1. Cutting efficiency  
Sea garnet, single crystal, round, sand pure, cutting stability, round single crystal structure to ensure the smooth cutting surface, the burst rate is low in the process of cutting glass.

• Whether blocked the sand pipe

The reasons for sand plugging pipe may be that there is excessive coarse sand with large particles, sand moisture, dust and fiber impurities.  
Sea garnet is clean and fine.  Rock garnet is formed by crushed rock and contains rock particles.
3. the Loss of equipment.  
Sea garnet, single crystal, round, less impurity, cutting smooth, low loss to equipment, especially nozzles and sand tubes.  
Rock garnet has sharp edges and corners, and it is easy to wear equipment (especially the inner diameter of the sand pipe) when passing through the sand pipe quickly.  Contains more impurities, easy to sand blocking, sand blocking and sharp edges corners increase the loss of equipment, increasing the maintenance and replacement costs.
