Apparatus for Classifying Charge Material

摘要

The invention relates to an apparatus for classifying charge material, comprising a static classifier which has a ventilating base oriented obliquely to the vertical and traversed by classifying gas; an inlet opening for charging the charge material to the ventilating base; an outlet opening for the coarse material; a downstream dynamic classifier which comprises at least one rotor; and at least one outlet opening for the classifying gas laden with fine material. The ventilating base has a ratio of width to vertical height of at least 0.45, preferably of at least 0.6.
