本文介绍了一种新的选矿工艺，即湿法喷砂法。在这个过程中，用0.2-0.4MPa的压缩空气，而不是低压，从喷枪中喷射出含有液体的低浓度磨粒泥浆，这可以称为温和湿式喷砂过程。采用这种修整方法，可大大提高超硬磨料砂轮的磨削性能。

THIS PAPER IS RELATED TO THE NEW DRESSING PROCESS WHICH APPLIES THE WET BLASTING PROCESS. IN THE PROCESS, LOW CONCENTRATION SLURRY OF ABRASIVE PARTICLES WITH LIQUID IS BLASTED FROM THE BLASTING GUN BY MEANS OF COMPRESSED AIR OF RATHER THAN LOW PRESSURE, 0.2-0.4 MPA, WHICH MAY BE CALLED GENTLE WET BLASTING PROCESS. BY ADOPTING THIS DRESSING METHOD, THE GRINDING PERFORMANCE OF THE SUPERABRASIVE WHEEL IS GREATLY IMPROVED.
