Abstract: Granulation of materials, particularly materials in stranded form, employing a rotatable cutter with multiple feed channels at different elevational positions along the periphery of the cutter. The granules of the feed material formed by the cutter are collected without further, unwanted cutting by using a separate, pressurizable discharge channel for each feed channel or by providing voids in the cutter through which the granules can fall, desirably with the assistance of feed channel applied pressure.

Abstract: A drying apparatus for solid materials such as granulated plastics materials comprise a plurality of conveying channels which are arranged in a stack in which the air travels from the bottom of the stack to the top of the stack. Each conveying channel is formed by air supply ducts in such a manner that the top of a duct simultaneously forms the bottom of the next above conveying channel portion whereas the bottom of a duct forms the top of the conveying channel portion. All channel portions are connected in a meandering shape, whereby the interconnecting elements are curved screens through which air may laterally escape.
