Note: As the grinding media, at a comparable weight with grinding balls, alumina ceramic cylinders have an approx.14% greater surface than alumina ceramic grinding ball.


 3. Production process of High hardness 92 alumina ceramic grinding balls for agitator:




4. Application 

High hardness 92 alumina ceramic grinding balls for agitator are mainly used in ceramic, glaze, paint, zirconia silicate, aluminum oxide, quartz, silicon carbide, talc, building material, chemical, inks, kaolin, cosmetics,cement,and other materials grinding




High hardness 92 alumina ceramic grinding balls for agitator with high density which involve two types: Wet grinding and Dry grinding. 


Wet Grinding Instruction (Ceramic industry)
For wet grinding process,when charge of ball is up to 55% of net volume of the mill,the best status can be realized.
The volume of ball within the mill can be estimated with formula:
W—weight of ball(Kg)
R—radius of mill(cm)
D—bulk density of ball(g/cm3)
L—length of mill(cm)


For glaze grinding—raw material: ball=1:(1.8~2.0)


Special Note:Ball-Washing

While grinding glaze,in the case of charging the whole Ball Mill with new alumina balls,you are strongly recommended to complete the procedure namend Ball-Washing.It means you should let the whole batch of new alumina balls grinding themselves with water for more than 2 hours, then drain the water and the impurity from the Ball Mill.This is the preparative process recommended before grinding glaze by new balls.


For body material grinding—raw material: ball=1:(1.0~1.2)


Dry Grinding Instruction

The volume of raw materials=Effect capacity of mill×35%
The volume of ball=Effect capacity of mill×50%
