Re: Steel grit/Stainless Grit

I've been using steel grit for about 2 years in a pressure cabinet with vacuum reclaim. Life of the media is many times that of AO because it does not fracture on impact. Any dust comes from the material you are blasting and not the steel grit. You can blast at higher nozzle pressure and get more do...

Re: Opinions on this

My first question, and one you need to have an answer to before going into any business venture is: Who is your target market? Why will this service be in demand? First impression on this is the market would be pretty small, but more power to you if you can get the work. From a practical standpoint ...

Re: Anyone ever turn a portable garage into a blast room?

The size and roll up door would be great and it would be pretty quick and easy. The major downside to the ones pictured would be the wood floor, if I had a blast room that size I would want to be able to drive a forklift inside it.

Re: Black stuff while blasting...

Is this a new or used screw compressor? If used has the separator element been changed? They need maintenance.
Use an air gun on the same line as the pot and blow it on a white rag and/or a piece of glass and see what comes out.

Re: Which compressor!

I purchased the 10hp 120 gallon compressor from Eaton. I understand the SCFM @100psi is 38. My question is this. I do not blast at 100 psi. I chemical strip now, and etch the wheel out with glass bead around 45-60 psi. I would like to achieve the highest CFM at that running psi. Is it lowered or hi...

Re: Which compressor!

What do you have for power? If single phase then 10 hp is about the max. You could run more than one pump on single if you have the amps available. If you have 3 ph that changes everything. My input would be to figure out the max size compressor you can afford, then get one about 4 times that size i...

Re: Anyone using a rotary screw compressor?

I have a SULLIVAN-PALATEK 40 hp rotary screw. The ones that are in an insulated enclosure are nice and quiet. Mine is open and very loud. They are designed to run 100% duty cycle. Maintanence is not cheap, mainly for the seperator filter and special oil but it only needs changed every 4,000 run hour...

Re: light pitting , what can be done

If the customer will go for it hammers or heavy texture powders will hide a lot. I give them that option for one price or add $$ for extra coats and sanding.

Re: Steel Grit for blast cabinet.

Only other thing I'd like to add is that your consumables, you will go through things at a much higher rate, so there is a down side ... Small but still It's definitely harder on gloves and glass. My supplier actually tells me nozzles will last longer with steel than AO since it isn't as sharp. I'm...

My blast pot attached to my cabinet only holds a 50 lbs so dont think i need more.
If your pot holds 50 lbs of AO or slag it will take close to 125 in steel grit to fill it. A 50 lb bag is tiny.
