Why is the sandblaster surging and clogging?

Trying to figure out why your sandblaster is surging or clogging?

Well, I have some solutions for this in the sandblaster manual and some simple things to look at below.

People have been coming to me saying that while they were blasting the sand will start surging. First you will start out with a bunch of sand and the next minute- none at all. It can be really hard to work on a project and then this surging happening right in the middle of the job. What a pain!

Some people state that the system seems to be full of sand and gets clogged up even though the air is perfectly dry. Then they blow it back out and it works for a little bit longer.

Why is the sandblaster surging and clogging?

Here are some of the things to ask yourself:

1. Is the sandblasting media all the way dry?
2. Is the media a proper size for the blaster’s components such as the hose, pickup tube, and nozzle? Make sure its not too course because it could be jamming up the system.
3. Is the rubber pickup hose deteriorated inside? Abrasive could bind up on non smooth internal parts.
4. If you have a siphon sandblaster system, have you tried moving the pickup tube to various depths? A tube placed at different depths may work better.

If non of these help, you may want to consider picking up my sandblaster modification plans to fix abrasive flow problems. See, manufacturers aren’t always perfect and this can help solve that problem.

    well i’ve looked at your site a few times and you really don’t give a lot of info , basically a sales pitch for your book.

    If you are recycling your sand it brakes down or if your using sand that is’nt one grit that will cause it to clod and or surge. Hope that helps.

    In response to David Sullivan, I don’t have a problem with a ‘sales pitch’
    There is still a lot of very useful information
    I’m a motorcycle technician
    I’ll help just about anyone (as I already do on multiple forums) but, it has cost me too much in time, effort and actual cash to just give away everything I’ve learned or ‘invented’ in last 40+ yrs.

    Many blasters have a vibrator attached to the tank, generally near the bottom. This extra component is worth the investment, but most inexpensive units do not have this feature. The more media in the tank, the tighter the pack. Adding a vibrator can help significantly, but be careful of its placement. Keep it on the tank body and away from all fittings. Vibrations at the fitting connection point can cause equipment failure. A cost effective approach is the hand held massager. Some are even curved like your tank. Add this to Eric’s good advice and your downtime clearing clogs will be reduced.

    Great tips Ross! I talked about the vibrators in the ebook here: http://www.sandblasterinfo.com/sandblaster-manual/ and I just updated it which lists all the research about where to get them, along with the different types.
