Moisture: 

Clumped Media PicOne problem our micro-blasting customers run into, is that their system gets clogged and stops working properly. This can be due to excessive moisture in the system causing the blasting media to form clumps and obstruct media and air. Below is an example of clumping media in a tank.

This moisture can be introduced to the media if it is not being stored in an airtight container as the material will soak up the water in the air. Additionally, the facility’s air supply could have too much water vapor and would require a compressed air dryer to remove it from the system.

 

Mismatched Sizes:

The blockage can also occur due to the use of mismatched media, jar and tip sizes. If the media is larger than the tank and/or tip is specified for, then it can create an obstruction allowing only air to flow out of the handpiece. Use these charts to correctly match your components to your carbide or crystal tips.
