Application of Al2O3 Alumina Ceramic Balls for Ball Mill

How to optimize the grinding process in Ball Mill for Alumina Ball:
1. In the situation of wet grinding
Usually,the total charges of the alumina balls 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=3.14xR2xDxLx25%+1000
Remark M= charged alumina ball quantity(kg)
D=Alumina ball density(g/cm)
R=Radius of ball mill L=Ball Mill LengthAlumina grinding ball proportion:
For a bright new installed ball mill, the alumina balls proportion depends on the capacity of the ball mill and the fineness of the grinding raw materials

Alumina ball recharge quantity
Recharge quantity=Primary ball quantity*Ball wear loss*Grinding time



2. In the situation of dry grinding:
Dry grinding is widely used in mining, ceramics industries, we developed alumina balls performed well on dry grinding situation with much lower wear-loss, it helps solve the problem of materials contamination.
The proportion of the alumina ball for dry grinding depends on the hardness and fineness of the grinding raw material, generally speaking, CIP formed grinding ball used for dry grinding.
Wear-loss testing method of alumina ball:
This method is the Chinese domestic testing method, put alumina ball samples into polyurethane jar, testing the wear loss in the unit time.
Firstly, put 4kg alumina ball and 4L water into the grinding jar, put the jar into the testing machine, grinding 2h on the revolution of 80 r/min. Take out the samples dry them and get weight M1.
Secondly, put the above samples again into the jar, add 4L water, grinding 24h on the same revolution of 80 r/min.
Thirdly, take out the samples dry and get weight M2.
Fourthly, testing the average diameter of the samples, get average diameter D.
Fifthly, wearloss calculation:
EWT(%o )=KD M 1-M2 )M 1
Empirical formula: EWT(%o)= (M1-M2)M1/24 /100*1000*D
