Why dry ice particle size matters?

In this edition of Cold Jet Academy, we are going to a look at the differences in dry ice particle sizes and why they matter.

Kinetic Energy: Softer surfaces require smaller particles, and therefore less impact, to avoid damage. Also, smaller particles are generally better for the removal of thin, hard contaminants while thick or brittle contaminations can be more easily removed with larger particle sizes.

Surface Finish: Tighter geometries can be cleaned more thoroughly with smaller particles by impacting the surface more times over the same area.

Air Flow: Smaller particles require less air to propel the dry ice to the cleaning surface. This provides better ergonomics and decreased noise levels.

How to create smaller dry ice particle sizes?

Cold Jet's product portfolio includes the following technologies for setting the appropriate particle size:

- Dry ice in-line fragmenters are used to create varying sizes of dry ice after it has been fed into the blast stream.

- Dry ice shaving technology is used at the feeder to produce sizes between 0.3-0.9 mm.

- Dry ice particle control system (PCS) is the latest and greatest technology to precisely cut particle pellets into 28 different sizes.

How to get savings from the right particle size? 

The correct size dry ice particle also has an optimal effect on cleaning times and the consumption of dry ice & compressed air. Would you like to know more? Please  contact us for other dry ice blasting recommendations for your application!
