Can someone guide me on how to get the sand blasting cabinet blasting sand again? there were instructions on the sheet to not change or add media to it so i left it alone, but i do need to use it at some point soon, so help would be appreciated.
Tried to use the sand blasting cabinet this morning real quick to clean something up. i was able to get it up and running easily enough. however, there was no aggregate coming out of the gun. i shut it all down and looked into the vortex generator and it was full to the door of blasting media. i would imagine it just wasnt pulling enough section to pull blasting media into hte gun, but i’m not sure.
hopefully this is the right space to put this post in.
Someone added large sand granules and a course black diamond abrasive. I think the media is getting clogged. The mixing valve is now missing a mixing screw. Also the moisture ridden air is probably causing some clumping.
I will get a screen to sift the abrasive sometime this weekend. I will also look for a new mixing screw.
The new mixing valve has been made. At some point this week the bell will get welded in and it will be functional again. The new gun has too large of an orifice. It is draining the air compressor faster than our poor anemic compressor can handle. I’m going to look for a smaller orifice consumable. Also with a good mixing vavle we can turn down the psi to 40 or 50 psi thus extending the range of the air compressor.
The new bell has been welded in place and mixing valve installed. I also sifted the abrasive. There was a lot of garbage in the abrasive. I also reinstalled the triggerless gun. There is a smaller orifice nozzle coming in the mail this week. The new nozzle will help. I have also turned the air regulator down to 40 psi. I was able to blast continuously without having to wait for air compressor to recharge. Also the left glove has been replaced.
The old switch had become unreliable. The switch should give us reliable service for a long time.
The cabinet got a tune up. The air pressure has been dialed to 50 psi and the mixing valve set. It was torture tested today on many parts that needed cleaning. It now reliably shoots abrasive and the compressor can keep up.
