Sifting device for screening of a stream of material and method for operating a sifting device

摘要

The present invention relates to a sifting device (10) for screening of a material stream, comprising at least one static or dynamic classifier (14, 16) and means for supplying a separating to the classifier (14, 16),a measuring device (18) for determining the maximum particle size and / or the particle size distribution of the material stream downstream of the separator (14, 16) is arranged, sifting device (10) a control method according to the - / regulating device (42) for controlling / regulating at least one of the release behavior of the separator (14, 16) as a function of the parameter influencing of the measuring device (18) determined particle size and / or the particle size distribution of the stream of.Furthermore, the invention relates to a method for operating a sifting device (10) for screening of a material with at least one static or dynamic classifier (14, 16) comprising the steps of: supplying a separating to the classifier (14, 16) and determining the maximum particle size and / or the particle size distribution of the material stream downstream of the separator (14, 16) and controlling / regulating at least one of the release behavior of the separator (14, 16) influencing parameter in a function of the determined particle size and / or particle size distribution.
