External KASCADE' High Capacity Screener

By discharging oversize particles 360¡ around the periphery of a circular screening deck, the screener increases capacity improves efficiency, minimizes screen blinding, and prolongs screen life.

As material is fed onto the center of the screening deck, on-size particles pass through the screen and funnel through a lower discharge chute. Oversize particles flow outward in a spiral pattern, and cascade at any point over the periphery of the circular screen onto a spiral vibratory trough that directs the material into a high capacity discharge spout.

Allowing oversize particles to cascade 360¡ around the screen's periphery, instead of through a 15¡ to 25¡ opening created by a conventional discharge spout, eliminates a discharge capacity restriction associated with overs building up around the screen circumference.

The special screening deck is offered on any of the Kason's Vibroscreen® separators ranging from 40 to 72 in. (1016 to 1829 mm) in diameter and is available as a retrofit kit for any make of circular vibratory screener.

A range of accessories is available including clean-in-place spray heads, anti-blinding devices, articulated lids for rapid screen changes, and an automatic long-term lubrication system for gyratory motor bearings.
