Product Description

Alumina grinding media

Al₂O₃(%)≥92

Rate of Water Absorption(%) ≤0.01

Bulk density(g/cm³) ≥3.63

Product Description

Vanna grinding media is characterized by :

Extremely cost effective;

Improves grinding efficiency and energy costs;

Longer service time due to low wear rate;

Contamination-free to the color and composition of the ground material;

Technical support provided to optimize milling conditions.

APPLICATION

1.In the situation of wet grinding

Usually,the total chaarges of the alumina balls should be not less than 55% of the total ball mill capcacity

Ball capacity(MT)	Crinding raw materials	Feeding size	proportion
>15MT	Greem body	>1.5cm	Φ30:Φ:40:Φ50:Φ60 2:3:3:2or2:4:3:1
2.5MT,5MT	Glaze		Φ30:Φ:40:Φ50:Φ60 3:4:2:1
	Glaze		Φ30:Φ:40:Φ50 3:5:2

2.in the situation of dry grinding

Dry grinding is widlely used in mining,ceramic industries,etc.VANNA technicans make lots of tests,eventually,we developed alumina balls performd well on dry grinding situation with much lower wear-loss,it help solve the problem of materials contamination.

The proportion of the alumina ball for dry grinding depands on the hardness and fineness of grinding raw material,generally speaking,CIP formed grinding ball used for dry grinding.
