The frame structure is made of steel channel with the fully enclosed sieve box suspended at its four corners on rubber bushes. The box consists of two decks with ball cleaned sieves. The vibrator drive is located in the center of the machine. The vibratory movement of the sieve increases both the capacity on a given sieve-surface and the sieve effect.
