In the wet blast process the blasting medium is in water. The compressed air and the blasting medium-water mixture are fed to the blasting gun via two separate tubes. Because each individual granule of the blasting medium is surrounded with a water film this process is often used for finishing. In addition wet blast cabinets are also regularly used for oily parts because this often leads to problems in a dry cabinet. For uniform blasting the medium-water mixture is continuous stirred in the sump. Only mineral blasting media are used as a rule. The wet blast process is available as manual operated blast cabinets but also as a fully automated process.
