Using an ultrasonic separator to sieve and size copper/zinc alloy material for powder paints and coatings
It is common practice to screen fine metal powders when used within the coating industry to ensure an even coat is applied while also preventing blockages to equipment such as spray nozzles during application. A manufacturer of metallic pigments for paints and coatings was looking for a solution to check-screen copper/zinc alloy, also known as brass. The powder paint particles needed to be separated into a defined particle size to pass through the spray nozzle. Any oversize particles would cause blockages in the paint nozzle, resulting in production downtime and reducing productivity. Using a conventional copper powder separator, the mesh apertures would quickly block up resulting in reduced flow rates and loss of good product. As demonstrated in this video, using the high performance Finex Separator™ fitted with the Russell Vibrasonic® Deblinding System allows the manufacturer to screen brass consistently and effectively.
Production begins with the copper zinc alloy being ground in a ball mill before being transported into a cyclone. From the cyclone the product is fed via a rotary airlock into the Finex Separator™. Any oversize goes back to the mill where it is re-ground and fed through the process again. All the good product is dropped in the hopper or drum below the vibratory separator. It is important for the material to be of a particular size so that it can be fed through the paint nozzle and will not cause blockages. A uniform material size also ensures fewer irregularities when the spray is applied to the surface of another material.
