摘要:
An apparatus for washing and grading sand and aggregate includes an aggregate grading and washing screen with a plurality of vertically stacked decks for producing a plurality of aggregate products therefrom, and at least one sump for collecting undersize material comprising sand and water from the plurality of decks. A plurality of sand washing and grading units each include a first hydrocyclone, a vibratory screen having a deck, and a sump beneath the deck for receiving undersize material and water passing through the deck. The deck of the vibratory screen receives an underflow from the first hydrocyclone. A further hydrocyclone receives undersize material and water from the vibratory screen's sump. Underflow from the further hydrocyclone is delivered onto the deck of the vibratory screen. The first hydrocyclone of each sand washing and grading unit receives undersize material and water from the sump of the aggregate washing and grading screen.
