Abstract

See full text

An apparatus for washing and grading sand includes a first vibrating screen having a deck arranged to receive a feed material. Oversize material passes over the deck of the first vibrating screen for collection as a first product, and undersize material and water are collected in a sump of the first vibrating screen before being pumped to a hydrocyclone. A second vibrating screen receives an underflow from the hydrocyclone upon a deck thereof, with oversize material passing over the deck of the second vibrating screen for collection as a second product. An overflow from the hydrocyclone passes into a settling tank, and a water storage reservoir receives water overflowing from the settling tank while sludge is collected and removed from a lower end of the settling tank. Water is passed from the water storage reservoir to the first and second vibrating screens to wash and fluidise material thereon.
