Hi, I'm new here and looking for a solution to why are my ceramic sandblasting tips wearing out in less than a minute. It is a air pressure type sand blaster from Northern Hydralics rated for 60-110 # air pressure and 6-25 cfm. I tried it at 80 # and less. Using Black Beauty (recycled). Going to try new to see if that makes a difference. I have a vacuum type blaster as well with tips lasting for hours, thought the pressure type would be faster and more efficient.
