I wanted you to know the option of screening the media outside of the machine. If not by an outside company, you may consider investing in a stand-alone screen separator for yourself. Some companies with multiple peening machines do this to avoid putting one on every machine.

Best of luck. Let me know if you need training in Viet Nam. It would be nice to visit there again.
