Recycling screener VB15

circular vibratingfor bulk materials

This "Three-Stage Kascade" Internal Recycle VIBROSCREEN® separator offers 120 to 160 percent higher scalping or dedusting capacity than conventional screeners of equivalent diameter. It contains three screens of equal mesh; a bottom screening deck configured with a conventional discharge spout at its periphery, and two upper screening decks configured with 360° annular gaps at their periphery. Maximum capacity is achieved by feeding the top deck with significantly more material than it can screen efficiently, with three results: 1. A portion of on-size material passes through the screen to a central discharge chute, while the balance of fine material plus all oversize material cascades over the screen's periphery onto a "feed tray" that directs it to center of a second screening deck. 2. In the same manner, a portion of fine material passes through the second screen into the central discharge chute, while the balance of fine material plus all oversize material cascades over that screen's periphery and passes through a feed tray onto the center of a third screen. 3. The remaining fine material passes through the bottom screen to a common discharge outlet, while all oversize material is ejected through a common discharge spout at the lower screen's periphery. Kascade Internal Recycle Series screeners are specified as new for applications where space is restricted since diameters are significantly smaller than those of conventional screeners having equivalent capacity, or as on-site retrofit kits to increase the capacity and efficiency (minimized "carry-over" and ejection of on-size material) of existing screeners at substantially lower cost than purchasing new equipment.
