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.
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 … Continue reading
Every time you use your shot blast machine, wear will take place on anything 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 … Continue reading
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 … Continue reading
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 … Continue reading
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 … Continue reading
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).
