Serpent & Dove has patented the ‘Acti-Grate’ system in which the tubes of a grate magnet ‘float’ and are activated by the flow of product around and between them. Grate magnets are used extensively throughout food, chemical and plastics industries to remove iron contamination from products. As some powdered or granular products may bridge and tend to block conventional grate magnets, the new system obviates the additional cost for external vibration to assist product flow.

Key features of the grate magnets include:

  • In the ‘Acti-Grate’ grate magnet system, each of the grate magnet tubes rests at each end on a fine edge within a larger diameter hole
  • The magnet grates allow the tube to float and be ‘live’ within limits
  • Product flowing over and between the tubes moves them enough to help prevent hang-ups and bridging
