CGB is abbrevation of Ceramic Grinding Balls. It is made of high purity alumina.The alumina based products feature high temperature tolerance, hard wear resistance and high performance in ant-erosion . CGB is traditionally used in ceramic industry for body biscuit granule grinding and glaze process. according to the purity, it consists of 30%,50%,68%,75%,85%,90%,92%,95% and 99%.CBG CB also serve in petrochemical industry as catalyst bed, to help protect those catalysts thanks to their premlmum performance in high temperature tolerance and ant-erosion property. 


Various Classification :Cobr,shaping and diameter 


+Color Difference

  • Purity difference cause color difference .
  • The whiter,the higher of the alumina content
  • The Yellow one showed here is 68%
  • CGB which is widely used in ceramic batch mill for body biscuit grinding.


+Shaping difference 

According to  the shaping method, there are 2 types of CGB. Normally ,diameter lower than 30mm are made of rolling method and above 30mm are made of isostatic press method


+Diameter difference 

CBG can be made from 3mm to 120mm in diameter all depending on the clients requirement.In ceramic industry, the most used diameters are : 20mm,25mm,30mm,40mm,45mm,50mm,60mm,70mm


At begming, CBG beads made by rolling method widely used in China's cement plants. However,a huge quantity of breakage occurred,which cause disasterous result.After 4. years test and experience, now It's commonly believed that Pressed CBG is the better solution.


In order to cater to the cement ball mill need, CGB beads with diameter smaller than 30mrn are made through press machine. The big difficult lies in the capacity. as compared with rolling method, the daily capacity of pressed CGB beads are just around 1/5 of big balls. 


Five advantages of Alumina dry grinding ball replaces the high chromium steel ball applying to the cement grinding.


Energy Saving

  • Reduce over 40% of mill’s load capacity
  • Save over 20% energy for one ton of cement
  • Reduce over 30% energy of the mill main engine



  • Improve the efficiency of powder grinding;
  • Improve the capacity of cement;
  • Grain composition is more rational;
  • Improve the degree of spheric grain;
  • 3-32um particle contents improve more than 2 percentage points;
  • Standard consistency water consumption reduce 1-2 percentage points;
  • Cement is good for the concrete’s adaptability.


Lower the temperature and reduce the noise

  • The temperature inside the mill is reduce more than 20℃;
  • The noise of the mill is reduce about 20 decibel.


Abrasion Resistance

The ball consumption of Energy-Saving Dry Grinding Medium is 30% of the steel ball.


Environmental Protection

Energy-Saving Dry Grinding Medium is benefits for the achievement of the green manufacturing, which impeded the production of the water soluble chromium VI


There are basically 5 reasons that Chinese cement factories prefer alumina balls than chromium steel balls .

  • Reduction of Power consumption at 3-5kwh per ton pf cement output.
  • Improved cement quality .
  • Cement outlet temperature reduction of 20 degrees .
  • Less wear loss than steel balls loss
  • Environment friendly .
