1995	The original company of AOKEROLA GROUP, Zibo Yuanda Co. was founded.
1998	Incorporating with Spanish Refractory Institute, Weifang Aokerola Fine Cermaics Corporation was founded.
1999	Invented the isostatic medium alumina ball, and achieved the industrialization.
2000	Started the production of high alumina ball in the Weifang Plant
2001	Successfully developed the OK-Y686 iso-static ball press and won the national patent.
2002	Participated in making the National Quality Standard of Ceramic Roller in China.
2003	Successfully developed the low wear loss and low cost grinding media"Super Wear-Resistant King"
2004	Zibo Aokerola Ceramic Technology Co. Was founded.
2005	Zibo Plant started the production of medium alumina lining brick. And at the same time, Aokerola started the internationalization.
2006	Shandong Aokerola Technological Material Co., Ltd was founded, and successfully developed the global longest, full-automatic, intelligent medium alumina ball production line by high temperature roller kiln.
2007	Successfully built the unique biggest shuttle kiln for roller production, and introduced the cutting edge roller production technology from Germany inthe end of 2007.
2008	Started the production of high alumina ceramic by the High Temperature Roller Kiln, and achieved the Non-Quality-Difference production system, Which makes AOKEROLA become the first company which uses high temperature roller kiln to produce high alumina ceramic.
2010	The Fourth new high alumina ceramic production line is under construction and the Fifth new roller project is going to start.
2011	The new advanced low ware loss medium & high alumina grinding balls were brought into batch production.the medium alumina ball has been successfully replaced by the new developed high and medium alumina ball.

Guidence 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:

G_f=3.14×r²÷(L₁×W)

In the above formula: G_f: 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:

G_B=D÷W

In the above formula:

G_B: 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:

G_C=R₁×R₂ , R₁=3.14×D÷W , R₂=(L-2h)÷L₁,

in the formula:

G_C: 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: G_C: 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 G_C1 and trapezoidal liner G_C2 according to the proportion in the table.

Mill Tunnage	<0.3T	0.5T	1--1.5T	2.5--3T	5--25T	30--40 T
Stri. Brick:Tra.Brick	0:1	1:10	1:1	2:1	3:1	5:1

3. The total No. alumina liner:

Straight Liner=2G_f+ G_C1 Trapezoidal Liner = G_C2

Semi-Straight Brick=2G_B+ G_B1 semi-trapezoidal Brick= G_B2

Flake Brick= R₂

1. The material of installation:

The installation for lining Ball mill adopts 425# silicate white cement and a little 107# 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.
