Abstract
The utility model provides a liner plate of a ball mill. The inner surface of the liner plate adopts a double-wave-peak streamline structure; a perforating and lifting hole is vertically formed in the inner surface of the liner plate. The liner plate is simple in structure and convenient to mount; the double-wave-peak streamline structure is adopted, so that a steel ball and ore can form a reasonable transition together with the ripples of the liner plate during rotation; meanwhile, due to the double-ripple design, the defects of cracks and damage caused by stress concentration in production and use processes can be satisfactorily avoided, and the service life of the liner plate is prolonged.
Description
Technical field
The utility model relates to a kind of ball grinding machine lining board of new structure.
Background technology
Ball mill is exactly the production equipment of each large mine indispensability all the time, and its major spare part---ball grinding machine lining board belongs to consumable accessory, and each mine is quite large to its demand, and often because the replacing liner plate cycle is short, impact is produced, thereby has a strong impact on the production in mine.
General a set of liner plate can only be with 5-6 month, and it is large that liner plate workload is changed in each maintenance, and ore deposit amount is produced and brought adverse effect.
Summary of the invention
The purpose of this utility model is exactly in order to overcome above-mentioned the deficiencies in the prior art part, and a kind of ball grinding machine lining board is provided, and it can effectively solve the problem that liner plate wearability is lower, the replacement cycle is short.
The purpose of this utility model is achieved by the following technical measures: a kind of ball grinding machine lining board, described liner plate inner surface is dual waves streamline structure, on described liner plate inner surface, is vertically provided with tying up hole.
In technique scheme, described liner plate is provided with bolt hole.
The utility model ball mill lining plate structure is simple, convenient installation, adopt dual waves streamline structure, make steel ball and ore in rotary course can with the reasonable transition of liner plate ripple, simultaneously this dual damascene design can well avoid produce and use procedure in the concentrated and defects such as the crackle that causes, breakage of stress, thereby the service life that has strengthened liner plate.The ball grinding machine lining board of general domestic production can only be used about 5000 hours continuously, and the utility model liner plate can be used more than 7000 hours continuously, thereby significantly improves user's economic benefit, is highly suitable for using with ball mill as Deng Ge mine, Da Ye Iron Mine.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model ball grinding machine lining board.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the A-A sectional view of Fig. 1.
Wherein: 1. liner plate, 2. tying up hole, 3. bolt hole.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
As shown in Figure 1, 2, 3, the present embodiment provides a kind of ball grinding machine lining board, and described liner plate 1 inner surface is dual waves streamline structure.Described liner plate 1 is provided with bolt hole 3, for liner plate being fixed on to ball mill inwall by bolt.
In the above-described embodiments, described liner plate 1 inner surface is vertically provided with tying up hole 2, for convenient, liner plate 1 is sling and is installed in grinding mill barrel.
The ball grinding machine lining board that the present embodiment is produced adopts dual waves streamline structure, make steel ball and ore in rotary course can with the reasonable transition of liner plate ripple, simultaneously this dual damascene design can well avoid produce and use procedure in the concentrated and defects such as the crackle that causes, breakage of stress, thereby the service life that has strengthened liner plate.
Be below the assay of the present embodiment gained after the production and application of Da Ye Iron Mine:
2009.12 ends ore dressing stop production to overhaul; the present embodiment liner plate is installed to 10 and in feeding of ball mill end, 10 of common liner plates are also installed into ball mill simultaneously, the available machine time is on December 25th, 2009; be on June 23rd, 2010 downtime, approximately 3535 hours available machine times.After shutting down, producer and user have done a series of hardness, size, weight sampling test jointly.
Data statistics
1, hardness HRC comparison
Hardness is apparently higher than common liner plate.
2, weightless situation
3, with till may wear to the nut top of liner plate installation
Total available machine time: 3535 hours
Average abrasion thickness: 21.7mm, hour wear extent: 21.7 ÷ 3535=0.00613861mm
Remaining nut end face can be consumed time to casting thickness: 21 ÷ 0.00613861=3421 hour
Altogether should consume time; 3535+3421=6975 hour
From this commerical test situation analysis: the present embodiment liner plate can be used and be greater than 7000 hours.
From hardness and wear weight loss situation, relatively can find out that the present embodiment liner plate wearability is high, can significantly improve user's economic benefit, be suitable for each large mining ball grinding production and applications such as Da Ye Iron Mine, Jinshandian Iron Mine, Cheng Chao iron ore.
