Optimise Your Abrasive Blasting - 3. How Air Pressure and Air Flow Affect Your Blast

[@andybulldog79]

My blast cabinet (pressure pot) blows air great however after the initial startup no/little media is shot out of the nossle resulting in an ineffective machine. Any advice?

Thank you for your comment. We need a little bit more information in order to help you with your question - what size and rating is your compressor, what pressure are you running the compressor at, which Elcometer ABM are you using, what is your grit valve setting, how long is the blast hose, and what size nozzle are you using? All of these answers will help us work out what the issue is. Please contact [e-mail] or visit www.elcometer.com/contact-us to find your local Elcometer distributor.

interesting concept, higher cfm larger nozzle operation. looking forward to part 4 in the series, surely more cfm means more fuel = more cost?

[@johnbasford2529]

of course if you guys have a solution to speed up blasting time at no extra cost thats ground breaking; the biggest bottle neck on any larger infrastructure project is the blaster not the painter, so if paint teams can get on jobs quicker asset return to service will be quicker. and if it saves money as the contractor i will be quids in!

Thank you for your comment. In part 4 we look at exactly that - if running a higher cfm compressor at a higher pressure increases your fuel costs enough to increase your overall project costs. We don't want to spoil it but the findings are very interesting!
