FEATURES:

Higher density;

Higher hardness;

Higher wear resistance;

Higher grinding efficiency.

 

APPLICATION:

Used in high speed stirred grinding mills;

Ball mills as abrasive media for ceramic raw materials;

Glaze materials in ceramic factories, cement factories, enamel factories;

Used in glass work，owing to the excellence of high density, high hardness, and high wear rate. During the abrasive/grinding processing, ceramic balls will not break up，they will not pollute the grinded material as well;

The mix and crush procedure of ceramics, glass, glaze and frits, chemical and plastic industries.

 

How to optimize the grinding process in the situation of wet grinding:

Usually,the total charges of alumina ball in one ball mill should be not less than 55% of the total ball mill capacity.

Empirical formula of charged alumina ball quantity into ball mill

M=3.14×R2×D×L×25%÷1000

Remark:

M=charged alumina ball quantity(kg)

D=Alumina ball density(g/cm³)

R=Radius of ball mill

L=Ball mill length

Alumina grinding ball proportion

For a bright new installed ball mill, alumina ball’s proportion depends on the capacity of the ball mill and the fineness of the grinded raw materials.

Alumina ball recharge quantity

Recharge quantity=Primary ball quantity×ball wear loss×grinded time
