Operation.Few loss for this reason it would be desirable to which the energy that ore mill is consumed can try one's best, so as to improve the grinding efficiency of ore mill.
With material directly contact it is milling medium steel ball and liner plate in ball mill.Milling medium steel ball can be shelled with mill
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
It is interior to change, 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 in maximization, 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 results 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.
Utility model content：
The technical problems to be solved in the utility model：A kind of grinding mill liner structure is provided, to solve the mill of prior art
Ore deposit machine lining plate structure improves ore grinding cost, influences the grinding efficiency of ball mill, also results in the technical problems such as the delay of production.
Technical solutions of the utility model：
A kind of grinding mill liner structure, it includes liner plate main body, and the liner plate body contours are regular hexagon, liner plate main body
On offer the first screw and the second screw, the first screw and the second screw hole dimensions are identical, and the first screw and the second screw are just
On the diagonal of hexagon, the first screw and the second screw are set along regular hexagon Central Symmetry.
Liner plate main body is globoidal structure.
First screw and the second screw are countersunk screw holes.
The beneficial effects of the utility model：
The liner plate of ball mill has advantages below using regular hexagon：First, compared with common liner plate, using positive six side
The liner plate better tightness of shape.The liner plate of regular hexagon can make splicing more close, will not cause the generation in gap.Due to ball milling
Machine drum body is cylindrical structure, therefore, and two ends need to be sealed using the liner plate of isosceles triangle, so that whole lining
Plate face and cylinder it is closely sealed, therefore the leakage of ore pulp will not be caused.Second, liner plate is that ore mill is attached to by the connection of bolt
On the inwall of cylinder, due to huge percussion, common liner plate can be produced in grinding process（Generally rectangle）Install
It is complete be typically all it is arranged in parallel, when liner plate is by uneven percussion, only part force bearing of lining plate will be produced relative
The changing of the relative positions, can be to the shear action of bolt, so as to damage bolt；Using the liner plate of regular hexagon, can make power suffered by liner plate to
Neighbouring liner plate is disperseed, thus between reducing liner plate with respect to changing of the relative positions phenomenon generation, so both ensure that the stabilization of liner plate
Property, also protect bolt without damage.The grinding mill liner structure for solving prior art improves ore grinding cost, influences ball milling
The grinding efficiency of machine, also results in the technical problems such as the delay of production.
