The manufacture of powders or granules often includes a sieving stage to make a granulometric cut, or as a safety measure to eliminate undesirable particles.
Food, chemicals, minerals... Gericke centrifugal sifters have been used in all industrial sectors for over 70 years.
They are mostly gravity-fed by upstream equipment such as screws, feeders, sluices, vibrating tubes, etc.
Gericke also offers a range of centrifugal sifters that can be inserted into a pneumatic conveying line in dilute-phase pressure or vacuum. This less common configuration offers several advantages. In particular, the sieve shaker can be placed anywhere on the pneumatic conveying line, making it easy to install.
What's more, there's no need for a screen feeder. A further advantage is the automatic removal of rejects from the screening chamber.
The system is compact even for throughputs of several tens of tons per hour, and a single in-line screener can be sufficient to screen different products from different starting points.
Gericke's screening machines are available in a wide range of designs to meet the needs and requirements of industrial users.
The Group's test stations are equipped with an in-line sieve shaker on a dilute-phase pneumatic conveying line.
