1) Excellent wear resistance
2) High gravity,no pollution
3) Preferable toughness
4) Good stability
Characteristic:
1. The internal structure of the bead is very fine and homogeneous due to the special technique, thus ensuring the even quality of material being grinded.
2. Tough bead bears impact better, and minimum friction allows minimum wear down to the equipment.
3. High density greatly enhances grinding effect and efficiency.
4. Lower wear loss and enhanced service life.
