Abstract

The invention relates to a setting machine for processing fine and fine coal with a setting bed in rectangular shape with a feed device on one side of the rectangular setting bed and a discharge device on the other side, which are arranged on the long sides of the rectangular setting bed. It is significantly longer transversely to the direction of movement of the fine coal than in the direction of movement, in particular between 1.5 and 2.5 m long. It has a hydraulic discharge device for discharging the mountain particles from the lower part of the jig and is composed of individual cells.

The disadvantage of this known setting machine is that the fine coal is between 1.5 and 2.5 meters long. It is that with her, because of the - in the direction of movement it has surprisingly been found that a Fine coal seen - only slightly larger width setting machine, which is transverse to the direction of movement of the than the length of the bed, no high throughput rates - fine coal is much longer than in the direction of movement gen can be achieved. The separation effect is also 65 direction, whereby it is in the direction of movement of the fine coal not satisfactory, because when using fine coal it is between 1.5 and 2.5 meters long, enough to by supplying the raw coal to be processed, a good separation of the mountain particles from the fine not charred until just above the perforated bottom of the settling bed.
