... 959,909. Gravity - separation apparatus. NIKEX NEHEZIPARI KULKERESKEDELMI VALLALAT. June 6, 1962, No. 21948/62. Headings BID and B2H. A conveyer belt sedimentation plant has a conveyer belt 15, Fig. 1, arranged to be provided with a trough-shaped cross-section along part of its upper run constituting a depositing section (see Fig. 4), followed by a trickling section where the belt has an upwardly-curved cross-section (see Fig. 5) and where liquid 30 discharges at right angles, and terminated by a further section for conveying the liquid-free solids where the belt has a trough-shaped cross-section once more, Fig. 7. The solids are removed from the belt by a separating plate 25, Fig. 1. Where some solids are of higher density than the remainder, a recess may be provided in the edge of plate 25, to permit such solids to be discharged to a washing and sedimentation device 27, 28. Further separating plates may be placed above plate 25 to separate stratified solids according to grain size and ...
