Magnetic drum separator

Magnet makes blasting grit suitable for reuse

Magnetic drum separator

Goudsmit Magnetics recently introduced a magnetic drum separator for cleaning blasting grit. It separates contaminants, such as paint residue and rust, from magnetic blasting agent yet is also suitable for the separation of steel from non-steel blasting grit (such as ceramic material), which can then be used again. The blasting grit can become slightly magnetized during the separation and therefore block the blasting nozzle. To prevent this, a demagnetizer is used to remove the magnetism from the grit, thus preventing clumping of the blasting agent. After the grit has fallen through the demagnetization tunnel, it is sucked back through a hose to the blasting equipment where it can be used again. Use of a magnetic drum separator makes used grit suitable for reuse, extends its life and ensures that users do not blast clean surfaces with dirty grit.

Magnetic drum separator

The advantage of a magnetic drum separator is that the deferrization can take place in a continuous process. The product stream does not need to be stopped for removal of the magnetic particles. Moreover, the product makes direct contact with the magnet. The magnet attracts magnetic particles that are in the product. The attracted particles cling to the surface of the drum until they reach the underside, where the particles drop off and can be collected and carried away.


When it comes to bodywork, constructions, machines, tanks, wheel rims or bridges, these various products all have one thing in common, and thatís a process they undergo during production or maintenance: abrasive grit blasting. Blasting is a surface treatment of hard materials in which compressed air from a compressor is used to blast grit against a surface. This has an abrasive effect and removes rust, paint or other contaminants from steel, non-ferrous metals, asphalt, stony materials and other surfaces. There are thousands of different blasting agents that can help you achieve such an effect. Some examples are: sand, ceramic grains, glass bead, coal slag grit, cast iron grit or blasting grit.
