Circular Vibratory Screeners
Circular Vibratory Screeners and Circular Vibratory Screener units on base PG
The Circular Vibratory Screeners are designed for sieving bulk materials according to particle size classes.
The operating principle of the Circular Vibratory Screeners is similar to the operating principle of the analyzer, except that supply of the material to be sieved and discharge of the separate classes from the surface of the sieve and tray are continuous.

Advantages of Circular Vibratory Screeners units:
- The distance traveled by the material particles during screening exceeds the diameter of the sieves installed, which improves sieving efficiency;
- Dust discharge is eliminated;
- The Circular Vibratory Screeners is equipped with corrugated discharge hoses and plastic receiving containers;
- Efficient screening using reciprocating helical vibrations of platform;
- Supply of elastic discharge hoses that do not distort the vibrations, for connecting pipes to receiving containers.
Advantages of GR units with PG:
- Uniform feed of material to upper sieve of Screener;
- The material feed rate is adjusted by:
- moving the slide gate in the feed hopper;
- changing the amplitude of the feed tray vibrations making it possible to change the thickness of the material layer in the tray.
- Sealed connection of feeder, sieving elements and receiving containers;
- Efficient screening using reciprocating helical vibrations of platform;
- Increased output of Circular Vibratory Screeners GR 40 and GR 50 through simultaneous loading of material into several identical sieves on one sieving column.
