Materials that must be a certain size have to be screened. Bank material is dumped onto
a vibrating screen which will separate it into two or more products.
Stones that do not fit through the top screen (generally termed "oversize")
are sent into one stockpile while smaller material falls through and can be stockpiled
separately or (in the case of multideck screens) land on lower deck screens and separated
further.
Double-Deck Vibrating Screen sorts gravel into various sizes
