Default Sanblasting pressure pot. I always have trouble. Can someone help?

Hello

I have this cheapish pressure pot on wheels for blasting.

My problem: It blasts for a bit (like a few seconds) but then it is just air until I shake the pot. This repeats all the time. I am mostly blasting with one had while shaking the pot with the other hand to keep it going. Not ideal and it is getting on my nerves.


I use washed riversand from Bunning hardware.
I let this dry for about a year in the sun and when adding it to the pot, I run it through a mosquito metal grit.
The sand is bone dry and pours real well

I run 6 - 8 bar air pressure on the pot.

The pot has a valve at the bottom and I adjust this but then I suddenly get way too much stuff coming throuigh and then nothing again.

I only ever add a few handfulls of grit to the pot.
The nozzle is not getting clogged.

The compressor has a moisture trap AND the pot also has a moisture trap.

What am I going wrong?

Best Regards
Bernt
