How does Dry Ice Blasting work?
Dry ice blasting requires a dedicated dry ice blaster that stores dry ice, a sizable air compressor with an air dryer to provide clean & dry compressed air, blast & air hoses and nozzle(s). The amount of run time is determined by the size and capacity of the dry ice tank also known as a ‘hopper’.
Most systems use a rotary feed system to move the dry ice from the tank into the blast hose, which then pushes the ice up to the nozzle with pressurized air. Other dry ice systems increase their cleaning power by adding abrasives to the dry ice stream.
When the dry ice stream hits the unwanted material, it sublimates, creating an explosive freezing effect that loosens and removes surface particles.
