Abstract
The invention provides an integrated installation method for a lining of a ball grinder, belonging to the technical field of the lining of the ball grinder. The invention abandons a traditional installation manner of building one by one; an integrated block is firstly manufactured outside a barrel body and manual pressing is cancelled when the block is assembled; then a pressing machine is used for pressing so that the uniformity of pressure is guaranteed; after the block is completely manufactured, the block is transferred to the barrel body of the ball grinder to be mounted; before the lining is mounted, a plurality of supporting columns are bonded on the inner wall of the barrel body of the ball grinder in advance; when the block of the lining is clung to the inner wall of the barrel body, one gap is separated by the supporting columns; and then a binding agent is fully filled into the gap so that the block of the lining is mounted. By adopting the integrated installation method for the lining of the ball grinder, the influences on the construction quality by manual factors are reduced to the minimum and the installation quality of the lining is guaranteed to the greatest extent; compared with a traditional lining installation manner, a lot of installation time can be saved; and meanwhile, safety accidents can be prevented and the safety of constructors is guaranteed.
Description
Technical field
The invention belongs to inner liner of bowl mill technical field, particularly relate to a kind of inner liner of bowl mill integrated installation method.
Background technology
Ball mill is after material is broken, carry out the key equipment pulverized again, as the cylindrical shell of one of ball mill key building block, the grinding performance of installation quality to ball mill of its liner has a significant impact, and the installation quality of liner is mainly subject to the impact of liner installation process.
Present stage, the installation of liner is by manually completing, and due to the impact resistance special to liner, many stone, high-alumina brick, middle aluminium brick or the zirconia bricks cut into by lithotome of liner form, and are formed by artificial one piece one piece assemble.
Because the technical merit of workmen is uneven, the instability of construction quality will inevitably be caused, and the existence of human factor is almost inevitable on the impact of construction quality.
The human factor affecting construction quality comprises:
1. workmen is when assembling liner tile, and hand pressing force is uneven;
2. workmen is when assembling liner tile, and the use amount of bonding agent is uneven;
3. workmen is when assembling liner tile, and the size of liner tile selects mistake.
The construction quality problem caused by above-mentioned human factor comprises:
1. inner lining surface out-of-flatness;
2. liner tile distributes irregular and occurs gap;
3. the loosely bonding and loose or dislocation of certain block liner tile.
For above-mentioned construction quality problem, if inner lining surface out-of-flatness, liner tile distribution are irregular and occur gap, the resistance to impact of liner will be caused to reduce, time serious, probably occur that liner tile comes off, have a strong impact on the grinding performance of ball mill.
If meet with the bonding liner tile loose or dislocation loosely caused of liner tile in the liner installation stage, very likely workmen is caused serious injury.
Summary of the invention
For prior art Problems existing, the invention provides a kind of inner liner of bowl mill integrated installation method, can the impact of human factor on construction quality be dropped to minimum, at utmost ensure the installation quality of liner, compared with traditional liner mounting means, a large amount of set-up times can be saved, also can prevent the generation of security incident simultaneously, ensure the safety of workmen.
To achieve these goals, the present invention adopts following technical scheme: a kind of inner liner of bowl mill integrated installation method, comprises the steps:
Step one: liner determines size and the kind of monolithic liner tile before installing;
Step 2: the usage quantity determining its liner tile according to the cylinder area of bed of ball mill barrel;
Step 3: ball mill barrel outer assembled go out cylinder head liner, and repair the liner tile at cylinder head liner round edge place, the diameter dimension of liner conformed to cylinder head diameter;
Step 4: according to size and the weight of liner tile, is lining with and marks off some blocks, comprise some liner tile in each block in cylinder head;
Step 5: by some block number consecutivelies of cylinder head liner, again numbered some blocks are individually assembled, assemble after adding bonding agent between each liner tile in process, press no longer manually, and utilize press to press, ensure the even of pressing force, the pressure limit of press is between 0.1Mpa ~ 1000Mpa;
Step 6: according to the size of stack shell size determination liner and the usage quantity of liner tile thereof of ball mill barrel;
Step 7: stack shell liner is divided into some blocks, comprises some liner tile in each block;
Step 8: by some block number consecutivelies of stack shell liner, again numbered some blocks are individually assembled, assemble after adding bonding agent between each liner tile in process, press no longer manually, and utilize press to press, ensure the even of pressing force, the pressure limit of press is between 0.1Mpa ~ 1000Mpa;
Step 9: after cylinder head liner block and stack shell liner block have all manufactured, just can be transplanted on each liner block in ball mill barrel successively and install.
Before being installed on ball mill barrel by liner, need prior bonding some support columns on the inwall of ball mill barrel, and ensure at least corresponding support column of each liner block, or directly at the bonding some support columns in each liner block back side.
The shape of described support column is circular or square, and the height of support column is 1mm ~ 50mm.
When installing liner block, selected block makes it abut in ball mill barrel correspondence position, and support column can will intercept out a gap, then filling adhesive in gap between block and cylinder inboard wall, and binding agent must be filled full, ensures the resistance to impact of liner.
Described stack shell liner block, according to the difference of stack shell size, has three kinds of versions, comprises annular, circular arc and picture combination.
When the inconvenient scene of liner tile at cylinder head liner round edge place is repaired, according to the size of cylinder head liner, ready-made special-shaped fragment of brick can be produced in advance, with the requirement of the diameter dimension of satisfied cylinder head liner.
Described special-shaped fragment of brick comprises the different triangular brick of some sizes and is highly less than the thin liner fragment of brick of calibrated altitude.
Beneficial effect of the present invention:
The present invention compared with prior art, provide a kind of brand-new inner liner of bowl mill integrated installation method, compared to the mounting means assembling liner tile of traditional a piece a piece, then first outside cylindrical shell, produce integrated block, and eliminate artificial pressing during assembling block, then adopt press to press, ensure the even of pressing force; After block has all manufactured, then be transplanted in ball mill barrel and install; Before carrying out liner installation, prior bonding some support columns on the inwall of ball mill barrel, or directly at the bonding some support columns in each liner block back side, a gap can be intercepted out by support column after liner block reclines cylinder inboard wall, then in gap, fill full binding agent, realize the installation of liner block.Adopt inner liner of bowl mill integrated installation method of the present invention, can the impact of human factor on construction quality be dropped to minimum, at utmost ensure the installation quality of liner, compared with traditional liner mounting means, a large amount of set-up times can be saved, also can prevent the generation of security incident simultaneously, ensure the safety of workmen.
