The collaboration between Goudsmit Magnetics, based in Waalre, Netherlands, and the German company Sortatec has produced a mobile metal separator that separates ferrous and non-ferrous metals from bulk material flows. The magnetic separator is easy to position correctly and is designed for coarse crushed material streams (such as shredded wood). Ferrous parts (such as nails, screws, staples, and hinges) as well as non-ferrous parts (such as door handles and strips) must be removed from the waste.

The result is three separate material streams—iron, non-ferrous metals, and clean (inert) bulk material—suitable for reuse. In addition to wood, the mobile machine is also suitable for construction and demolition waste, refuse-derived fuel, and industrial waste.

Operation of the goudsmit mobile magnet system

A spreading plate provides feeding and breaks up large volumes of material. This allows the material to be well distributed on an angled feed belt. This single layer is an ideal application for a band magnet, which pulls all iron components out of the stream and shifts them left or right as needed. After removing the iron parts, most of the material is transported to a two-meter-wide eddy current separator. A powerful 22HI rotor separates non-ferrous metals from the bulk material.

goudsmit mobile magnet system capacity

The metal separator has a capacity of 100 cubic meters per hour and is fed by a feed belt with a width of 2000 mm and speed control. The robust ferrite band magnet includes material guide chutes; the eddy current separator features a 2000 mm wide 22HI rotor with a speed of 3000 revolutions per minute. The height of both discharge belts can be adjusted hydraulically. The mobile unit is built on a single-axle trailer, suitable for public roads.

goudsmit magnetic separators can capture and remove metal contaminants from product streams.

Metallic foreign objects "contaminate" your products and may also cause serious damage to your machinery. Batch rejection is costly, but failing to remove foreign objects can be even more expensive, potentially necessitating product recalls. Examples of ferrous contaminants/foreign objects include iron, steel, or stainless steel fragments in raw materials, staples, nails and screws, loose bolts and nuts. Magnetic separators can filter/capture and remove ferromagnetic foreign objects from product streams to ensure high-quality products and prevent machine damage.

Why and when to usegoudsmit magnetic separatorsinstead of metal detectors?

Magnetic separators filter/capture (and subsequently remove) or immediately remove metal contaminants from product streams. Magnetic separators cause virtually no product loss and are suitable for removing frequent, large volumes of metal contaminants. Metal detectors are primarily used as a means to check for occasional metal contaminants or to remove non-magnetic foreign objects.

Metal detectors can only detect; to remove metal particles, the production line must be stopped, or a reject mechanism should eject the metal particles—which also removes product along with them (resulting in product loss).

Three reasons for installationgoudsmit magnetic separatorsThree Reasons

1) Magnets improve your product quality/purity

Contamination/foreign objects in food can lead to claims, very expensive product recalls, and reputational damage. Not only in food: even the smallest foreign objects are undesirable in pharmaceuticals, chemicals, or mineral bulk logistics and reduce the quality of the finished product.

2) Magnets prevent damage to production machinery

By placing magnetic separators at the inlet of production machinery (such as grinders, ball mills, pin mills, calenders, and crushers), damage to machinery and production stoppages can be prevented. Magnetic separators can very effectively filter out metal contaminants from bulk material streams. They operate continuously and provide a high level of operational reliability.

3) Magnets prevent dust explosions

Fine dust combined with oxygen and an ignition source can cause dust explosions. By filtering out metal particles from the product stream in advance, magnets remove a significant ignition source: metal-to-metal impact. This prevents serious injury (or worse), machine damage, and costly losses.

Many of our magnetic separators are suitable for use in ATEX 20/21 zones. As a certified manufacturer of ATEX equipment, Goudsmit has an externally certified quality assurance system that ensures ourmagnetic separatorsexplosion safety.
