ABSTRACT:
A sieve apparatus containing a circular sieve or screen, possessing at a portion of its circumference an impervious region. The impervious region of the circular screen forms a trough in which there can be formed a liquid sump for washing the material which is to be treated. In the case of a circular sieve or screen, formed of perforated sheet metal, the impervious region can be free of holes or openings. If the circular sieve or screen is formed of a sieve or filter material, then the circular sieve is covered at the impervious region. Spray tubes or the like serve for spraying the circular sieve, the material which is to be treated and for forming the liquid sump.
