steel, stainless steel and other metal contaminates even when it is encapsulated in plastic pellets. A specially designed quick reject mechanism operates effectively at vacuum or pressure conveying speeds up to 3936 fpm and 29 psi, without any interruption to the material flow. The reject mechanism operates rapidly to minimize the loss of good material. Contaminated material is discharged into a reject container that is emptied automatically.
