PROCEDIMIENTO Y DISPOSITIVO PARA CLASIFICAR UNA MEZCLA DE PAPEL

Procedimiento para la clasificación de una mezcla de papel, en el que la mezcla de papel se tritura a un tamaño de grano en un intervalo de 40 a 100 mm, la mezcla de papel triturada se separa por medio de clasificación por aire en una fracción de productos pesados, que contiene papel de mezcla, y una fracción de productos ligeros, que contiene decoloración, y la velocidad de separación en el clasificador por aire es de 1 y 5 m / seg. The invention relates to a method for sorting a paper mixture according to which the paper mixture is sorted into a fraction of mixed paper and a fraction of deinking paper. The aim of the invention is to improve the sorting process in such a way that the quality requirements of the deinking quality can be reliably met and that the staff required for sorting is reduced. To this end, the paper mixture is reduced to a grain size of approximately 40 to 100 mm and the reduced paper mixture is separated by air separation into a heavy fraction that contains mixed paper and a light fraction that contains deinking paper at a separation speed of approximately 1 to 5 m/sec. The invention further relates to a device for sorting a paper mixture that allows fulfillment of the quality requirements of the deinking quality and that can be carried out with a reduced number of staff. To this end, a disintegrator for disintegrating the paper mixture is provided. Downstream of said disintegrator an air separator for separating the disintegrated paper mixture into a heavy fraction and a light fraction is mounted. Said air separator has a classification cross-section that can be adjusted to a separation speed of between 1 and 5 m/sec.
