ADVANTAGE ANALYSIS:
(1)AL2O3 is the main content,high purity。(2)Fine Wear Resistance, 1/4 to natural liner。(3)High purity ,thinner slurry。(4)Fine corrosion resistance, high density, high mechanical strength
GUIDANCE FOR USING:
Calculation of alumina liner installed in ball mill
1. The number of alumina liners installed on two end walls:
(1) Calculation of the number of straight liners on the end wall: Gf=3.14×r2÷(L1×W)
in the above formula: Gf: the number of straight bricks on the end wall of ball mill
r: the semi-diameter of the end wall of ball mill
W: the width of lining bricks L1: the length of lining bricks
(2) Calculation of number of semi-straight bricks on the end face: GB=D÷W
In the above formula: GB: the number of straight bricks on the end face.
D: the diameter of the end wall W: the width of alumina liner
2. The calculation of number of liner on the round wall.
The total No. of liners: GC=R1×R2 , R1=3.14×D÷W , R2=(L-2h)÷L1,in the formula:
GC: The total number of straight bricks and trapezoidal bricks on the round wall.
R1: the rows of bricks on the round wall. R2: number of bricks in each row
D: the diameter of the end face h: the thickness of liner L: the length of Ball mill
W: the width of alumina liner L1: the length of liner
Remark: GC: calculation of the total number of straight bricks and trapezoidal bricks according to tonnage of Ball mill according to the following table. Respectively calculate the No. of straight liner GC1 and trapezoidal liner GC2 according to the proportion in the table.
