Abstract:
A milling installation for the generation of meal-fine products, with a comminuting device, a sifter supplied with sifter air for the separating-off of fine material generated in the comminution device from still-present coarse material, and with a fine material separating device for separating-off the fine material from the sifting air of the sifter, wherein the sifter used in the milling installation is a static cascade sifter designated as a V-sifter with-two sifting zone boundary walls enclosed by a shaft-form sifter housing and forming between them a sifting zone through which the sifting air flows in transverse flow, which walls have guide plates arranged in cascade manner aligned downward in a direction to a discharge opening for sifted-out coarse material, in which the two guide plate walls and therewith the interlying sifting zone are arranged obliquely at an angle deviating from vertical, and the V-sifter with a lateral discharge opening for the sifting air laden with the sifted-out fine material is connected with a lateral input opening of the fine material separating device, in such manner that there is no interposition of a transport device or pipeline, so that V-sifter and fine material separating device form a compact structural unit.
