Abstract:
     The invention relates to a wet sand-blower used for treating the surface of working part. It uses a suspending medium in grinding fluid carrier, for example water, as well as water containing higher proportional antirusting agent in the form of dissolved ion substance like sodium nitrite. In operation of the machine, it is necessary to monitor the size of medium particle; in order to use continuously, the useless medium less than certain size of particle is removed before circulation of remained medium. Until the present time, the monitor has had audible-visible indicator, but these devices are not actual. Above these problem can be resolved by means of at least one nozzle used for making grinding fluid with medium and dissolved ion substance inject to workpiece, and the wet sand-blower which includes a device of transmitting grinding fluid to the nozzle and a additional device of measuring conductivity of grinding fluid.
