Abstract
Abstract Apparatus comprising a vessel, means for compacting material and supplying the compacted material to the vessel, means for breaking-up the compacted material and spreading the broken-up material in the vessel, means for supplying gas to the vessel, and discharge means for discharging material in compacted condition, such discharge means including a discharge opening and flap means causing material to be discharged therethrough in said compacted condition. A rotatably driven platform divides the vessel into communicating retention and discharge chambers and controls the passage of material from the retention chamber to the discharge chamber; and the retention chamber is connected to the material and gas supplying means and contains the material breaking-up and spreading means, while the discharge chamber is provided with a large, offset, discharge opening and contains a scraper movable thereover.
