Sieve Metal Powders to 6 micron

Screening ultra-fine powders

The screening of metal powders with a particle size under 50 µm has always been a major challenge in the creation of new alloys. When undertaking product development metal powder producers have had to constantly make a sacrifice in throughput or separation efficiency. Ultrasonic technology has provided a little relief in the zone of 50 – 30 µm, but for ultra-fine metal powders below 30 µm, especially when the particle is an irregular shape or is prone to electrostatic interference, there has been no cost effective screening solution.

However, with Virto''s ScreenX vibrating sieves this is not the case. ScreenX achieves far greater capacities for fine and difficult materials in comparison to traditional sieving methods due to its multi-frequency technology that accelerates the mesh by up to 500G - which is a c. 10,000% increase in mesh acceleration compared to standard sieves. In fact, the finer the m...
