Media Blasting is a pretty easy process when you simplify into the fundamentals. You blend an abrasive media with high pressure air and shoot it out of a little orifice in a gun/nozzle. Media blasting is very effective if you make sure you follow some relatively simple ideas.
Blasting Tips From A Pro - Successful Farming for Beginners
The top thing that will trigger a media blaster to work incorrectly is a compressor that can't stay up to date with the blaster. Be sure to examine the ratings of the blaster you are buying (or own) versus your compressor. Ideally you do not desire your compressor to be at max capacity when running the blaster.
Bear in mind that media blasting requires a high quantity of constant pressure to work efficiently and if your compressor can not produce the volume needed, the blaster will NOT work correctly. How to choose the right sandblaster.-The industry requirement for pressure at the nozzle is 80-100 PSI. Less than this and the media will not have the force needed to properly remove product.
While it's great to have a long airline that can reach throughout your store or driveway, it can dramatically injure the efficiency of your media blaster. Try to keep your pipe as short as possible and without any bends or kinks. Extreme lengths and bends can cause the compressor to work more difficult and reduce performance.
Every loop or difficult bend in the line will cause a significant drop in pressure (we have actually seen 5-10 PSI for each difficult bend or kink in the blaster pipe). We hinted at it above, however we can't stress enough how crucial it is to have an appropriate air separator or clothes dryer in line on your compressor.

They are low-cost insurance coverage to prevent those wet clumps of media obstructing up your pressure blaster. Most pressure blasters have similar deadman-style valves that block air or media. These valves do not constantly need to be opened fully. Each media/nozzle combination and job need different settings. A general guideline is that your air to media ratio must be 90/10.
We suggest doing a test run and gradually open the media valve up until simply after it begins removing material off of the test piece. One negative thing that often gets stated about media blasting is that it can warp thin panels and in fact damage parts by removing too much product.
You desire to have a constant side to side motion when blasting. DO NOT stop and blast in one focused location for any long duration of time as it can warp thinner panels and remove excessive material on some surface areas. Additionally, keep your nozzle at a 60-45 degree angle and aimed in the direction you are moving when blasting.
Follow these pointers and make your blasting tasks go as smooth as possible and do the task right. If you have any additional questions about blasting feel free to send us a message or dive onto our online forums and join our technical discussions! (different types of abrasive blasting).

When you've been in business of media blasting and painting for almost 30 years, you tend to pick up a few concepts and pointers that make life a little easier. For Jim Deardorff, who owns and operates Superior Coatings in Chillicothe, Missouri, those shortcuts can likewise suggest a little bit more cash in his pocket, because time actually is money in his company.
A few years earlier, he even media-blasted and repainted a fighter jet that is on fixed display screen at the Chillicothe airport. In the process of constantly looking for new responses, he's developed his own media mix and process, called Classic Blast (classicblast.com). It includes a low-pressure cleansing procedure that utilizes a distinct mix of fine, dense aluminum oxide, trace minerals, and graded walnut shells.
Preparation Is CrucialPower-wash the area you are media-blasting to remove surface contamination. Cleaning can decrease blasting time approximately 50% when grease and oil residue are present on the surface. Salt contamination (chlorides, sulfates, and nitrates) can be equally harmful. If salts are not gotten rid of prior to painting, loss of paint adhesion can happen.
The elimination of these products with blasting can use up to 10 times more effort than the elimination of paint. An easy method to inspect paint durability is to take a pocketknife and scrape across the paint. If you can scrape down to bare metal in one light pass, then the paint will most likely blast off easily.

To protect bolt threads, get some clear plastic tubing the very same inside size as the bolt, and then just move it over the bolt. For blasting loose nuts and bolts, locate a 24 or 14 and drill holes that match the size of the bolts. Place the bolts through the holes and connect the nuts on the other side.
