I have a bunch of vibratory feeders from some factory that is being relocated to Mexico.
I tried one, not really knowing how it works. It promptly started vibrating. Amazingly, some rubber parts that were left in it by the previous owners, started traveling UPWARDS on the spiral, as the feeder was vibrating.
I do not really understand this, I would expect that parts would go down on an inclined vibrating surface, but they go UP. What gives? How do they work?
