Abstract

A highly efficient dry sorter (1) for continuous operation has a conveyor belt cover (4) with longitudinal grooves, with the corresponding conveyor surface arranged obliquely in such a way that the coarser coal runs off over the grooves while the finest coal or substance remains in them. It is thus possible for the finest coal to be extracted from the top while the coarser granules are removed by the lower longitudinal side. The belt conveyor (2) is given the necessary permanent tilt by the fact that to the underside (16) of the conveyor belt cover (4) are allocated edge supporting strips (17, 19) designed to correspond to supporting rollers (22, 23) arranged at a distance along the bearing frame (3). These supporting rollers (22, 23) are supplemented by pressure rollers permitting the even securing of the edge region on both the upper and the lower longitudinal side (20). Dry fine coal is sorted with a high throughput rate and can be further processed without any drying, thus giving rise to the minimum outsize quantities, as tests have shown.
