Description
Technical field
The utility model relates to inner wall of ball mill drum lining plate structure technical fields.
Background technique
Ball mill is that material carries out the key equipment crushed again after coarse crushing.It is mounted on inner wall of ball mill drum
On the one hand liner plate is to protect it from abrasive body and material for protecting ball mill barrel and directly impact and wear, be on the other hand
As lifting strip improving material, to improve the motion state for leaving height and abrasive body (medium ball) of material, with enhancing
Abrasive body acts on the grinding of material, improves ball mill crush efficiency, and reduce the metal consumption of medium ball, energy-saving.
Existing ball mill barrel interior lining panel form is more, as the Chinese patent of Publication No. CN201664622U discloses
Ball grinding machine lining board, split type liner plate disclosed in CN203408762U promote one kind disclosed in bar assembly, CN204051810U easily
Dismantle ball mill rubber lining lifting strip disclosed in ball grinding machine lining board, CN202490657U etc..The lifting strip structure of these liner plates
Height radially is identical, cause in ball mill operation process can not the medium ball to different-diameter promoted well,
So that ball mill grinding efficiency is not high；And these liner plates and ball mill barrel are to contact firmly, when ball mill works, medium ball with
Under the impact of mineral aggregate, very big impact is brought to ball mill ontology, so that the connection between liner plate and ball mill barrel is easy
Failure is loosened, while generating very big noise, causes great noise pollution.Although CN202490657U patent therein considers
Arrived the material using rubber as liner plate, but rubber as a kind of biggish material of flexibility in the grinding machine course of work not
There can be preferable castering action to the biggish medium ball of quality and mineral aggregate, and abrasion easily occurs and loses enhanced feature.
Summary of the invention
Purpose of the utility model is to solve the deficiencies in the prior art, and medium ball and material pair can be reduced by providing one kind
The impact of ball mill barrel, damping noise reduction effect are good and promotion effect to medium ball can be improved, and improve mill grinding efficiency
Rubber-metal composite globe mill inner wall of rotary drum liner plate.
The utility model is as follows by the following technical solution taken:
A kind of rubber-metal composite globe mill inner wall of rotary drum liner plate, including be arranged in ball mill barrel inner wall one circle with
The gold identical with barrel lenght that the identical rectangular slat rubber shock-absorbing item of barrel lenght, one-to-one correspondence are pressed on rubber shock-absorbing item
Belong to stepped lifting strip；The back side that the step type lifting strip and rubber shock-absorbing item are affixed is arcwall face, towards the surface of the cylinder heart
For raised cascaded surface step by step；Mounting hole is offered at the both ends of every slat gum shock absorption strip, in the back of every stepped lifting strip
The T shape through slot that face is opened up along lifting strip length direction, the bolt head for connecting bolt are fitted in T shape through slot, and screw rod passes through damping
Mounting hole, the screw rod outer end for connecting bolt is fitted with nut.
Step type lifting strip described in the utility model is provided with level Four step, and the height of steps at different levels from low to high is step by step
Increase.The height of the minimum level-one step of the step type lifting strip is greater than the smallest primary medium ball of balling drum interior diameter
Radius, the height of second level step is greater than the radius of second largest secondary medium ball of diameter, and the height of third level step is greater than
The radius of the third-largest three-level medium ball of diameter, the height of fourth stage step are greater than the radius of the maximum level Four medium ball of diameter.
The utility model has the following beneficial effects:
1, the stepped lifting strip of the utility model and the design of damping rubber block fission, and pass through bolt and ball mill barrel
Connection, is easily installed maintenance, is set to the damping rubber block between cylinder and lifting strip and on the one hand makes between liner plate and cylinder
Contact it is even closer securely, on the other hand reduce the impact of medium ball and material to cylinder, have the effect of energy-saving and noise-reducing；
2, stepped lifting strip structure can the medium ball to different-grain diameter in cylinder promoted step by step, eliminate and show
Have that hoisting depth existing for the height liner plate such as technology is low, promotes less effective and the low problem of grinding efficiency, very big the improves
Promotion effect of the liner plate to medium ball improves mill grinding efficiency.
