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:


   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:


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 GC2according to the proportion in the table.

Mill Tunnage

<0.3t< span="">





30--40 T

Stri. Brick:Tra.Brick







3. The total No. alumina liner:

Straight Liner=2Gf+ GC1           Trapezoidal Liner = GC2

Semi-Straight Brick=2GB+ GB1      semi-trapezoidal Brick= GB2

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 cant 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:

  1. 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.

  2. 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.

  3. 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.

Q:What is the high temperature limit of refractory bricks and refractory soil?
Fire clay -- usually refers to folk point stove furnace set with a kind of soil, limit under atmospheric pressure of 1500 degrees fire clay soil 1, properties and uses: clay brick of weak acid refractory material, its thermal stability is good, suitable for hot blast furnace, boiler and flue, smoke chamber lining, etc..2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.
Q:How to test the aluminium bricks of high alumina refractory bricks?
Before making bricks, the raw materials are usually tested and tested to see if the aluminum content is up to standard
Q:The difference between aluminium refractory and magnesia refractory
Therefore, the difference between the two is a neutral, one is alkaline, the original product is different naturally.
Q:What are the alloy wear resistance materials?
KNMn19Cr2 (patent) high manganese alloy (ZGMn13Cr2MoRe), super high manganese alloy (ZGMn18Cr2MoRe); two: anti-wear chromium cast iron series: such as high, medium and low chromium alloy cast iron (Cr15MOZCu); three: wear resistant alloy steel series: such as, low and high carbon multi metal combined steel (such as ZG40SiMnCrMO and ZG35Cr2MoNiRe); four: ADI (ADI) series; five: all kinds of composite or gradient material and hard alloy materials, nano KN alloy (patent product): such as chromium carbide composite (Cr2C3+Q235), high-energy ion osmosized tungsten carbide materials (WCSP), high toughness of cemented carbide (YK25.6), KN999 nano alloy (Beijing Naimo patent) etc.;
Q:What is the standard size of high alumina brick?
The country has laid down a number of criteria for the use of refractory bricks to unify market demand.
Q:What are the specifications for bricks?
Ordinary brick size of 240 mm * 115 mm * 53 mm, according to compressive strength (Newton / square millimeter, N / mm2) size is divided into MU30, MU25, MU20, MU15, MU10, MU7.5, these intensity levels. Clay brick materials, cheap, durable, and fire prevention, heat insulation, sound insulation, moisture absorption and other advantages, is widely used in civil engineering. Waste brick can also be used as aggregate of concrete. In order to improve the shortcomings of ordinary clay bricks, such as small, self important and waste of soil, they are developing in the direction of light weight, high strength, hollow and big blocks.
Q:Which is faster for heat transfer between corundum bricks or high alumina bricks?
75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more. 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.
Q:What are ordinary bricks, refractory bricks, hollow bricks?
Referred to as refractory brick. Refractory wood made from refractory clay or other refractory material
Q:The difference between ordinary and diatomite brick refractory brick
Refractory brick belongs to a large class, according to different materials used are divided into: high alumina brick, dolomite brick, magnesia chrome brick, magnesia spinel brick, phosphate brick, carborundum brick, brick, mullite bricks etc..
Q:What is the difference between corundum and high alumina??
The main components of high alumina brick are high alumina bauxite, mullite and partial corundum sand.
