4. Advantages

(1) Core Technology:

Using the global best alumina grinding ball production technology originated from our over 12 

years working experience as well as our frequent technical research. This core technology 

enable us to  produce high quality products continuously to satisfy the requirement of our 

global partners. 

(2) Production system&equipment:

we are using high temperature roller kiln (totally 2 kilns with each 250 meters length and

Max.1650 degree centigrade) to sinter the alumina ball, which enable us to producer higher

and more stable quality alumina ball due to the temperaturedifference of roller kiln is much 

smaller than that of tunnel kiln used by other manufacturers. The prominent features of 

alumina ball sintered by roller kiln are : 

1) higher density  2) lower wear loss  3) more stability of quality  

(3)Important Technical data:

We are producing our alumina ball with the following standard:

The above mentioned technical data plays the most important role in the during the production of ceramic and also the most important factors to the reduction of production costs.
