There are high crush strength which it could not be broken used for long time in the quick speed mill. Zirconia silicate bead formed by sintering. It is widely instead the fused zirconia silicate with pore and easy broken. Applications: Paint& Coating Ultra-fine grinding for cosmetic&Magnetic band Superfine grinding mineral(GCC,Kaolin and so on) Machine: Sand mill. Attrition mill
