AZO cyclone screening with ultrasonic assistance

AZO cyclone screeners combine operationally safe technology with high performance and easy maintenance and cleaning. The screeners can easily be integrated into existing systems thanks to their compact design.

Recovery of coating powders – cutting costs with maximum use of products

Like many other branches, the coating powder industry is also under growing financial pressure and yet at the same time it has to meet the most stringent quality standards. Efficient recovery of powder crucially improves process stability and operating efficiency. In order to avoid a drop in quality, it is necessary to use systems that eliminate foreign matter and agglomerates reliably.

In combined operation with tried-and-tested vacuum conveying systems, AZO’s cyclone screeners have demonstrated outstanding results in recovering coating powder. These systems are also eminently suited for recycling powder overspray.

AZO cyclone screening with ultrasonic assistance

Sonic pulsing of the screen mesh can be used or fitted retroactively in the AZO type E, DA, FA and RA cyclone screeners.

Key advantages:

• Increase in screening capacity
• Improvement in selectivity
• Longer times between cleaning
• Straightforward retrofitting in existing machines
• Converter is outside the screener and hence outside the flow of powder.

The use of ultrasound causes the stainless steel screen to vibrate at high frequency. These minute vibrations prevent near-size particles from sticking in the mesh of the screen fabric. The screen mesh stays clear for longer, which in turn noticeably improves selectivity. This may result in an increase in screen capacity. The screen basket needs to be removed for cleaning far less often and this significantly increases the useful life of the machine.
