The present invention relates to a sandblasting system which is preferably used in dentistry and which performs blasting with pressurized water, wherein the sand present in the sand pool is separated from water such that only sand will be withdrawn from said sand pool to the sand inlet. The sandblasting system according to the invention comprises an electric motor (1) driving the water jet pump (2)； a water jet pump (2) which, driven by the electric motor (1), receives water from the water inlet (3) and transfers the water to the hydraulic blast nozzle (6) in a pressurized manner by means of the water outlet (4)； a hydraulic blast nozzle (6) which vacuums the abrasive material in the sand pool (10) through the sand inlet (8) disposed thereon with the low pressure formed in the space within the body thereof while it outputs the pressurized water that it receives from the water jet pump (2) by means of the pressurized water hose (5) through the water outlet nozzle (7), mixes it with water and then ejects to the pieces to be sandblasted by means of the sandblast hose (9)； a sand pool (10) containing the sand to be used and to which the sand and water used in the system is redelivered； an air hose (11) which is located adjacent to the sandblast hose (9) or such that its outlet portion will correspond to the outlet portion of the sandblast hose (9) and which removes the water in the sandblast hose (9) outlet by blowing air into the sand pool (10)； and an air pump (12) which blows air into the air hose (11).La présente invention concerne un système de sablage qui est utilisé, de préférence, en dentisterie, et qui assure la projection d'eau sous pression, le sable contenu dans le bac de sable est séparé de l'eau de manière telle que seul le sable sera prélevé de ce bac de sable et amené à l'entrée de sable. Le système de sablage selon l'invention comprend un moteur électrique (1) entraînant la pompe à eau (2) ； une pompe à eau (2) qui, entraînée par le moteur électrique (1
