Description
Technical field
The present invention relates to ball mill accessories field, specially a kind of tumbling ball mill liner plate.
Background technology
The industrial trades such as coal, metallurgy, mine, electric power, building materials, refractory material and the energy carry out object extensively using ball mill
Material is crushed, and ball grinding machine lining board is most important abrasion attrition component, and the ball grinding machine lining board material used in every profession and trade mainly has at present
Several single metal materials such as potassium steel, Low Alloying Multicomponent Steels and Cr series white cast iron, without hard carbide in potassium steel, thus
Hardness is low, only under high load capacity and high impact stresses, realizes austenite to the solid-state phase changes of martensite and processing hardening, ability
Its wearability is given full play to, and in general operating mode, material is insufficient to allow potassium steel to generate the impact strength of ball grinding machine lining board
Drawing hardening effect, therefore wearability is not achieved ideal value, also without hard carbide in Low Alloying Multicomponent Steels, cannot resist abrasive material
Indentation and stroke, surface generates a large amount of cutting and flow low-cycle fatigue in use, therefore wearability is bad, the casting of chromium system
Although iron wear-resisting property is good, its plasticity and toughness difference is easily broken off, and due to monoblock cast, to consume a large amount of rare metal member
Element, comprehensive various aspects factor so that ball grinding machine lining board wear-resisting property currently on the market is poor, and repair and replacement are frequent.
For problem described above, a kind of tumbling ball mill that China Patent No. is proposed by CN201621327633.4
Liner plate solves these deficiencies substantially, but the program in actual practice or has some：Boss single pass-through spiral shell
Nail, mounting hole and the second threaded hole are installed, and loosening is easy to happen after working long hours, boss is made to be shaken in groove,
Being easy to happen failure makes normal work be affected.

Plate offers the second threaded hole in the groove, and is provided with screw in the second threaded hole, and the boss is internally provided with peace
Hole is filled, and mounting hole is aligned with the second threaded hole, the screw is interspersed in mounting hole and the second threaded hole, the boss packet
Shell base is included, and is provided with stiffener in shell base, and the surface of stiffener is fixedly welded with several steelframes, the shell
Base overhead surface is fixedly installed metal layer.
Preferably, the lower surface of the top plate and the inner wall bottom surface of groove offer spring groove, the compressed spring
Upper and lower side is arranged in respectively in the spring groove of top plate lower surface and groove inner wall bottom surface.
Preferably, the compressed spring is centrally located at the inner wall bottom surface of groove, and the second threaded hole is set to pressure
The both sides of contracting spring.
Preferably, the barb baffle plate setting has two groups totally four, and two groups of barb baffles about boss it is vertical in
Axis centre is symmetrical.
Preferably, the layer on surface of metal is provided with ceramic particle, and the upper surface of the lower face of metal layer and shell base
It is equivalent.
Compared with prior art, the beneficial effects of the invention are as follows：
1. baffle and barb baffle can play the phenomenon that preventing from shaking between boss and groove, compressed spring, barb baffle
Boss is set to keep stablizing with baffle mutual cooperation；
2. screw, peace annular distance and the second threaded hole have largely been shared in the effect that is mutually clamped of baffle and barb baffle
Between interaction force, so that it is less likely to be damaged slip teeth, prolong the service life.
Description of the drawings
Fig. 1 is schematic diagram of the present invention；
Fig. 2 is regional enlarged drawing at the present invention.
In figure：Substrate 1, the first threaded hole 2, groove 3, boss 4, baffle 5, barb baffle 6, compressed spring 7, top plate 8, spiral shell
Nail 9, stiffener 10, steelframe 11, metal layer 12.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
It please refers to Fig.1 to 2, the present invention provides a kind of technical solution：Including substrate 1, offered inside the both sides of substrate 1
First threaded hole 2, and substrate 1 opens up fluted 3 between two parties, and boss 4, and 3 inner wall inner wall both sides of groove are provided in groove 3
It is fixedly welded with baffle 5, the lower surface both sides of boss 4 are fixedly welded with barb baffle 6, and barb baffle 6 and baffle 5
Matching installation, 3 inner wall bottom surface of groove is fixedly welded with compressed spring 7, and the upper end of compressed spring 7 is fixedly welded with top plate 8,
The second threaded hole is offered in groove 3, and screw 9 is provided in the second threaded hole, boss 4 is internally provided with mounting hole, and
And mounting hole is aligned with the second threaded hole, screw 9 is interspersed in mounting hole and the second threaded hole, and boss 4 includes shell base, and shell
Stiffener 10 is provided in base, and the surface of stiffener 10 is fixedly welded with several steelframes 11, shell base overhead surface
It is fixedly installed metal layer 12.
Further, the lower surface of top plate 8 and the inner wall bottom surface of groove 3 offer spring groove, compressed spring 7 up and down
