1. The aeration trough consists of a top flume and a bottom flume, connected with flanges. The flumes are divided along their entire length with a porous partition. Unique characteristics: The trough has two arms inclined at the angle α to the horizontal plane, consisting of at least one segment. Each arm has a bottom flume (1) and a top flume (2). They are connected with articulate connections to the self-aligning bed (4), resting on a bearing support (5). The trough arms are designed for simultaneous transport to the left and to the right. A change in the transport direction of pulverised material is realized by switching the stepper drive (6), which results in the change of the switching angle by 2 α.
