VIBROSCREEN® PRINCIPLE OF OPERATION
The main screening assembly of a Kason screener is suspended on rugged springs that allow it to vibrate freely while minimizing power consumption and preventing vibration transmission to the floor. The assembly is equipped with one imbalanced-weight gyratory motor that creates multi-plane inertial vibration for the purpose of controlling the flow path of material on screen surfaces, and maximizing the rate at which material passes through the screen.

Material is fed onto the center of the screen, causing particles larger than

 screen apertures to travel across the screen surface in controlled pathways, and exit through a discharge spout located at the screen's periphery, while particles smaller than screen apertures pass through the screen onto a lower screen or exit through a lower discharge spout.

Single-deck screeners are generally utilized for "scalping" or "sifting"
(removing a small percentage of oversize material through the upper discharge spout), for "de-dusting"
(removing a small percentage of undersize material through the lower

 discharge spout), or for "dewatering"
(removing liquid through the lower discharge spout).

Multi-deck screeners (two-deck shown) are generally utilized for "classifying" of particles in three to five predetermined sizes, or when equipped with integral KASCADETM screening decks, for increasing the capacity of a screener without increasing its diameter.

Adjustable Flow Patterns
Flow patterns of material can be fine tuned for screening efficiency by repositioning the bottom eccentric weight relative to the top eccentric weight.

0° (In Phase)
From a central
feed, material
flows to screen
periphery in a
straight line.

30° Out of Phase
Material spirals slightly from the center to periphery, increasing retention time. Recommended for general purpose screening.

45° Out of Phase
Material flows from center in a distinct spiral pattern, further increasing retention time. Recommended for classification of particles and screening of wet material.

90° Out of Phase
Prevents oversize
material from
discharging.
