Magnets can prevent animal suffering. Every year, a lot of cows are injured after having ingested sharp, metal objects that entered their ration. By installing magnets in the mixer feeder wagon, these metal objects can be filtered out of the feed. Trioliet offers a variety of magnets in its product range: 1. an auger magnet, 2. suspended magnet rods above the conveyor belt (or chain) 3. a magnet strip on the discharge chute of the side discharge door.
