For 70 years the AZO cyclone screener has been used with great success for screening bulk materials in the food, plastics, pharmaceutical and chemical industry.
The product is metered into the AZO cyclone screener via the inlet pipe. This can be done by means of a rotary feeder or a metering screw. The feeding screw transfers the product into the screening chamber where it is gently swirled through the screen fabric by the fluidizing bars. The fines drop through while coarse particles such as contamination and agglomerates are carried on and discharged continuously. The baffle at the end of the screen prevents fines from entering the coarse product. The screen fabric, which is mounted on rings, can vibrate freely and therefore cleans itself automatically. It can also block blows softly and thus is largely insensitive to foreign matter. Sack fibres are eliminated too without forming a beard in the screen which might adversely affect the screening. Due to the carbon fabric of the screen, electrostatic charging, which occurs when screening e.g. PVC powder, is excluded. The screen can be exchanged easily and in a short time without using any tools. In addition, the rotor is very simple to remove. When the machine is not working, a large inspection door at the screener body makes it possible to check the complete surface of the screen basket easily by turning it 360°.
