Microcrystal Alumina Lining Brick

 

Characteristics:
Microcrystal Alumina Lining Brick are high grade grinding media made by advanced Cool Isostatic Pressing Technology and fired at high temperature. With overwhelming merits in higher density,more regular shape, easy installing,superior grinding efficiencies and competitive price prior to natural cobble-stones and conventional grinding media, Sinoshine alumina grinding media are excellent for grinding processing of ceramic bodies and glaze materials in tile industries.

Application:
Being the wear-resistant liner for the ball mill, alumina lining brick is the best choice to increase the grinding efficiency and reduce the grinding cost. Currently, alumina lining brick is being widely used in ceramic, cement, paint, pigment, chemical, pharmacy and coatings industries.

 

Guidance For Using:

Description:Calculation of alumina liner installed in ball mill
1. The number of alumina liners installed on two end faces:
(1)Quantity of rectangle liners on the end face: S=3.14×R2÷(L1×W)
Remarks:                                                                                                                
S: the number of rectangle bricks on the end face 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) Quantity of half-rectangle bricks on the end face:S1=D÷W
Remarks:
S1: the number of half-rectangle bricks on the end face.
D: the diameter of the end face .
W: the width of alumina lining brick

2. The quantity of alumina liner installed on the cylinder:
(1)   The total of liners:  S2=P1×P2   P1=3.14×D÷W , P2=(L-2H)÷L1
Remarks:
S2: The total number of rectangle bricks and trapezoidal bricks on the cylinder..
P1: the rows of bricks on the cylinder. P2: 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 alumina liner.

Remarks:
S2: The total number of rectangle bricks and trapezoidal bricks comes from the tonnage of Ball mill in the following table. Base on the proportion in the table calculating the quantity of rectangle liner S21 and trapezoidal liner S22 according to the proportion in the table.

(2)The total No. alumina liner:
Rectangle Liner=2S+ S21  Trapezoidal Liner = S22
Half-rectangle  Brick=2S1+ S31  Half-trapezoidal Brick= S32
Flake Brick=P2.
