Abstract
PURPOSE: To perform classification and washing simultaneously with one unit by feeding sea sand transversely by oscillations while it is held sieved to two steps, large and small, pouring washing water for rough washing, intermediate washing and finish washing thereto from above, extracting the water in the tanks below these and receiving the refined sand at the other end.
CONSTITUTION: In a method of washing and desalting sea sand by inclining sieves upward to the right, rough sieves 10 are provided on the upper steps of washing sieves 8c, 8b, 8a. The sea sand supplied to one end thereof is sieved while it is fed transversely by oscillations. It is successively sieved down onto washing sieves 8c, 8b, 8a of the lower step. Shells and ballasts of large grains are fed transversely on the sieves 10 of the upper step and are discharged from the other end as off-grade sand for concrete. On the other hand, washing water is scooped after the finish washing of the sand from above and below the sieve 8a at the sieve terminal. It is again scooped up after the intermediate washing of the sieve 8b and is used for rough washing of the sieve 8c.
