Ultrasonic device deblinds screener
To prevent screen blinding problems in a metal powder
screening operation, an R&D lab installs a single-deck round screener with an ultrasonic deblinding assembly.
Crucible Research, Pittsburgh, was experiencing problems
screening a metal powder with a single-deck round screener. Screen blinding slowed the screener’s
throughput rate and caused onsize particles to discharge with the oversize particles. When this occurred, an
operator had to stop the screening operation and manually deblind the screen, then rescreen the oversize particles several times to recover the onsize particles. These tasks required extra labor and time, which increased the screening operation’s costs. The lab wanted to find a way to eliminate this inefficiency.
