In the 1990s, MAGNATTACK® (then known as WJB Engineering) was contacted by a large Aussie soup manufacturer to create a design for an inline liquid magnet. The design needed to be more effective, easier to clean, and more hygienic than a conventional finger pot magnet. The team went to work with the customer and developed a specialized range of inline magnet systems to meet their requirements

high-gradient magnetic separation for technical scale

Downstream processing still lacks efficient and integrated separation techniques. We present a high-gradient magnetic separation (HGMS) process for the successful purification of recombinant histidine-tagged Green Fluorescent Protein (His-GFP) from an E. coli cell lysate by means of superparamagnetic iron oxide nanoparticles functionalized with a pentadentate chelate ligand. The separator is an improved rotor stator prototype with 1 L chamber volume. Using 100 g of carrier, a purification performance of approx. 12 g His-GFP per hour could be achieved with an eluate purity of 96% and a yield of 93% for the whole process. We demonstrate how varying processing parameters enhances the final results and provide evidence of the potential of HGMS to become a real alternative to conventional downstream processes. These pilot scale experiments show that the combination of high performance nanocarriers and optimized separator design offers an attractive system for technical implementation. Almost no nanoparticle loss took place during the experiments. The demonstration of liter scale processing with nanoparticles is important because, due to their higher surface-to-volume ratio in comparison to microparticles, it is now possible to achieve higher capacities. Furthermore, the applied nanoparticles can be seen as low-cost, very stable carriers compared to common polymer microparticles

magnetic equipment guide -- eddy current separators

The description of an eddy current separator (ECS) sounds like the wrong answer to a science quiz: How can it use magnets to repel, rather than attract? And how can it affect nonmagnetic metals like aluminum?

Eddy current separators remove nonferrous metals such as aluminum, die-cast metal, and copper from nonmetallic material. Material is fed onto the conveyor belt of the separator, which moves it across the magnetic rotor where separation occurs. The two streams of material discharge into a housing which has a splitter to divide the nonferrous metal from nonmetallic material such as paper, plastic, wood, or auto shredder residue (ASR) – also called shredder fluff.

The key component is the magnetic rotor, which is a series of permanent rare earth magnets mounted on a support plate attached to a shaft. The magnetic rotor is surrounded by (but not attached to) a nonmetallic shell which supports the conveyor belt. This allows the rotor to spin independently and at a much higher speed than the nonmetallic shell and belt

magnetic equipment guide -- eddy current separators

When a piece of nonferrous metal, such as aluminum, passes over the separator, the magnets inside the shell rotate past the aluminum at high speed. This forms eddy currents in the aluminum, which in turn create a magnetic field around the piece of aluminum. The polarity of that magnetic field is the same as the rotating magnet, causing the aluminum to be repelled away from the magnet. This repulsion makes the trajectory of the aluminum greater than that of the nonmetallics, allowing the two material streams to be separated

When considering the purchase of an eddy current separator, there are four important areas to consider: type of material to be sorted, size of material to be sorted, material configuration, and burden depth

One of the easiest materials to separate is aluminum, due to its light weight and high conductivity. Copper can be separated because it has high conductivity, but it is more difficult than aluminum because of its heavy weight. Although they are nonferrous metals, stainless steel 302 and 304 are difficult to separate because of their high resistance to current flow. Die cast metal, or white metal, is another ideal candidate for eddy current separation. Its light weight and high conductivity allow the formation of high current and large force. There are other nonferrous metals, such as zinc, titanium, magnesium, bronze, and brass, which may be separable

magnetic equipment guide -- eddy current separators

A large piece of nonferrous metal will generate more current and therefore more force for repulsion than a small piece. Generally speaking, ½-inch and larger pieces are separable. Smaller pieces may be separable under certain conditions and depending on the type of material. Air resistance to the small pieces can make separation difficult or impossible because the eddy current force is so small

Nonferrous metal trapped in nonmetallic material may be impossible to separate. Small scraps of aluminum that are embedded or trapped in fabric, foam, or plastic usually are not recoverable. Copper wire covered with heavy insulation cannot be separated. And although aluminum cans are very easy to separate, a full soda can is not recoverable – the weight of the soda, or nonmetallic material, is much greater than the repelling force affecting the aluminum

It is important to load the separator’s conveyor belt as uniformly and as lightly as possible. If large surges occur, nonferrous metal will be under other material. This can weigh it down and cause a decrease in its trajectory, which may result in the piece not making it over the splitter and not being recovered

When using an eddy current separator on ASR, it is important to remove all possible ferrous metal from the material. Large pieces of steel can crush the wear cover of the rotor, and even small ferrous particles can accelerate wear on the rotor cover and the belt.

Auto shredders usually have one or two large diameter magnetic drums recovering ferrous after the car has been shredded. In addition, a magnetic head pulley should be installed. If large and strong enough, this pulley will remove almost all the ferrous material that is left

Manufacturers also use a variety of designs to ensure that the magnetic rotor is not damaged from any ferrous debris that remains in the burden. One manufacturer has patented a heavy-duty triple shell for the rotor; another uses a Kevlar protective layer. Other features that keep ferrous from getting under the conveyor belt and onto the rotor include a four-pulley arrangement for the conveyor or an eccentric configuration for the rotor and shell.

In eddy current separators with a concentric rotor design, the magnet is placed in the center of the outer shell (pulley) so that the alternating magnetic field encompasses the whole 360 degrees of the shell. In eddy current separators with an eccentric rotor design, the magnet is located off-center so that the magnet only touches on a tangent of the outer shell. This design can result in more efficient discharge of ferrous materials, since they leave the magnetic field sooner. Eccentric rotors are usually adjustable

In addition to recovering nonferrous metals from auto shredder fluff, eddy current separators are also used for applications such as separating aluminum cans from municipal solid waste (MSW); removing metal contaminants from plastics; extracting metallic contaminants from glass cullet; and concentrating metallics in electronic scrap

An eddy current separator is typically installed at the end of the processing line to remove aluminum cans from MRF residue. More heavy-duty eddy current separators are also installed at MSW plants to remove aluminum cans from garbage

Another application for eddy current separators is in removing contaminants from polyethylene terephthalate (PET) beverage containers. Shredded PET is processed over special eddy current separators to remove small, fingernail-sized aluminum fragments (from cans and bottle caps). Eddy current separators are also used to reduce metal contaminants in glass cullet

These applications often involve separating smaller nonferrous metals (less than 1 to 1/2 inches). These materials usually respond better to very strong eddy current fields (3,000 to 5,500 gauss in the operating zone) and/or higher frequency eddy current fields. To obtain stronger eddy current fields requires more rare earth (RE) magnet material in the rotor assembly, and strong, stable quality RE magnets are expensive. But these higher priced units generate increased nonferrous metal recoveries or more value, so the increased payback offsets the higher equipment costs. High frequency eddy current separators use more magnetic poles and are often driven at higher rotations per minute.

Some of the newer rotor designs incorporate curved rare earth magnets and up to 22 poles for a frequency of 28600. This type of rotor design is very cost effective and offers excellent performance in separating smaller particles

magnetic equipment guide -- eddy current separators

A typical eddy current separator will handle between 1 to 20 tons per hour per foot (TPH/F) of width; PET is 3/4 TPH/F, commingled MRF residue is 1 to 2 TPH/F, and glass cullet is 5 to 8 TPH/F. Product size, density or pounds per cubic foot, size and percentage of metals, and recovery required all affect eddy current separator capacity

To determine the size – and therefore the cost – of an eddy current separator, consider the type and density of the material, tons per hour processed (including average and peak rates), and specific information about the application. Additional equipment may be required to complete the system, such as a magnetic separator, vibratory feeder, transfer conveyor, holding bins, and material handling equipment.
