You have successfully done this? I've built two wet blasters using a dry pot and mixing nozzles with little success. The only success I've had is the mixing nozzle without a pot using the suction dry feed. Please elaborate on your setup.
OP. Are you trying to pressurize a wet slurry or drive the mix from the pot. Check that pot pressure before you blow yourself up. I tried a wet pot (should have tried glass) and also dry flow. I've increased the hose/valves to 1 inch and its still hit or miss with the pot. I used black bull and dry sand. I haven't tried glass yet but, I here that's what the pro guys use in a slurry. Let us know if ya have any success. Thanks
