General use of magnetic separation in food industry is removing rare earth elements<br />

from food ingredients. Similar to the ore beneficiation or desulfurization, the target<br />

substances are weakly magnetic <strong>and</strong> need high magnetic fields applied to a continous<br />

process of food production line.<br />

Bunting <strong>Magnetic</strong>s Co. offers magnetic metal separators <strong>and</strong> metal detectors for the<br />

quality of food <strong>and</strong> extended service life of the processing equipment, especially for<br />

cheese processing, chocolate plants, pet food processing, flour mills, spice plants,<br />

vegetable processing. Removal of both ferrous <strong>and</strong> nonferrous tramp metals is achieved<br />

by their line of food safety products for the food processing industry (For more<br />

information visit www.buntingmagnetics.com). Figure 8, 9 <strong>and</strong> 10 show case studies<br />

from Greenwood <strong>Magnetic</strong>s Ltd. (For more information visit<br />
