SCREENERS Visual Encyclopedia of Chemical Engineering
Vibrating screeners, which operate at 18003600 vibrations per minute, are much less likely to blind than gyrating screeners. The deck is usually inclined at an angle of 3045°, although horizontal operation is also possible. Vibrating screeners have a greater capacity than gyrating ones, especially when separating fine material.
