Rotary Sifters for sale from Fresco Systems Australasia

Rotary Sifters

Rotary Sifters are suitable for both gravity and in-line operation. Product enters the sifter and is fed into the sifting zone by means of a screw auger.

In Stock

In the sifting zone the material passes along a cylindrical screen aided by 5 rotating single row brushes or beaters which sweep the material through the screen.

The material is separated into throughs and overs with the particle size separation depending on the aperture of the screen. Particles too large to pass through the screen, are called overs, pass along the screen until they are rejected into the overs container.

Particles passing through the screen are generally the desired product but the sifter can be changed if required, to reject fines from product.

Rotary sifters can be installed directly into the pneumatic conveying line or into any process system with a metered feed. Separation of products as fine as 0.25mm can be achieved with a Fresco rotary sifter.

As material is assisted by the brushes to pass through the screen, products, which are high in fat, or smear easily, are ideally suited to rotary sifting.
