Removal of Metallic Objects from Animal Feeds: Development and Studies on a new machine

A simple machine was designed by the authors to remove different metallic objects from animal feed stuff. A series of experiments were conducted to judge the efficiency of the machine whose results revealed that the device could remove almost 100% of magnetic metallic objects and 50-62% of non-magnetic metallic material from different feed stuffs. Metallic objects were more efficiently removed from wheat, barley and alfalfa than hay. The rate of removal of nails and wire pieces was higher than that of needles.
