operation • Sand and water mixture to be separated

conveyed through an inlet placed on the top of the machine through a pump, air lift or by gravity • Sand settles in the lower par t of the truncated cone tank • Sand washing for the separation of the organic par ticles

from the sand itself with water injection and slow mixer • Sand conveyed through a thick spiral • Inspectionable tank in order to ensure effectiveness and easy maintenance • On demand, sand washing system device

complete with blowers, piping, exclusion valve and diffusers for the separation of the organic

par ticles from the sand.
