Alumina Grinding Ball

　　Usage:Wet grinding

　　Al2O3(%):92

　　Hardness(Mohs):9

Grinding media is characterized by:

　　Higher density;

　　Higher hardness;

　　Higher wear resistance;

　　Higher grinding efficiency.


Application Area

　　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.

Method of application:

　　Used in wet grinding method:

　　A. Final Assembly of ball in ball mills a total volume of 55%.

　　Empirical formula: M=3.14*R2*D*L*25%/1000

　　(Note: M= charged alumina ball quantity number of added alumina balls

　　D= alumina ball density(g/cm3)

　　D= alumina ball density (g/cm3) density of alumina ball

　　R= radius of ball mill

　　RADIUS r = radius of ball mill ball mill

　　L= length of ball mill

　　Length l = length of ball mill ball mill)

　　For a new installation of ball mill, loading specifications and dimensions of the ball depends on the size and weight of the ball mill.

　　B. Increase volume of ball = Initial amount of ball*Wear rate*Grinding time

Used in dry grinding methods:

　　Dry grinding is widely used in mining, ceramics, pow
