I am no longer in the shot peening business, but I am still involved with sifting products through screen separators - both rotary- and deck-style sifting. We have recently had a request from a customer for an alarm when a screen has been compromised. We are not aware of any detection system for compromised screens other than periodic inspection. But, I though I would try this forum to see if the peening industry has developed anything that we could apply.
I would welcome any thoughts you may have.
