FLIGHT CONVEYER FOR PRELIMINARY DEHYDRATION OF MATERIAL BEING TRANSPORTED Russian patent published in 1997 - IPC

Abstract RU 2082661 C1

FIELD: concentration of minerals; dehydration of coal in flight conveyers. SUBSTANCE: projections are welded to separate links of flight chain. When such links pass through roller of end head, insignificant impact occurs and consequently material is subjected to shanking; as a result, partial dehydration of material takes place. Fine fraction is removed by scrapers of conveyer specially provided for the purpose. Cleaners are made from flexible material, for example from rubber. Cleaners are tightly pressed to screened cloth facilitating pouring out of fine fraction. EFFECT: enhanced efficiency. 5 dwg
