Sponge Jet: 

Recyclers use rapid vibrations to shake and tumble reusable Sponge Media in a spiral path over a series of screens; each size-selected to achieve the desired result. The first coarse screen separates and ejects unwanted, over-sized contaminants (into a waste bucket) that may have been recovered with the blasted Sponge Media. The second screen separates (into another waste bucket):

• Fine dust
• Hazardous contaminants (e.g. lead, PCB, asbestos, radioactive particles)
• Stripped/broken-down coatings
• Fractured abrasives

Recycled media (typically >95% ) is funneled into a third bucket and ready for reuse – and when merged with a small amount of new media, it creates a consistent “working mix”. The screen opening size of the lower screen and ratio of new media can be adjusted to optimize the balance between acceptable dust levels and maximum media life. Recycle, Reuse, Reduce!
