No, it is not. But it is the ideal solution for free flowing or frangible materials. There are many ingredients that cannot be fed effectively with vibratory drives and to this end, we offer a complete line of single and twin auger, agitated feeders, which are up to the task with the toughest materials. A quick and easy test to see if a vibratory feeder would work for you, would be to take a small amount of material in your hand. Make a fist, squeeze, and open it. If the material is packed together like a snow ball, a vibratory feeder would not be suitable.
