Magnetic separator or metal detector?
About magnetic filtering, magnetic separation, several ways to remove metal foreign bodies from your product streams. Magnetic separators remove metal foreign bodies from your product streams. Metal foreign bodies ’contaminate’ your product, and they can also cause severe damage to your machinery. Rejection of batches is costly, but it can be even more costly if the foreign bodies are not removed, making it necessary to conduct a product recall. You will then be faced with huge costs and reputation damage. Examples of metal contaminants / foreign bodies: staples, nails and screws, bolts and nuts that have vibrated loose, wear of the moving steel and stainless steel machine parts and rust particles (corrosion). Magnetic separators filter and remove metal contaminations from your product streams, in order to guarantee high product quality and prevent damage to machines. Magnetic separator or metal detector? A magnetic separator filters/traps (and later removes) or immediately removes the metal contaminants from the product flow. Magnetic separators cause practically no product

Magnetic separator for lithium battery powder
Goudsmit has recently produced a rotating magnetic separator for the metal-free processing of lithium-ion powder for batteries, to guarantee optimum quality of cathode powders; nickel, cadmium and lithium. Any metal contamination present in the powder reduces the quality of the material mix and leads to a battery’s short life. The automatic cleaning rotating magnetic separator filters metal particles as small as 30 µm from the poorly flowing lithium powder. Lithium is extracted from salt lakes such as the Salar de Atacama in Chile, where there are huge reserves of brine containing lithium. Some large producers process this lithium into a powder that serves as a raw material for batteries used in electric cars, laptops and mobile phones, among other things. Operation The magnetic separator contains nine strong, rotating magnetic bars that prevent the fine powder from sticking to the bars like a bridge. The rotating movement ensures that the product does not block on the bars, so that good deferrization is possible. The contact with the magnetic bars is therefore optimal. This is important because weakly magnetic particles in particular must touch the magnetic

Magnetic filter for paper pulp
Goudsmit Magnetics has recently made a series of magnetic filters that are suitable for removing baling wire from paper pulp. These steel wires hold bales of cellulose together and –when everything goes as it should– are removed before t This is done in an automated process followed by human inspection. In practice, the process is never perfect and steel wire still occasionally ends up in the paper pulp. This causes damage to the pulp processing equipment, as well as production downtime. Placing a magnet in the paper line prevents equipment damage, downtime and therefore significant losses. MAGNETIC FILTER The magnetic filters for paper pulp have a large bore for product flow, ranging from DN100 to DN400. This passage is completely surrounded with very strong magnetic bars with a high flux density (also referred to as the Gauss value), making it possible to capture the steel wire even at a relatively high flow rate. In addition, the magnetic insert is fitted with a sturdy guide and pneumatic rods, which simplifies handling for operators. This is not only ergonomic but also ensures that regular inspection takes place.” It is surprising that magnetic filters are not yet standard in paper lines.

Rotating magnet cleans powder without stopping production Goudsmit Cleanflow drawer magnets are magnetic grid separators with strong neodymium magnetic bars. They filter small ferrous contaminants (down to 30 µm) from powders and granulates in free-fall and low-pressure transport pipes.
Rotating magnet cleans powder without stopping production
Goudsmit Cleanflow drawer magnets are magnetic grid separators with strong neodymium magnetic bars. They filter small ferrous contaminants (down to 30 µm) from powders and granulates in free-fall and low-pressure transport pipes. Goudsmit Magnetics, based in Waalre in the Netherlands, recently launched a rotating Cleanflow magnetic separator suitable for installation in free-fall lines in a continuous process. Cleaning takes place without stopping the product flow - an explicit request from a customer who wanted to recycle cans of milk powder in a continuous process. During the cleaning cycle, the magnets stay in the product flow. This guarantees the user that no iron falls back into the product during cleaning, something that was regularly a problem with other systems. The unit can be used in the chemical, ceramic, plastic and recycling industries, among others. In the latter case, it is used to make plastic or rubber granules metal-free. Operation The magnetic bars in the Cleanflow magnetic separator filter metal particles and paramagnetic particles from 30 µm out of powders and granular products. The separator is suitable for high capacity product flows (up to approximately 60 m3/hour)

The value of magnetic flux density for magnetic separators
The operation of a magnetic separation system is often judged with magnetic field measurements. But this is not the whole story. We often determine the degree of operation of a magnetic separation system using magnetic field measurements. In that case, we measure the magnetic flux density at one or more places in the separator. Determine separation capacity We regularly use these measurements – consciously or unconsciously – as the only measure for the separation capacity of magnetic separators. In specific situations, these measurements can provide a sufficient picture thereof, such as for determining the decrease in magnetic force – and therefore separation power – of a specific separator over time. Or to compare the performance of two or more of the same types of separators that are used under the same process conditions. More than flux density measurements In general, however, this is not the case and we have to include more aspects than just flux density measurements when determining the separation power of a magnetic separator. This is explained in this document.

Dangers of Neodymium magnets; magnetic fields and more
Neodymium magnets are very strong, which leads to magnetic and mechanic dangers. These magnets are brittle and easily broken, causing sharp fragments. Neodymium-iron-borion or Nd-Fe-B magnets, are marketed by Goudsmit under the brand name Neoflux®. These magnets are very strong. Neodymium magnets smaller than one cent are powerful enough to lift over 10 kilograms. As a result, these magnets are also dangerous, as they can pinch the skin or fingers when suddenly attracted to iron or steel. Sharp fragments Neodymium magnets are made with special powders and coatings and are therefore brittle and easily broken. They can easily break at temperatures above 150 ºC or when they slam together. When they break, this occurs so suddenly and violently that flying pieces may cause eye- or other injuries. Damage to appliances Neodymium magnets should always be kept far away from electrical appliances, magnetic (bank)cards, old (deep) monitors, pacemakers, watches, etc., because otherwise they can cause permanent damage to these devices.

Solae removes metal contaminants from soya powder residue with a magnet Remove very small stainless steel and iron particles
Solae removes metal contaminants from soya powder residue with a magnet
Remove very small stainless steel and iron particles Solae Belgium N.V., a Dupont company, recently introduced a new type of magnetic separator in their powder line; the Easy cleanflow magnet from Goudsmit Magnetics of Waalre (NL). This magnet checks soya powder for metal contaminants, such as stainless steel wear particles. The metal particles get into the product as a result of friction at the dryer drum and are absolutely undesirable. No operator needed Solea`s design requirements for the magnetic separator were that no operator would be required and that cleaning of the unit could be performed safely and efficiently. The unit also had to be dust-tight, food-proof and fitted with food-safe EC1935 seals. The magnetic separator placed under the vibrating sieve meets all the requirements and removes minuscule metal particles and weakly magnetic stainless steel particles as small as 30 µm from powders.How the magnet works. Stainless steel particles Solae is a food producer and, among other things, they process a residue
