ABSTRACT:
The present invention relates to a method and apparatus of recovering by-product fines, such as coal fines, by-product fines created in the manufacture and processing of metals or any very finely divided substance which may be of value when recovered to a usable form and which may be naturally found in the form of a silt or as the result of the manufacturing process, from a slurry or sludge thereof. The slurry mass is first treated to dissociate it into discreet units, if required, for further treatment to recover the fines contained within the discreet units of the slurry in the form of a usable end product. The discreet units of the dissociated slurry are conveyed through a rotary-driven impeller feed conveyor and simultaneously a hot gas such as air or superheated steam is flowed through the conveyor in contact with the slurry segments or discreet units. This combined action of the rotary impeller feed and the flow of hot air uniformly breaks up and dries the discreet slurry units into particles of desired moisture content. If additional drying is required, the present invention teaches the use of a second rotary-driven impeller feed conveyor in which the extruded agglomerates are conveyed while again simultaneously flowing a hot gas through this second conveyor in contact with the agglomerate to break up or size and further dry the agglomerates to a desired degree.
