magnetic separation basics - recycling today
Magnetic separation systems began appearing in scrap yards after World War II when heavy duty shredders used for grinding automobiles started to pop up across the United States. The early magnetic separation systems were mainly electromagnets; permanent magnets began making inroads when ceramic material became available and the cost to produce them decreased significantly, providing field strengths matching those of their electromagnet cousins. In addition, permanent magnets did not have to rely on an outside power source, and did not have the overheating problems associated with the early electromagnets, which were usually expensive and bulky
As the scrap industry evolved, magnetic separation systems evolved, too. By the end of the 1970s, three main types of magnetic separation systems were prevalent: the overhead magnet; the magnetic pulley; and the magnetic drum. And by the end of the 1980s, another form of magnetic separator, the eddy current, was becoming popular with both scrap processors and municipal recyclers. Although the eddy current will not be discussed here, its contribution to the recycling industry has been significant. An eddy imparts a magnetic charge to nonferrous metal material via a revolving, alternating-pole magnet usually under the conveying belt and in the head pulley. When the charged particle comes in contact with the field of an opposite pole, it is repelled and sorted
Today, magnetic separation still dominates the way processors remove ferrous from nonferrous material. While permanent magnets are popular choices, advances in electromagnets have made them competitive again
The first type of magnetic separation equipment is the overhead magnet. These are stationary magnets with self-cleaning belts that rotate around the magnet assembly. The cleated belt moves the attracted ferrous material and sorts it out of the magnetic field. These magnets can be configured in two main ways – parallel to the conveyor, referred to as inline; or perpendicular to the conveyer, referred to as crossbelt. Other configurations are actually variants of the overhead magnet where multiple magnets are used to transfer ferrous material from one magnet to another. These magnets are referred to as "multi-stage" magnets
In an inline application the magnet is normally positioned at the end of the conveyor above the head pulley. The main advantage to positioning the magnet in this fashion is that entrapment of ferrous pieces and particles is reduced. Material is freed once it leaves the conveyor belt and the magnet can pluck suspended ferrous material out of the air
If the conveyor is on an incline, the momentum of the particles leaving the conveyor belt results in an initial trajectory upward and toward the magnet. Thus, the material gets closer to the magnet and the ferrous particles have a better chance of getting picked up
"No matter how hard a processor tries to prevent entrapment, it is always going to occur with an overhead magnet," says one manufacturer of magnetic separation equipment. "But it is not going to occur as much in an inline configuration as it is with in a crossbelt arrangement."
It is especially tough to pull out ferrous from wet, shredded wood streams with an overhead magnet, because the shreds start to interlock and clump. Suppliers say that wet wood and any other wet material is more difficult to process, and should be avoided if possible when applying magnetic separation. However, an inline configuration can free up more of the ferrous material for separation
For inline applications, the magnet should be the width of the conveyor. Some manufacturers have square magnets. Others offer rectangular magnets where the longer length of the magnet is parallel to the conveyer, providing more coverage of the belt.
The other application for an overhead magnet is in the crossbelt configuration. This is a popular installation because placing the magnet inline over the head pulley is not always practical – there may be other equipment, such as a magnetic pulley or an eddy current separator, at the end of the conveyor. Plus, material recovery facility operators like the crossbelt configuration because the magnet can be positioned close to the hand picking stations, and because slower belt speeds increase the magnet’s efficiency
In both the inline and the crossbelt configurations, the overhead magnet is working against gravity, so it has to work harder and normally has to be more powerful than a magnetic pulley or drum. However, the inline setup requires less field strength than the crossbelt, because it does not have to combat entrapment, nor does it have to change the direction of the ferrous material. Therefore, an inline overhead magnet can cost less than one used in a cross-belt configuration
Variants of the overhead magnet include single- and three-stage magnets. In a single-stage magnet, ferrous material is carried through a magnetic field and offloaded onto another conveyor, while nonferrous material drops down into a container
In a three-stage configuration, the ferrous goes through three separate magnets that are contained in a single housing. When the ferrous material is transferred from one magnet to the other, the particles are flipped and any entrapped nonferrous material falls out, resulting in a cleaner end product. Both the single- and three-stage variants are powerful magnets that can pick up heavy pieces of ferrous metal
