Abstract
A wet blasting machine having a slurry reclaiming tank and a clear liquid tank, both located at the lower part of the blasting chamber. An abrasive particle reservoir is located adjacent the blasting chamber and above the reclaiming tank. The inside of the reservoir is separated by a perforated plate into an abrasive particle chamber and a liquid chamber. The lower part of the separating plate defines an outlet for the abrasive particles. A blasting gun is positioned inside the blasting chamber, and a high pressure pump supplies clear liquid to the gun. A slurry-inducing pipe passes through the outlet of the abrasive particle chamber and has one end thereof opening into the liquid chamber, and the other end thereof connected to the blasting gun. A slurry pump supplies the mixture in the reclaiming tank to a liquid-solid separating device wherein the separated liquid is sent to the clear liquid tank and the separated particles are sent to the abrasive particle chamber.
