Eriez, of Erie, Pennsylvania, USA, has released its new, heavy-duty Model CF Metal Separator, which can be installed directly above the material feed throat of an extruder, injection molding machine, or blow molding machine. It removes both magnetic and non-magnetic metal contaminants from a slow, downward moving column of material, reducing machine downtime and costly repairs and improving product purity, the company says, adding, "Even the smallest metal particles in molten plastic can result in a loss of production and expensive damage to extruders, injection [machinery,] and blow molding machinery. The cost of repairing a screw or barrel damaged by just one larger piece of metal is enormous compared to value added for a Model CF Separator. This metal separator delivers excellent operational reliability, even at high throughputs."

The company says that the Model CF Metal Separator features automatic self-calibration and monitoring. "It is a fully automatic separation process with adjustable scanning sensitivity and reject duration. The Model CF works so quickly that metal particles are constantly removed from free-falling granulate not only at the initial fill, but also at subsequent top-ups. The metal contamination is discharged into a reject container with a fast acting, air-powered separating slide." Model CF Metal Separators are available in four pipe sizes from approximately 2.9 to 5.9 inches in diameter.
