SandTec is designed to recover fines and ultra-fines present in the slurry coming from aggregates washing plants. Compactness is one of the key feature of SandTec, which has been conceived for uses in which the feeding material oversize is minimum. It guarantees the recovery of about 90% of fines over 75 microns, the almost total elimination of clay and lime impurities, the recovery of materials with a residual moisture below 15% and the reduction of the solids presenting the discharge water with reduction of materials to be treated in the water treatment plants.
