Different Types of Ribbon Flighting for Screw Conveyors
Post type ribbon flights use round bar posts that are typically located every 90 to 120-degrees around the diameter of the pipe. Ribbon flighting is then welded to the posts to complete the screw. Integral leg ribbon screws are more cost effective to manufacture when compared to post type ribbon screws.

Rake Classifier
rake classifier mechanism. The rake classifier (Figure 9.18(a)) uses rakes actuated by an eccentric motion, which causes them to dip into the settled material and to move it up the incline for a short distance.The rakes are then withdrawn, and return to the starting-point, where the cycle is repeated. The settled material is thus slowly moved up the incline to the …
