Permanent Magnetic Overband
Recycling, quarrying and havy industries continue to benefit from metal contamination extracted by use of Permanent Magnetic Overband units. These units can be placed above flat or trough type conveyors. Large permanent magnetic packs generate deep penetrating magnetic flux fields that attract and remove "tramp" type steel items. This design of unit is considerably cheaper to purchase and run than electro-magnetic units. The only power consumption required is to power the geared drive. When considering installation points, it should be noted that steel belt support rollers will need to be changed to non magnetic ones due to possible flux field absorption.
