’Fraggy’ to the rescue

Archiv – UK-based Master Magnets has designed, manufactured and delivered a 7.8-tonne magnetic drum for an end-of-life vehicle (ELV) processing plant in Belarussia. UK-based Master Magnets has designed, manufactured and delivered a 7.8-tonne magnetic drum for an end-of-life vehicle (ELV) processing plant in Belarussia.
Korpak JSC, which is located in the Belarussian capital Minsk, purchased a second-hand ELV plant from Scotland in 2005. A drum had to be replaced and Korpak approached Master Magnets for a high-efficiency, heavy-duty solution that would offer a long working life. Master Magnets recommended a fragmentiser electro-magnetic drum – known as a ’fraggy’ drum – which was of similar dimensions to the model to be replaced.
‘€˜Fraggy’€™ drums continuously separate ferrous from non-ferrous material; an internal 180deg stationary electro-magnet and an alternating magnetic pole arrangement spin the feed material and allow non-magnetics to fall free. Only ferrous material is carried over the drum, thus preventing non-ferrous material from becoming trapped. The heavy-duty cover revolving around the electro-magnet consists of a couple of armoured 8mm-thick manganese covers.
Other features identified by Master Magnets include: an advanced air-cooling system to reduce the operating temperature of the magnetic coil and increase its working life; and higher magnetic intensity owing to the improved cooling system and the internal magnetic arrangements.
Master Magnets has supplied ‘€˜fraggy’€™ drums for over 30 years, with magnetic drums in full operation at more than 100 sites worldwide, including China and Australia.
