High Alumina Ceramic Ball, Brand Name : vanna

We are offering Alumina ceramic ball
　　Al₂O₃(%)>92
　　Bulk density(gcm³)>3.65
　　Wear rate(%)≤0.005
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 abrasivegrinding 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(gcm3)
　　D= alumina ball density (gcm3) 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:
