How to choose garnet particle size during sandblasting
Sandblasting mainly uses high-speed rotating garnet particles to hit the workpiece to remove impurities on the surface. The greater the impact force, the faster the blasting target can be reached. In use, smaller garnet particles are usually selected to enhance this effect. For many users, it is suspected that such a small garnet sandblasting abrasive will produce a much smaller effect than quartz sand. Although the particles of quartz sand are relatively large, it is weaker than garnet sandblasting abrasive in terms of hardness and machinability. In sandblasting, the smaller the particles, the more advantageous. At the same time, more particles can be used to hit the impurities in the coating to achieve a faster sandblasting effect.
