Abstract
The utility model is related to be used for metalliferous mineral, industrial mineral, chemical industry mineral, can protect a kind of shaped form autogenous tumbling mill and semi-autogenous mill liner plate of cylinder inner surface in source mineral and building materials material grinding autogenous tumbling mill and semi-autogenous mill.Shaped form autogenous tumbling mill and semi-autogenous mill liner plate (1) it is upper push the surface sections profile of load exercise be curve (2), (2) shape is one kind in Archimedes spiral, involute, parabola, helical, cycloid to curve.Since load is small compared with when being the apparent motion of straight line along cross section profile along the resistance for the apparent motion that cross section profile is curve, therefore shaped form autogenous tumbling mill and semi-autogenous mill liner plate (1) with usually used cross section profile be the liner plate of straight line (4) (3) compared with, it wears less, lasts a long time.
Description
Technical field
The utility model is related to be used to metalliferous mineral, industrial mineral, chemical industry mineral, energy source mineral and building materials material grinding use
In autogenous tumbling mill and semi-autogenous mill, a kind of shaped form autogenous tumbling mill and semi-autogenous mill liner plate of cylinder inner surface are protected.
Background technology
At home and abroad in the widely applied autogenous tumbling mill of metal mine and semi-autogenous mill, mill load includes ore and steel ball.
When work, as grinding mill barrel rotates, the granularity of mill load tumbling motion, ore is gradually reduced.To prevent load impact from grinding
Grinding mill barrel is damaged, inner barrel is both needed to installation liner plate.Traditional autogenous tumbling mill and semi-autogenous mill liner plate is linear type, is pushed thereon negative
The surface sections profile of lotus movement is straight line, as shown in Figure 4 and Figure 5.Since load is along the apparent motion that cross section profile is straight line
When resistance it is larger therefore more serious to the abrasion of backing surface, affect the service life of liner plate.
Utility model content
To extend the service life of traditional autogenous tumbling mill and semi-autogenous mill liner plate, the utility model proposes a kind of shaped forms certainly
Grinding machine and semi-autogenous mill liner plate.
Technical solution adopted by the utility model to solve its technical problems is：Using shaped form autogenous tumbling mill and semi-autogenous mill
Liner plate (1), thereon push load exercise surface sections profile be curve (2).(2) shape is Archimedes spiral, gradually opens curve
One kind in line, parabola, helical, cycloid.Liner plate (1) cross section profile can unilateral be curve (2), can also bilateral be curve
⑵。
The utility model has the beneficial effects that：Due to load along the resistance that curvilinear surface moves compared with being moved along straight line surfaces when
It is small, thus shaped form autogenous tumbling mill and semi-autogenous mill liner plate (1) with usually used linear type autogenous tumbling mill and semi-autogenous mill liner plate (3) phase
Than abrasion is less, lasts a long time.

Specific implementation mode
Embodiment 1.A kind of shaped form autogenous tumbling mill of the utility model and semi-autogenous mill liner plate embodiment, such as Fig. 1 and Fig. 2 institutes
Show, liner plate (1) it is upper push the surface sections profile of load exercise be curve (2), (2) shape is Archimedes spiral to curve.
According to processing drawing making autogenous tumbling mill or semi-autogenous mill liner plate casting mould.
Lining material selects bainitic steel.Dispensing, smelting, cast are carried out according to bainitic steel chemical composition.
The liner plate that casting is completed is heat-treated.
By a kind of shaped form autogenous tumbling mill of sufficient amount of the utility model and Semi-Autogenous of the manufacture of step according to the method described above
Machine liner plate is mounted in grinding machine, notices that grinding machine direction of rotation should ensure that liner plate upper section profile is a side surface of curve when installation
Push load exercise.Due to load, shaped form autogenous grinding small compared with when being moved along straight line surfaces along the resistance that curvilinear surface moves
Compared with usually used linear type autogenous tumbling mill and semi-autogenous mill liner plate, abrasion is less, lasts a long time for machine and semi-autogenous mill liner plate.
Embodiment 2.Another embodiment of the utility model a kind of shaped form autogenous tumbling mill and semi-autogenous mill liner plate, such as Fig. 2
Shown in Fig. 3, liner plate (1) upper section profile bilateral be curve (2), curve (2) shape be parabola.
According to processing drawing making autogenous tumbling mill or semi-autogenous mill liner plate casting mould.
Lining material selects bainitic steel.Dispensing, smelting, cast are carried out according to bainitic steel chemical composition.
The liner plate that casting is completed is heat-treated.
By a kind of shaped form autogenous tumbling mill of sufficient amount of the utility model and Semi-Autogenous of the manufacture of step according to the method described above
Machine liner plate is mounted in grinding machine.Due to load along the resistance that curvilinear surface moves compared with when being moved along straight line surfaces small, curve
Type autogenous tumbling mill and semi-autogenous mill liner plate wear less, the longevity compared with usually used linear type autogenous tumbling mill and semi-autogenous mill liner plate
Life is longer.
When grinding machine works, cylinder direction of rotation only makes on liner plate a side surface push load exercise, therefore the liner plate side table
More another side surface of surface wear is serious.When this side plate surface abrasion is to when should not be continuing with, thus it is possible to vary grinding machine turns to,
Or liner plate is exchanged into direction and is used, therefore the liner plate service life can reach nearly twice of unilateral shaped form liner plate.
Claims (3)
1. a kind of shaped form autogenous tumbling mill and semi-autogenous mill liner plate, are characterized in that：(1) liner plate above pushes the surface sections of load exercise
Profile be curve (2).
2. a kind of shaped form autogenous tumbling mill according to claim 1 and semi-autogenous mill liner plate, (2) shape is Archimedes to curve
One kind in helical, involute, parabola, helical, cycloid.
3. a kind of shaped form autogenous tumbling mill according to claim 1 and semi-autogenous mill liner plate, (1) cross section profile can be single for liner plate
Side be curve (2), can also bilateral be curve (2).
