High roundness and low wear ceramic beads

一,Ceramic Beads Abrasives as a key medium in the field of industrial grinding, due to their unique material characteristics and structural advantages, present significant advantages in various types of grinding scenarios,

The main advantage of the ground ceramic balls lies in the excellent abrasion resistance resulting from the high hardness characteristics of their main building materials such as alumina, zirconia, silicon carbide, etc.:
  1. Alumina ceramic beads (Al2 o3 content greater than 90%) Mohs hardness up to 8 - 8.5, much more than ordinary metal beads (such as steel beads, Mohs hardness 4 - 5) and glass beads (Mohs hardness 5.5 - 6), the wear rate in long-term grinding is extremely low;
  2. zirconia ceramic beads (zro₂ content of more than 95%) have not only high hardness (Mohs hardness 8.5), but also a certain toughness, which can reduce the fragmentation due to impact and extend the service life;
 3. silicon carbide ceramic beads (Mohs hardness 9.5) are closer to diamond hardness and suitable for grinding high hardness materials (such as ore, silicon carbide powder), the abrasion resistance is more than 10 times higher than steel beads.

二,Features of ceramic beads : 
1.Strong chemical stability, no contamination by impurities 
2.The grinding efficiency is high and the refining effect is good 
3. high density, high hardness  of Abrasive ceramic beads, so that they can quickly break the material by high frequency impact and shear action, improving the grinding efficiency:

三,The advantages of ceramic beads：
1. the density of zirconia ceramic beads is about 6.0 G / cm³, much higher than glass beads (2.5 G / cm³) and plastic beads (1.2 - 1.5 g / cm³), at the same rotational speed, its gravitational potential energy is larger, the impact force on the material is stronger, can quickly break the agglomeration of particles;
2.high circularity of ceramic beads (circularity of most products > 95%) ensures smooth movement in the crushing equipment (e.g. sand crusher, ball crusher), reduces inefficient friction with the internal wall of the equipment, converts more energy into crushing work on the material;
3.small size ceramic beads (such as zirconia microbeads from 0.1 to 1mm) can provide a larger specific surface, more complete contact with the material, suitable for fine grinding (e.g., nanoscale mud preparation), can fine-tune the particle size of the material below 1μm.

六,Ceramic Beads Abrasives can be adapted to many grinding needs and equipment depending on the type of material, particle size, density:
1. from rough grinding (such as ore grinding, choose alumina beads from 5 to 20mm) to finish grinding (such as ink color adjustment, choose zirconia beads from 0.5 to 2mm), covering different particle size requirements;
2. adapts to many equipment such as horizontal sand mill, vertical ball mill, stirring mill, airflow mill, etc., and is highly compatible with material morphology (liquid, paste, powder);
3. high temperature resistant (for example, silicon nitride balls can operate at 1200 ℃), low temperature resistant, suitable for extreme working conditions (for example, high temperature ceramic billet grinding, low temperature pharmaceutical materials grinding).
