3. Ceramic Alumina Grinding Balls Application
Ceramic grinding balls mainly used in ceramic,porcelain glaze,glass,chemical industry. It is the grinding medium for ball mill,pot mill,vibration mill and other fine powder grinding equipment,its grinding and wear resistant efficiency is much better than the normal ceramic ball and nature stone.Mainly used in ceramic,porcelain glaze,glass,chemical industry.
It also can be used for polishing of metal parts and grinding for nonmetal minerals powder(such as zirconium silicate powder,kaolin etc.).It can used in all type of grinding and polishing machine.
4. Ceramic Alumina Grinding Balls Manufacturing process
Alumina ball is made from high quality material with high tech cool isostatic
pressing technology and under the high temperature calcined .
5. Ceramic Alumina Grinding Balls Feature
Alumina balls are made from good quality and high temperature alumina powder with the characters of high degree purity ,high intensity high hardness ,more white and less wear abrasion and no effect for the grinded materials .
Alumina ball is isostatic pressed with high density ,it can increase grinding efficiency , reduce grinding time and increase effective volume of grinding mill ,thereby increasing the amount of grinding material .
Alumina balls have very lower wear resistance can greatly prolong the service life of grinding medium .
It also have the properties of high temperature resistant ,acid and alkali resistant ,corrosion resistant . Researched and developed the alumina balls for dry grinding with the character of lower wear resistance and good tenacity and solved the problem of materials pollution from the grinding media .
6. Ceramic Alumina Grinding Balls Test
①Factory test
Ceramic alumina balls test is an very important step. Real-time detection will be carried out in the production process. Alumina balls produced in each shift will be sampled in large quantities and tested to ensure the quality of grinding balls.
②The third party test
According to the customer different demand,alumina balls can be tested by any third party.

8. Factory History
Dragon balls factory are established in 2001.Up to now, we have cooperated with many large power plants in China for more than 10 years. Since 2007, Dragon balls has set up its own foreign trade team, and began to show itself to the world. The forged ball, cast ball ,cylpebs and high alumina balls are widely praised by friends at home and abroad.
Dragon balls has a very mature technology research and development team and sales team, we are constantly expanding the factory and team every year, in order to meet the growing demand at home and abroad.
Grinding balls are a long-term business.
We are willing to do it all the time because if we know someone, we will become permanent friends.
We can always do this for so many years because our quality supports our long-term cooperation and friendship.
The quality of every grinding ball is crucial because it is a strong bridge that connects us.
