Abstract
The utility model discloses a kind of ball mill center liner blank compensation apparatus, including fixed block, connecting bolt and compensation block.Wherein fixed block and compensation block are cast steel structure, and connecting bolt is interior hexagonal dormant bolt, and fixed block is rectangular boss structure, and boss top is isometric with center liner, and width is identical, and boss bottom is slightly longer than top.The part to be grown below fixed block boss can be inserted into the gap below end cap grid liner plate, then fixed block be weldingly fixed on one of center liner in the side for having chamfering structure, and compensation block is to be secured it in by connecting bolt on fixed block.So, ore pulp, ore particle all wear-compensating blocks, will not directly be contacted with fixed block, and the weld of fixed block and center liner would not be worn, it is ensured that the service life of compensation device.When need to change broader compensation block simultaneously, Zhi Xu Panasonics connecting bolt, broader compensation block, then fastening bolt are changed, was both facilitated, but it is time saving and energy saving.
Description
Technical field
A kind of ball mill center liner blank compensation apparatus is the utility model is related to, belongs to ore grinding servicing unit technology neck
Domain.
Background technology
Ball mill is that current non-ferrous metal ore factory uses most common grinding attachment.
The discharging portion of ball mill is made up of ore discharge end cap, grid liner plate, dustpan liner plate, center liner etc., in ore discharge end cap
End cap with quill shaft is built with discharging lining and ore discharge grid, and ore discharge grid is by center liner, grid liner plate, dustpan liner plate
Composition.
Due to ball mill, day and night ceaselessly steel ball ceaselessly hits liner plate in centrifugal force and ball mill caused by rotation, with
And ore pulp continuously outflows caused abrasion, make grid liner plate, center liner slowly to ball mill outer end move.Normal condition
Under, the gap between the liner plate and liner plate newly installed is in 5-15mm or so.Ball mill is after the 20-30 working day that work, each seam
Gap is basically stable at 0-10mm, and other gaps are all added between two pieces of center liners, and at this moment the gap of center liner is in 20-
25mm or so.With the extension for time of driving, ore pulp, little particle ore are ceaselessly passed through with more than 100 tons per hour of flow
The various outside overflows in gap, so that various gaps are constantly worn, also the distance between two pieces of center liners are constantly expanded,
Typically in or so half a year, its gap can reach more than 35mm,（To the end of the year, its gap can exceed 70mm）At this moment just have with ore grinding
The small ball of ability overflows.A part has the small ball of grinding capacity can influence ball mill ore grinding fineness and ore grinding after overflowing
Ability, it is therefore necessary to handled.Traditional processing method：1st, according to the distance of two pieces of center liners, from corresponding square steel
As compensation block.2nd, the length of compensation block is grown as center liner.3rd, compensation block is carried out complete with one piece of center liner therein
Welding（Welded with one of center liner slightly more longer than welding its service life with two pieces of center liners）.Traditional place
The defects of reason method is：a）Service life is short：On the one hand, due to abrasion of the ore pulp to weld；On the other hand, welding material
Matter is crisp, and because steel ball strike is often broken, its life-span is typically at 2 ~ 3 weeks.b）It is big to change compensation block workload, working environment
Badly.On the one hand, the weld seam of fracture must be cleaned out, and then weld again, therefore replacing compensation block typically needs 6 ~ 8 hours；Separately
On the one hand, narrow space in ball mill, operating difficulties, and improper ventilation, weldering cigarette are difficult to discharge, bad environments.c）Compensation block
Once ball mill intracavitary will be entered by coming off, it is easy to broken other liner plates in ball mill, and cleared out compensation block sometimes also
It is relatively time consuming.
The content of the invention
The purpose of this utility model is：There is provided it is a kind of it is practical, conveniently, the ball mill center liner gap of service life length mends
Repay device.
The technical solution of the utility model
A kind of ball mill center liner blank compensation apparatus：Including fixed block（1）, connecting bolt（2）And compensation block（3）,
It is characterized in that：Fixed block（1）And compensation block（3）All it is cast steel structure.Fixed block（1）For rectangular boss structure（See Fig. 4,5,
6）, boss top and center liner are isometric, boss bottom width same with top and slightly longer than top.The portion that so boss bottom is grown
Divide pluggable ball mill grid liner plate（5）Under gap.Fixed block（1）The unilateral chamfering in top, bevel edge fixes welding during installation
One piece of center liner wherein（4）On.Compensation block（3）For rectangle（See Fig. 7,8,9）, bottom surface is unilateral chamfering structure.Installation
When compensation block（3）And fixed block（1）Chamfering be placed in the same side, such as Fig. 3, its right side formed space be used for stacked solder shared by
Space, to ensure fixed block（1）And compensation block（3）Can closely it connect, compensation block（3）With fixed block（1）Boss top two
End alignment, bevel edge alignment, two asymmetric connecting holes are bored at both ends.Fixed block（1）It is processed as a hole, compensation block（3）It is processed as
Counterbore.Fixed block（1）With compensation block（3）Pass through connecting bolt（2）Connection, to ensure connecting bolt（2）Head, which is slightly less than, to be compensated
Plane on block.For protecting bolt head not worn by steel ball and ore pulp, it is easy to the renewal of compensation block.So both ensure connection
Reliability, it is easy to dismount again.
