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.
