What’s the use of hollow alumina balls in grinding wheels？‌Improve the density and grinding effect of the grinding wheel‌, ‌Heat dissipation and heat insulation effect‌, Optimize grinding wheel structure and performance, Enhance the strength and hardness of the grinding wheel‌, ‌Reduce production costs‌

Hollow alumina ball have a series of unique characteristics such as high purity, low density, high strength, high temperature resistance, low thermal conductivity, good corrosion resistance and easy processing. These characteristics make them widely used in thermal insulation fillers.
