摘要： A method for producing powder from a coarsely granular, thermoplastic material, comprising a homogenizing first device produces a first melt from a non-homogeneous pre-mixture of the material; first chips are produced from the first melt in a second device; the chips are milled to a powder; the powder is separated into at least two fractions with coarser and finer particle sizes; and a selected fraction with finer particle sizes is returned to the method prior to milling; wherein a second melt is produced from the selected fraction in a non-homogenizing third device, with second chips being produced from the latter, and the second chips are combined with the first chips and milled with each other.

摘要： The present invention relates to a roller cooling device for the continuous conversion of a hot flowable mass into solid chips by cooling, with at least one cooling roller, one crushing roller and one pressing belt, rotating via deflecting pulleys. The cooling roller and crushing roller serve for rolling out the mass into a thin film. The pressing belt runs on a part circumference of the cooling roller and serve for pressing the film against the cooling roller there. The parts are held from only one side and the rollers are mounted only on the same side and are driven from the same side, and in that said the parts are thereby accessible and/or demountable from the other side for cleaning purposes.
