Materials from micron size to bulky chunks can be handled by the 3/16-in. stroke of the HD feeder. Features travel speeds to 80 ft./min. (24 mtrs./min.) and throughputs ranging from 150 to 700 cu ft./hr. (4.25-20 cu mtrs./hr.). With unique Hi–Vi magnetic drive circuits, the feeders provide a simple yet powerful solution to challenging material feeding applications. Simple AC controls operate the feeders with precision. Standard models are available for most feeding applications. Special units can be ordered with multiple drives for greater capacities. A wide variety of standard and special trays are available.
