Reclaiming powder paint

Industrial screener with magnetic grate separator removes shot blast media and contamination from recovered powder coatings
Industrial powder coating systems have an average transfer efficiency of around 60 percent, meaning 40% of the powder does not adhere to the component being powder coated. However, this powder cannot simply be reused. Due to contamination collected during the spray process, the powder collected from the spray booth must be recovered and screened before it can be used again.
Contamination can include dirt, foreign fibers, grit or metal particulate from other upstream machinery. Any of these can affect the quality of the final coated product and, considering the industries where this process is widely used, such as aerospace, automotive and construction, quality cannot be compromised. Powder coating often follows an abrasive blasting process, such as shot blasting or sand blasting. Whilst this prepares the surface of the object for coating, small particles of the blasting media can be found in downstream equipment and reclaimed powder. These recovered powder coatings are screened before use.
In this demonstration video, the Russell Compact Sieve® with magnetic separator is used to screen reclaimed powder coating, removing oversize contamination including shot blast media. The vibratory sieve automatically screens the powder, effectively removing all contamination before reuse. The oversize contamination, such as the shot blast balls, is removed by the sieve mesh. Any ferrous particles fine enough to pass through the mesh are removed by the magnetic separator.
This Easy-Clean Magnetic Separator™ provides a convenient option to removing fine iron contamination from industrial powders. Rust, stainless steel shavings and worn particles from machinery can be easily removed by these integrated magnetic grids. All powder passes through the grid, with any ferrous contamination attracted to its rods, whilst good powder can flow past. The stainless steel magnetic grid is designed to provide optimum coverage of magnetic field strength, and its easy to clean design reduces maintenance time.
The Russell Compact Sieve® provides a high-capacity solution to check-screening reclaimed powder coatings, removing oversize contamination whilst fitting easily into existing production lines. This industrial sieving machine is available in a range of sizes and configurations, and a variety of upgrades are available for specific applications, such as the magnetic grid sieve for reclaiming powder coatings, and can be easily stripped down and cleaned without tools. Visit the Russell Finex website to find the ideal solution for reclaiming powder coatings.
