Apparatus for the classifying of powdered bulk materials

摘要: The invention relates to an apparatus for classifying powdered bulk materials, particularly ground clinker, limestone or cement raw material, by air sifting. material be classified is fed the cover plate of a cylindrical rotor and charged into sifting space having shape ring which extends between stationary vane spaced from surrounds rotor. While coarse descends in space, fine conveyed inside subsequent separating device air. In order simplify construction stocking, both housing surrounding it are assembled building-block fashion plurality identical sections, at least one tangential inlet connection being associated with each section. Each section can have cyclone its own fan. shaft also individual sections.
