Flour, Maize & Rice Milling

PROTECT PRODUCT, BRAND & CONSUMERS BY FOLLOWING CORRECT MAGNETIC SEPARATION PRINCIPLES SPECIFIC TO MILLING OPERATIONS

The flour milling industry generally uses magnets in the following areas:

  • Intakes and first break – wheat & grain cleaning:
    • Removal of tramp and large metal pieces.
    • Prevention of dust explosion caused by metal entering high impact machinery.
    • Protection of damage to high impact machinery, e.g. first break roll.

  • Mid-process:
    • Protection of whiteners, color sorters (grain/rice), sieve and sifter conditioners, rotary seals, pneumatic transfer lines, etc.
    • Read more.
  • Final packing and bulk outloading:
    • Gravity bag filling.
    • Pneumatic transfer lines.
    • Read more.
  • Gravity bulk outloading.

Why does the SPHERICAL design win over conventional designs on effectiveness?

  • Strength: 11 - 12,000 gauss spherical element (most bullets and plate systems don’t exceed 7,000 gauss)

  • Coverage and retention of metal fragments: surface area at the back-side of the SPHERICAL™ element is key to the extraction and retention of weakly-magnetic fragments. The SPHERICAL™’s rounded belly means that the fragments are ‘washed’ around to the back-side of the ball/sphere and are retained behind the flow of the product. In comparison, the bullet magnets have a flat base or flat raised poles which often do not hold tightly enough to weakly-magnetic fragments.

The following grains require DURA-SLIK designs to ensure abrasion resistance is maintained and wear on the magnet surfaces is kept to a minimum:

  • Buckwheat.
  • Rice.
  • Dry corn.
  • Flax.
  • Kamut.
  • Millet.
  • Canola.
  • Durum wheat.
  • Hard red and hard white wheat.
  • Spelt.
  • Oats.
  • Triticale.

Important Considerations when Selecting a Magnet for Flour Milling Applications:

  • Is the magnet resistant to abrasion? What features allow for this to be controlled?
  • Can it be accessed easily for frequent cleaning?
  • Can the magnet be cleaned easily without risk of injury to the operator?
  • Will product-to-magnet coverage (+80%) as specified in current HACCP International Food Safety Standard 0909MAGSEP 1-2010 be sufficient, without causing any blockage?
  • Is the magnet certified by HACCP International and compliant to Food Safety Standard 0909MAGSEP 1-2010?
  • What means are used to reduce demagnetization over time?
  • Is the magnet supplied with proper certified documentation and compliance certificates?
