Magnetic Separators

High intensity magnetic separator for use in pneumatic conveying lines. The Pneumag removes ferrous and paramagnetic contaminants from freeflowing powders conveyed at speeds of up to 25m/s. It purifies the transported product and reduces the risk of spark or piercing of filter sleeves. It is designed not to affect product flow.

Magnetic separation Wikipedia

Magnetic separation is the process of separating components of mixtures by using magnets to attract magnetic materials. The process that is used for magnetic separation detaches nonmagnetic material with those who are magnetic. This technique is useful for not all, but few minerals such as ferromagnetic (materials strongly affected by magnetic fields) and paramagnetic (materials that are less
