Shot Blasting Tip 9 – Check Your Component Starting Condition Is The Same

 

Sometimes things change … including the starting condition of your component parts to be blasted. Worn tooling, changes in materials or investment in new manufacturing methods can result in you no longer getting the result from your shot blasting machine.

Shot Blast Tip 8 – Check Your Blast Wheel Amp Efficiency

 

A number of factors can affect blast wheel operating efficiently, some of which may not be obvious until your shot blast machine is stripped down and/or serviced. Monitoring the amps the blast wheels are pulling can allow you to see that something needs attention.

Shot Blast Tip 7 – Check Your Blast Pattern

 

Every time you use your shot blast machine, wear will take place on Blast Patternanything the abrasive comes into contact with. In the blast wheel itself, over a given period this will result in changes that will affect your blast pattern (how and where the abrasive is thrown).

Shot Blast Tip 6 – Regularly Check Your Wear Parts In Your Shot Blast Machine

Wear parts in your shot blast machine are the: blades/vanes, control cage, impellor and side / top wear plates in the blast wheel(s) themselves and the wear protection plates in the blast zone (in the area calculated to have the most impact from the abrasive when it is thrown from the wheel).

Shot Blast Tip 5 – Monitor Your Abrasive Removal Size In Your Shot Blast Machine

 

The blast media in your shot blast machine  is provided as a “working mix” to achieve your required process.  After a period of blast time it will not perform to the required standard as it has now reduced in size. If it remains in your machine, you can expect to increase the wear and degradation of the blast wheel components together with the recovery system of your machine.  It will increase production times and power consumption because of the longer blast duration required.  An efficient separator will remove unwanted contaminants and undersized media without carrying out good, usable abrasive. It is vital you regularly check the efficiency of your separator and the size at which media, fines and dust are being removed.

Shot Blast Tip 4 – Ensure Contaminants Are Removed From Your Shot Blast Machine

Just as abrasive circulates in your shot blast machine so will any contaminants that aren’t removed by screens (if fitted), by the air wash separator and/or dust collector.

When larger oversized particles are allowed to remain in the machine they can cause damage to the blast wheels (giving a high risk of blast wheel part breakage) and can affect the finish produced and process times adversely.

Shot Blast Tip 3 – Check That The Abrasive Condition Is Good In Your Shot Blast Machine

As abrasive is recycled and re-used within your shot blast machine it is affected by impact. It will gradually reduce  in size as a result of a combination of: splintering, spalling (peeling), deformation (i.e. rounding) or smoothing (i.e. grit becoming blunt).
