Circular Vibratory Screeners and Separators
sift, classify, scalp, or dewater bulk solids and slurries

Kason Vibroscreen® circular vibratory screeners (also called separators and sieves) separate bulk solid materials from solids and slurries using multi-plane, inertial vibration that causes particles to pass through apertures in the screen or to travel across the screen surface in controlled pathways.

Typical applications include sifting, scalping, classifying, de-dusting and de-lumping of dry bulk solids, or dewatering of solids-laden slurries. The screeners range in diameter from 18 in. to 100 in. (460 mm to 2540 mm) and are offered with single or multiple screening decks, separating particles in one to five predetermined sizes ranging from 2 in. (50 mm) to 500 mesh (25 microns).

A wide range of models and specialized options satisfy a broad range of applications from the most simple to the most challenging, in capacities ranging from several pounds/kilograms to more than 70 metric tons per hour.

All Kason circular vibratory screeners are offered in gravity-fed and in-line pneumatic models for batch or

The screeners are offered in two configurations, distinguished by the number and location of imbalanced-weight gyratory motors employed to impart vibration:

1. One imbalanced-weight gyratory motor mounted directly beneath the screening chamber

2. One or two imbalanced-weight gyratory motors mounted externally on opposites sides of the screening chamber

Standard Vibroscreen models

Stationary and mobile units are available in diameters from 18 in. to 100 in. (460 mm to 2540 mm) with single or multiple screening decks, yielding up to five precise particle classifications. The single gyratory motor of Standard Vibroscreen models is available with "E-Z Slide" imbalanced weights, allowing rapid, tool-free adjustment of multi-plane, inertial vibration for maximum screening efficiency.

FLO-THRU Vibroscreen models

This Kason innovation minimizes height requirements, and enables the bottom outlet to be positioned directly below the top inlet, allowing material to fall vertically through the screen at high rates. The external location of gyratory motors also makes Flo-Thru models suitable for high temperature applications. Stationary and mobile units are available in diameters from 18 in. to 84 in. (460 mm to 2135 mm).
