Abstract
A screen including a plurality of decks vertically stacked above one another, at least one of the decks bearing at least one sieve, the screen including means for vertically separating the decks from one another, suitable for selectively adjusting a vertical distance between each deck of the plurality of decks and at least one other deck of the plurality of decks.
Claims16
A screen for sorting pellets of a granular product by their respective particle sizes, comprising:
- a plurality of decks vertically stacked above one another, at least one of the decks bearing at least one sieve;
- a support frame for said decks;
- and
- a spacer for vertically spacing said decks out from one another, suitable for selectively adjusting a vertical distance between each deck of said plurality of decks and at least one other deck of said plurality of decks, comprising:
- an immobilizer for vertically immobilizing at least at least one of said decks relative to said support frame;
- and
- a plurality of inflatable support members, each defining a support surface for one of said decks in the vertical direction.
A screen for sorting pellets of a granular product by their respective particle size, comprising:
- a plurality of decks vertically stacked above one another, at least one of the decks bearing at least one sieve;
- a support frame for said decks comprising a plurality of vertical posts defining a space between them for receiving said decks, each vertical post having a bearing surface against at least one of said decks, each vertical post comprising a vibration absorber, defining the bearing surface, and said decks being translatable in the vertical direction relative to said vertical posts;
- and
- a spacer for vertically spacing said decks out from one another, suitable for selectively adjusting a vertical distance between each deck of said plurality of decks and at least one other deck of said plurality of decks.
A screen for sorting pellets of a granular product by their respective particle sizes, comprising:
- a plurality of decks vertically stacked above one another, at least one of the decks bearing at least one sieve, at least one of said decks comprising a rigid chassis, having an inner channel for the circulation of a fluid spraying the product, the deck further comprising at least one spray nozzle for spraying the fluid on the product, the or each nozzle being in fluid communication with said inner channel;
- and
- a spacer for vertically spacing the decks out from one another, suitable for selectively adjusting a vertical distance between each deck of the plurality of decks and at least one other deck of the plurality of decks.
