Abstract:
1. An apparatus for treating a particulate material, comprising an elongated, tunnel-like single process chamber having an inlet and an outlet, a material to be treated in said process chamber being moveable from said inlet to said outlet during a treatment, a bottom of said process chamber having overlapping horizontal guide plates forming slots there between extending in a longitudinal direction of said process chamber, said overlapping horizontal guide plates being superimposed in that a process air is introduced via said slots into said process chamber as two flows oriented transversely with respect to said longitudinal direction of said process chamber and said two flows being oriented oppositely toward each other, said two oppositely oriented flows impinging one another along a breaking-up zone, air guide elements arranged in said bottom, each of said air guide elements being pivotable in a generally horizontal plane about a generally vertical axis, and an adjustment device which pivots said air guide elements about the generally vertical axis about which each of said air guide elements is pivotable so as to adjust said air guide elements in such a way that a variable movement component in said longitudinal direction is superimposable on said process air for adjusting a longitudinal advance movement of said material passing said process chamber from said inlet to said outlet.
