A Silo is an accessory which can be used along with a vibratory bowl feeder for providing higher capacities. Usually, the number of components which can be loaded in a vibratory bowl feeder is constrained by the weight and the volume of the components. In order to increase the loading capacity, usually auxiliary hoppers are provided. The disadvantage of auxiliary hoppers is the extra space which they occupy and plus the extra cost and electrical consumption and wiring required for the same. As against this, Silos offer the advantage of increased loading capacity and they do not require any Electrical Supply. The increase in height is also nominal. The overall table size also does not increase to that extent. Though the Silo has a lot of advantages, the only disadvantage is that it can only be used for certain components like needles, rollers etc. It cannot be used for components like screws, hooks etc. The Silo sits on top of the bowl and is an integral part of the vibratory drive unit.
