ball mill lining brick 92% wear resistant lining ceramic alumina brick

Product Description
The high alumina lining brick can be divided into rectangular brick, trapezoidal brick and irregular brick as shape. The products has the high hardness, density, wear losses is very low, the heat degree very good, anti-corrosion, used for ball mill wear-resisting lining, widely used in ceramic, cement, paint, chemical, pharmaceutical, coating etc. and can effectively improve the grinding efficienty, reduce the grinding cost, reduce production pollution.
Calculation of alumina liner installed in ball mill (provided by qingdao sunrise energy-saving materials co., ltd.)
1. The number of alumina liners installed on two end walls:
(1) Calculation of the number of straight liners on the end wall:
Gf=3.14xr2÷(L1xW)
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=R1xR2, R1=3.14xD÷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 GC1and trapezoidal liner GC2according to the proportion in the table.

1. The material of installation:
The installation for lining Ball mill adopts silicate white cement and a little glue asadhesive.
2. The installation:
Before installation, we should clean surface of Ball mill.
(1)Installation should begin from the side walls installed with straight bricks totally and then adopt a certain number of semi- straight bricks to install matched. The gap between lining bricks should be less than 1.5mm. The installation of side walls should use straight bricks and semi-straight bricks only.
(2)After installing two side walls, then install round walls, which should adopt straight bricks and trapezoidal bricks. Make sure the bottom of lining bricks to contact tightly to the round walls, meanwhile use semi-straight brick and semi-trapezoidal liner to match (see the photo mentioned).
Specific installation steps are as following: Please install straight bricks first, then install trapezoidal bricks, at the last line, if the straight bricks can’t be inserted, then install fake bricks, whose gap is sealed tightly by white cement. Please let the workers install flexibly according to specific size of ball mill.
3. Maintenance:
After installation finished, we should maintain according to the following steps:Dry the ball mill naturally for two days and put pour full water into the ball mill for 3 days, then take the water out and naturally dry 7 days at least.After drying 7 days, pour water(occupying 70% of volume of mill)into ball mill, then charge alumina ball(occupying 60% of ball mill) and move ball mill for grinding 3 hours. Then move the ball mill the second time for grinding 1.5 hour. After 3 to 4 days, the ball mill could be normally operated.In winter, new installed ball mill should be heated for two days. On the first day, heat the ball mill by electronic stove for 24 hours, then move the mill and heat the other side for 24 hours. After that, maintain the ball mill as the steps of above mentioned.Packaging & ShippingOur Services
