Bunting targets wood recyclers.

* Magnetic head pulleys and other conveyor separators from Bunting Magnetics Co., Newton, Kan., are being marketed as a "first line of defense" against ferrous contaminants for wood recyclers.

The Bunting head pulleys use permanent magnets--high-density ceramic or optional rare earth magnets--to separate ferrous debris from intermediate wood material by holding the tramp iron and embedded metal scrap against the conveyor belt and allowing it to fall away from the underside of the conveyor after the clean wood products have been discharged.

The pulleys also feature a radial magnetic field designed to eliminate dead spots and cover the entire working surface of the pulley for more thorough separation. The company says the head pulleys are also "completely self-contained, self-cleaning, and virtually maintenance free."

Bunting says its Suspended Plate Magnets and Cross-Belt Separators are also frequently used in wood recycling applications. Both mount just above conveyors to pull tramp iron from the moving material. They are frequently used in combination with the company's head pulleys to achieve more thorough contaminant removal. They capture tramp iron from the top layers of material while head pulleys remove the tramp iron located closer to the belt surface.

Bunting Suspended Plate Magnets consist of large plate magnets suspended from support cables or from an optional floor-standing metal frame. The Cross-Belt Separator is basically a small electrically driven conveyor with a cleated belt wrapped around a large plate magnet suspended by cables. From a maintenance standpoint, the main difference between them is that Suspended Plate Magnets require manual cleaning; whereas, Cross-Belt Separators are fully and continuously self-cleaning. The Cross-Belt Separator's high-energy ceramic magnet reaches deep into the product flow and captures ferrous scrap even from fast-moving conveyors. The tramp iron falls from the unit's cleated belt as it moves the contaminants out of the magnetic field and into the collection area. The self-cleaning feature makes the units ideal for use where high concentrations of ferrous contaminants are expected.

Bunting also offers an extensive line of electronic metal detectors designed to work individually or in tandem with its magnetic separation equipment to sense and remove both ferrous and nonferrous metal contaminants.
