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.

SPECIFICATION

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, powders and other industries. Wear of grinding media for split industry pollution of raw materials, we developed the dry grinding ball of low toughness, wear, solves the grinding media of widespread pollution problems of raw materials.

Dry grinding with grinding ball ratio depends on the raw material of hardness and the grinding of rough, usually by isostatic molding grinding balls.
