Description
Technical field
The present invention relates to benficiation machinery equipment technical field, particular for one kind of large-scale overflow type ball machine shell liner
New arrangement mode.
Background technology
Overflowball mill has had the history of more than 100 years as traditional milling equipment, and it is as by solid material
The visual plant of refinement powder processed, is widely used in metallurgy, chemical industry, cement, ceramics, building, electric power, medicine and national defense industry etc.
Ore dressing department in department, especially metallurgical industry, grinding operation is even more to have highly important status.Due to ball mill processing
Granularity after ability and grinding influences notable to the efficiency of subsequent job and the technical-economic index of overall production procedure, using height
Effect large scale equipment is the main tendency that modern ore dressing plant is built, and the maximization of ball mill has turned into the direction that technology develops, intensity
High ore is entered in large-sized grinder again, by grinding, crush all will turn into it is powdered, only in this way, low-grade ore with
And ore can realize recycling.At present on the market the shell liner of all large-scale overflow ball mill be all it is smooth, this
Sample is for so to the use of its liner plate very big influence, it is impossible to accomplishes the same cycle and is changed with the life-span, substantially reducing makes
Use the life-span.
By taking the overflowball mills of Φ 5500 × 8500 as an example, the equipment is main by cylindrical tube, bearing and transmission canine tooth
The parts such as circle composition, in process of production, rushing down, leave and centrifugal motion due to milling medium and nugget are produced larger
Kinetic energy, forms continuous impact to lining board of grinder and impacts, especially more tight to charging aside-liner and discharging aside-liner impact
Weight, causes wear liner, liner plate needs to change by the cycle.Feed end is crest, trough phase after being installed with discharge end shell liner
Between horizontal uniform thickness with height, stack pile configuration, but due to feed end first lap, second circle wear liner speed and degree the most
Seriously, the circle of feed end the 3rd, the four circle rates of wear and degree are more serious, and the circle of feed end the 5th and discharge end shell liner are almost
For uniform wear.There is the nearly difference of 4 months with discharge end shell liner service life in feed end shell liner service life,
Liner plate can not realize that same life-span and the same period are changed.
The content of the invention
It is an object of the invention to provide a kind of large-scale overflow ball mill novel barrel liner plate, to realize in large-scale overflow ball milling
In machine input and output material end shell liner abrasion as far as possible constant speed equal thickness wear and tear, finally realize the input and output material end shell liner same life-span,
In the same cycle, the frequency for changing shell liner, reduction repair time and maintenance workload are reduced, the time of effectively driving is improved, realized
Treating capacity and economic benefit largest optimization.
To meet above-mentioned purpose, the technical scheme is that：
The shell liner being provided with a kind of large-scale overflow ball mill novel barrel liner plate, including cylinder, the cylinder, the cylinder
Feed end shell liner for step type, the stepped shell liner be respectively first lap, second circle, the 3rd circle, the 4th circle,
5th circle and discharge end, wherein first lap and the second circle thickness are identical, and the 3rd circle is identical with the 4th circle thickness, and the 5th encloses and discharge
Hold thickness identical, the first lap is than the 5th circle thickness increase by 28%, and the 3rd circle is than the 5th circle thickness increase by 14%.
It is preferred that, each circle width of the shell liner is all 850mm.
Beneficial effects of the present invention are：
（1）The present invention combine closely large-scale overflowball mill input and output material end shell liner wear law, the degree of wear, abrasion speed
The difference of degree, summarizes and calculates the degree of wear, the rate of wear, designs the shell liner of different-thickness, matches somebody with somebody feed end shell liner
Put and realize stepped configuration.For large-scale grinding attachment, the domestic and international first Application technology has broken ball mill for many years
The mode of liner plate indifference tiling, is the innovation of grinding attachment technology, is the refreshing of grinding attachment preparation level, with important
Application value.
（2）For equipment manufacturer, the mode of staged configuration liner plate can be used as the design of large-sized grinder from now on, manufacture
With the foundation of Optimal improvements, the overall creative and advance of the kind equipment is remarkably improved.
（3）Liner plate thickness and the degree of wear, the perfect adaptation of the rate of wear, preferably realize that input and output material end shell liner is same
Equivalent life.
（4）Shell liner is stepped with postponing, and the circulation for slurry from feed end to discharge end is more smooth, without hindrance, enters
The rational ladder discrepancy in elevation of discharge end shell liner, preferably realizes the smooth ore discharge of slurry.
（5）The present invention is ingenious in design, implements simple, fully extension feed end shell liner service life, has prevented charging
Hold the maintenance of shell liner to change the frequency, reduction repair time and maintenance workload, improve the time of effectively driving, realize treating capacity
With economic benefit largest optimization, it is ensured that the safe and stable operation of large-scale overflowball mill cylinder.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As described in Figure 1, it is a kind of overflowball mills of Φ 5500 × 8500, the cylinder of the overflowball mills of Φ 5500 × 8500
It is shell liner 3 in body 1, cylinder 1 is built with milling medium 2, the shell liner 3 being provided with the cylinder 1, the cylinder 1
Feed end shell liner 3 is step type, the stepped shell liner 3 as shown in figure 3, the respectively circle of first lap 4, second 5, the
The circle 8 of the 6, the 4th circle of three circles the 7, the 5th and discharge end 9, the thickness of each circle are all identical, are all 850mm, wherein first lap 4 and second
Enclose 5 thickness identical, the 3rd circle 6 is identical with the 4th 7 thickness of circle, and the 5th circle 8 is identical with the thickness of discharge end 9, and first lap is 89.6mm,
3rd circle is 79.8mm, and the 5th circle is 70mm.
In 5500 × 8500 overflowball mills of Φ in using the present invention, the He of first lap 4 in the shell liner 3 in cylinder 1
The wear liner speed and degree of second circle 5 are the most serious, can only use 18 months, and the rate of wear is than the 5th circle 8 fast 25%, the
Three circles 6 and the 4th 7 rates of wear of circle and degree are more serious, and the rate of wear is faster by 15% than the 5th circle, the 5th circle 8 and discharge end 9
Liner plate is almost uniform wear.So by the configuration mode of the shell liner 3 of the overflowball mills of Φ 5500 × 8500 by such as Fig. 2
Shown horizontal arrangement is processed as stepped configuration as described in Figure 3, makes the life-span of feed end shell liner 3 by that can only use 18
Bring up within individual month 24-27 months, fully achieve the same of feed end shell liner life-span and 24 months shell liner life-spans of discharge end
Equivalent life.The replacing frequency of feed end shell liner is reduced, the sexual cycleization that realizes a plan changes shell liner, reduces the repair time
And maintenance workload, improve large-scale overflowball mill and effectively drive the time, realize Grinding procedure milling capacity and economic benefit
Largest optimization, it is ensured that the safe and stable operation of large-scale overflowball mill cylinder, it is ensured that the energy-efficient operation of large-size ball mill.
