Screen separators are used to remove foreign or other unwanted material from product flows. They can classify dry bulk solids ranging from chunks to fine powders. Screen separators are used to separate solids and liquids in a variety of applications. Eriez provides a broad range of screeners for both wet and dry product separation. This book, "How to Choose and Use Vibratory Screen Separators" as written, is intended to help users select the correct vibratory screener for their particular process.

Circular Vibratory Screeners
Circular screeners feature a gyratory motion to move wet or dry product down and through a series of "decks", each with its own screen and with its own discharge spout. Depending on the end product, one, two, three or even four decks can be used to attain the desired degree of fineness. Generally, the gyratory motion is gentler and is ideal for more fragile product. A variety of mesh screens are available for each deck and to meet your specific need, decks are available in six sizes. Circular screeners are used for processing slurries, waste water, minerals, chemicals and other dry or dewatering applications. These popular screeners separate and size materials ranging in size from 1/4 inch (6mm) to 40 mesh.

Rectangular Vibratory Screeners
Rectangular vibratory screeners are available in a wide variety of sizes and shapes. Recommended screens range from 20 mesh up to 1/2 inch (12mm) size used for scalping. Rectangular vibratory screeners have a totally enclosed patented magnetic drive and can screen practically any bulk material from micro size to bulky chunks.

Mechanical Screeners
These screeners are relatively simple, rugged vibratory machines designed to handle a variety of bulk material. The screener is a tuned two-mass vibrating system excited by a motor driven eccentric weighted shaft. Corrosion resistant rubber springs transmit the exciting force and can "fine tune" the motion of the trough optimizing the flow rate for a specific application. Mechanical screeners are available in a wide variety of sizes, shapes and deck types.
