Effect and taper into, by mill stripping milling medium to it is certain when can take cylinder out of with the motion of material；But mill
The liner plate of ore deposit machine is integrally fixed on cylinder, it is impossible to cylinder is discharged with the motion of material, it is therefore desirable in the regular hour
Interior replacing, because lining plate replacing workload is big, in actual production, it is intended that the time of lining plate replacing, the longer the better.
Conventional liner plate is shaped as rectangle in ball mill.Because modern benficiation machinery tends to maximization, in ball mill
Liner plate need substantial amounts of steel ball and material lifting to certain height, therefore the load of liner plate is increasing；And it is adjoint
The characteristics of the steel ball and uneven material movement of motion in cylinder so that force bearing of lining plate is uneven, and liner plate ruptures in cylinder
Speed with deformation is more and more faster.Along with the deformation and rupture of liner plate, can cause again the bolt for fixing liner plate occur shearing and
The effect of moment of torsion so that the frequency that liner plate is changed in production is more and more faster, and the life-span that liner plate is used is shorter and shorter.The replacing of liner plate
Substantial amounts of man power and material is needed, ore grinding cost is so not only substantially increased, the grinding efficiency of ball mill is influenceed, also resulted in
The delay of production.Therefore, the cycle of liner plate is changed in extension, reduces the consuming cost of liner plate, and then improve the service life of liner plate
It is an important research topic.

After step 2. installs the first liner plate main body, in the installation of the square upstream sequence parallel to the first liner plate main body
Two liner plate main bodys, so repeat to install, until installing a week of cylinder, just can guarantee that head and the tail are fully connected；
Step 3. is after one week liner plate is installed, then installs the 3rd liner plate main body of empty portions between two liner plates, equally
Install one week, so repeat to install each block of liner plate of regular hexagon；
Step 4. is last, and the vacancy of triangle is left in a weekly assembly of cylinder two end cap, and isosceles are closely installed in vacancy
4th liner plate main body of triangle, completes the installation of liner plate.Beneficial effects of the present invention：
The liner plate of ball mill has advantages below using regular hexagon：First, compared with common liner plate, using regular hexagon
Liner plate better tightness.The liner plate of regular hexagon can make splicing more tight, will not cause the generation in gap.Due to ball milling machine barrel
Body is cylindrical structure, therefore, two ends need to be sealed using the liner plate of isosceles triangle, so that whole liner plate face
It is closely sealed with cylinder, therefore the leakage of ore pulp will not be caused.Second, liner plate is that ore grinding machine drum body is attached to by the connection of bolt
Inwall on, due to huge percussion, common liner plate can be produced in grinding process（Generally rectangle）Install one
As be all arranged in parallel, when liner plate is subject to uneven percussion, only part force bearing of lining plate will be produced relatively wrong
It is dynamic, can be to the shear action of bolt, so as to damage bolt；Using the liner plate of regular hexagon, the power suffered by liner plate can be made to attached
Near liner plate is disperseed, so as to reduce liner plate between with respect to changing of the relative positions phenomenon generation, so both ensure that the stability of liner plate,
Also protect bolt without damage.The grinding mill liner structure for solving prior art improves ore grinding cost, influences ball mill
Grinding efficiency, also result in the technical problems such as the delay of production.
