The Sand Recovery Unit has the function to receive the mixture of sand and water (dirty water) and return washed dry sand. The sand and dirty water are collected in a tank and injected, by means of a pump, to a cyclone where the sand is cleaned by friction produced in the contact with the inner surfaces and separated from the water thanks to the centrifugal force.
The sand is conveyed to a screen for a further drying treatment. The water coming out from the cyclone must be fed to a water treatment.
