This magnetic separator protects valves from damage

| By Chemical Engineering


This company has launched its first DMN Magnetic Separator demonstration unit (photo). The new range is designed to remove sub-micron metal contamination (including particles of 304 and 316 stainless steel) from dry, free-flowing products, such as sugar, grain, flour and other granulates and powders during processing. Theseparators will help to increase the life of rotary-valve vanes and blades by preventing metal contamination from entering the unit and causing damage. The ideal location for a DMN Magnetic Separator is as close to the rotary valve as is practical. The magnetic material incorporated into these units reaches a product contact strength of 10,000 Gauss. The easy-clean design allows the separators to be safely and quickly cleaned by removing the magnetic cores from their fully welded 316 stainless-steel tube housings. All units can be ATEX certified for use in Zones 20, 21 and 22 or in gas Zones 0, 1 and 2. — DMN UK Ltd., Calne, Wiltshire, U.K.
