Figure: Shown blast nozzle sample
Jet injection type of nozzle is a very powerful blasting method. Nozzle design is very particular to the usage of abrasive material and the requirement of compressed air. Nozzle design might be similar to pump system. As nozzle design is to create a low pressure zone that to suck abrasive material to mix together with compressed air into a mixing zone and go through expanded zone to create a tremendous pressure or the mixture been compress and blast out through nozzle.
