Powder coatings and Russell Finex
From the infancy of powder coatings in the late 1960's/ early 70's, Russell Finex have been there to help solve sieving and separation problems. As the powder coatings industry has developed and become more complex, we have been there to deal with the challenges of increases in size and capacity caused by micronising mills. We have also solved mesh blinding problems faced by so many powder coating manufacturers.
In a nutshell, we understand powder coatings and their unique properties.
Eliminating mesh blinding
The biggest single sieving problem created in powder production is mesh blinding. This occurs when the agglomeration of powder particles combine to block the mesh apertures due to static adhesion. Conventional de-blinding devices such as rubber balls, plastic sliders and discs can damage the mesh and are not always effective.
The Russell Vibrasonic® Deblinding System uses ultrasonic frequency to ensure mesh wires are friction-free and, as a result, eliminates mesh blinding completely. This allows you to sieve consistently to accurate specifications, increase your capacity and to sieve on finer meshes.
In response to demand by major users of powder coatings the Russell Vibrasonic® Deblinding system is now certified to the following EU and US standards:
Europe:
ATEX certified for use in zones 20, 21, 22, 0, 1 and 2 (Group II, category 1, gases and dusts and explosion protection is to E Ex d m IIC T4).
Rest of the world:
US electrical standard NEMA 9 (Class I, Div I, group C & D, Class II, Div I, groups E, F & G). FM (Factory Mutual) and CSA are also recognised approvals.
Combining the Russell Compact Sieve and Vibrasonic® Deblinding System provides the ultimate sieving unit delivery outstanding performance to match today's modern milling techniques.

Powder recovery
One of the major advantages of powder coatings over conventional wet paint is the ability to recover overspray powder. However, this powder needs to be check-screened before re-use to ensure it is free of any contaminants which could affect final product quality. The range of Russell Compact Sieves is the ideal solution for check-screening recovered powder.
As an added benefit, the Compact Sieve responds to the demand for neater, more efficient installations as it solves the problem of confined space and creates a 'straight through' installation.
If very high quality powders need to be recovered for critical applications such as the automotive industry, then they will need to be sieved at low micron sizes. In these cases, mesh blinding is likely to cause problems and the Russell Vibrasonic® Deblinding System will be required.

Highly pigmented powders
Due to modern today milling techniques used for the production of highly pigmented powders, it is necessary to use the correct sieving system to ensure both product quality and production efficiency are maintained. Russell Finex uses its vast experience combining high speeds (2800 rpm) with Vibrasonic® technology to offer solutions commonly found in many powder coating manufacturers across the world.
