When it is working, the ball won’t pollute the grinding materials, so it can keep the purity and improve the stability of grinded materials especially the ceramic glaze. High density The high density, high hardness and the high grinding characters save the grinding time, enlarge the smashing room. So it can improve the grinding efficiency.
