The 9 critical points to check you get the most out of your air blast machine and process

Here are 9 critical points to help you get the most out of air blasting:

1. Ensure You’re Working To The Correct Parameters.

2. Select The Correct Air Pressure To Deliver The Chosen Media And Optimize Both Work Speed And Costs.

3. Choose The Smallest Media That Will Do What Is Required.

4. Remember That A Small Heavy / Dense Media Particle Will Gain Much More Energy RSKI1000-SoThan A Large Light Particle.

5. Media Flow Regulation Requires To Be Optimised On A Pressure System.

6. On The Venturie / Suction Delivery System Alternative Regulation Requires Attention.

7. Surface Consistency And Repeatability.

8. Nozzle And Air Jet Size Compatibility On A Venturie Fed System.

9. Quality And Delivery Of Your Compressed Air.

Air Blasting Tip 9 – Quality And Delivery Of Your Compressed Air For Air Blast Systems

 

All dry blast systems require dry, oil free air delivered to the process. Small amounts of moisture and oil cause the media particulates to stick together and prevent the free flow of blast media.

Air Blasting Tip 8 – Nozzle And Air Jet Size Compatibility On A Venturie Fed Blast System

 

Check and make sure that the air jet and nozzle bore sizes are optimised.   It is a fact that when checked many venturie blast systems have air jets and nozzles that are entirely miss-matched.

Air Blasting Tip 6 – On The Venturie / Suction Delivery System Alternative Regulation Requires Attention

 

RSKI_1000Under the blast media hopper, placed under the base of the cabinet floor or under the cyclone unit, you will find the blast media pick up device, referred to in our introduction Part 1.  There are several designs on the market each purporting their advantages, however, in principle they almost always work the same, some designs better than others.   It is important to understand how this simple but effective pick up method works as this is critical to the process.

To draw both blast media and air in through this pick up device, it requires to be set up by adjusting the air to media ratio. Once fixed, this is set and need not be changed until another blast media or size is required.

Air Blasting Tip 4 – Remember That A Small Heavy / Dense Media Particles Will Gain Much More Energy Than A Large Light Particle

 

Heavier / dense blast media may need a pressure blast system consideration to enable sufficient media flow to be achieved.  As described in the pressure blast cabinets and systems introduction Part 2  heavier and denser medias may not be capable of being delivered by a venturie / suction system because it requires sufficient energy to bring the blast media up the delivery tube to the blast gun and the system becomes inadequate.

Air Blasting Tip 3 – Choose The Smallest Blast Media Size That Will Do What Is Required

                  

Smaller sized air blast medias will saturate the surface fastest.

Either venturie / suction or pressurised delivery systems are capable of delivering many more media particulates per second.

Air Blasting Tip 2 – Select The Correct Air Pressure To Deliver The Chosen Media And Optimise Both Work Speed And Costs

 

If glass beads are chosen as a beadblast process, they are initially round and have no cutting edges, they are relatively soft but still friable. If they break on impact, the two or more particles now have potential cutting edges.
