In fact, the hammer mill should be equipped with a heavy particle trap and a magnet to separate the feed from stones, glass, and pieces of metal that might enter the machine causing damage, a risk of explosion and poor pellet quality. Ventilation air required for the milling process is sucked in by an opening in the rear of the heavy particle trap.
