This matrix separator, equipped with a permanent magnet that can be activated and deactivated, can be used to separate ultra fine-grained magnetic particles, most smaller than 10µm, from liquids, usually with an extraction rate considerably higher than 80%.

A typical application is the treatment of degreasing liquids and baths in the steel industry. Nearly all steel companies have at least one high gradient permanent magnetic filter in operation, and thus the fluid circuit is almost completely closed.

Process water, minerals, degreasing baths and liquids, coolants.

A wire matrix is magnetised by permanent magnets that can be activated and deactivated (switched on and off). The ultra-high magnetic field gradients generated at the wires reliably capture the small iron particles and deposit them on the wires. After a few minutes, a strong flush cleans the filter matrix in just a few seconds. The resultant concentrate is usually processed into sludge by the

 wet drum separator NTS.
