The utility model discloses a detachable welt and spiral muscle adopt the abrasive rubber material or take metal framework rubber, and increase of service life reduces and changes the number of times, it is nimble convenient to change, and the dismouting maintenance is easy, saves the change time, reduces the equipment input cost, is applied to in mine equipment technical field.
Description
Technical field
The utility model relates to the spiral drawing mechanism of a kind of large-size ball mill split in mining equiment technical field.
Background technology
At present, bargh is all faced with the problem reducing producing cost, and especially mine industry enters the low ebb phase.Due to the growth of energy expenditure, the grade of ore declines, and is an important topic by reduction cost of investment and producing cost.The mentality of designing of current world mine industry all adopts fragmentation---semi-autogenous mill---ball mill, simplification of flowsheet greatly, reduces cost of investment, decreases consumable accessory running stores quantity and kind, thus reduces producing cost.
Along with the increasing of ball mill specification, grinding machine treating capacity is increasing, and when maintenance down changes consumable accessory running stores, production loss is also larger.Therefore change consumable accessory quickly and easily and just seem particularly important.Traditional ball mill adopts monoblock cast discharging lining mostly, adopt cast steel or cast iron quality, service life is short, and whole discharging lining must be removed place under repair when damaging or change, not only replacing construction is long, labour intensity is large, and the discharging lining removed can not reuse, and causes very large waste.Therefore, develop the spiral drawing mechanism of a kind of large-size ball mill split is new problem anxious to be resolved always.
Summary of the invention
The purpose of this utility model is, for solving the problem must changing whole discharging lining after discharging lining damages, there is provided a kind of large-size ball mill split spiral drawing mechanism, this discharging structure has automatic returning charge function, stop larger particles and steel ball enters next process, improve grinding efficiency, protection next process unit, the liner plate of discharging lining, spiral bar is changed flexible, remove and install simple, not only reduce maintain and replace cost, reduce labour intensity, save replacing construction, and effectively extend the service life of discharging lining, reduce and change number of times, improve grinding machine utilization rate.
The purpose of this utility model is achieved in that the spiral drawing mechanism of a kind of large-size ball mill split, comprise end cover lining board for ball mill, crusher discharge end cover, quill shaft, wedge block, lining frame, liner plate, spiral bar, fixture, crusher discharge end cover is fixed in the left part of quill shaft, at crusher discharge end cover internal fixtion end cover lining board for ball mill, lining frame is connected with quill shaft by high-strength bolt, by wedge block and quill shaft fastening; Spiral bar is connected with lining frame by fixture, is pressed on by liner plate in lining frame;
The spiral drawing mechanism of a kind of large-size ball mill split, comprise wedge block, lining frame, liner plate, spiral bar, fixture, lining frame is connected with quill shaft by high-strength bolt, by wedge block and quill shaft fastening; Spiral bar is connected with lining frame by fixture, is pressed on by liner plate in lining frame;
Described dismountable liner plate, spiral bar material are pure abrasive rubber or band metallic framework rubber;
Described wedge block, liner plate, spiral bar are designed to several, and have versatility.
Main points of the present utility model are its structure.Its operation principle is, the spiral drawing mechanism of a kind of large-size ball mill split, discharging lining and ball mill common rotation, next procedure is entered by quill shaft and discharging lining after ore pulp grinds in ball mill barrel, discharging lining is made up of wedge block, lining frame, liner plate, spiral bar, fixture, and granule mineral aggregate relies on ore pulp overflow to enter next procedure by discharging lining; Bulk mineral aggregate and steel ball sink to bottom ore pulp due to the weight of itself, under the thrust of discharging lining spiral bar, return grinding mill barrel, again carry out crushing grinding, again enter next process by quill shaft and discharging lining.When ore pulp enters discharging lining, different with the spiral bar degree of wear to the liner plate of zones of different, when one or a field liner plate and spiral bar damage, do not need to change whole discharging lining, only need to change this liner plate and spiral bar or this field liner plate and spiral bar, raise the efficiency, reduce operating cost; Liner plate and spiral bar adopt abrasive rubber material or band metallic framework rubber, increase the service life, reduce and change number of times.
The spiral drawing mechanism of a kind of large-size ball mill split compared with prior art, has dismountable liner plate and spiral bar, adopts abrasive rubber material or band metallic framework rubber, increases the service life, reduce and change number of times; Change flexible, dismounting maintenance easily, saves replacing construction, reduces the advantages such as equipment investment cost, will be widely used in mining equiment technical field.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and enforcement, the utility model is described in detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the I portion enlarged drawing of Fig. 1.
Fig. 3 is II enlarged drawing of Fig. 1.
Detailed description of the invention
With reference to accompanying drawing, the spiral drawing mechanism of a kind of large-size ball mill split, comprise end cover lining board for ball mill 1, crusher discharge end cover 2, quill shaft 3, wedge block 4, lining frame 5, liner plate 6, spiral bar 7, fixture 8, crusher discharge end cover 2 is fixed in the left part of quill shaft 3, at crusher discharge end cover 2 internal fixtion end cover lining board for ball mill 1, lining frame 5 is connected with quill shaft 3 by high-strength bolt, fastening by wedge block 4 and quill shaft 3; Spiral bar 7 is connected with lining frame 5 by fixture 8, is pressed in lining frame 5 by liner plate 6.
Described dismountable liner plate 6, spiral bar 7 material are pure abrasive rubber or band metallic framework rubber.
Described wedge block 4, liner plate 6, spiral bar 7 are designed to several, and have versatility.
The utility model is described in further detail below in conjunction with embodiment:
When ore pulp enters discharging lining, different with spiral bar 7 degree of wear to the liner plate 6 of zones of different, when one or a field liner plate 6 and spiral bar 7 damage, do not need to change whole discharging lining, only need to change this liner plate 6 and spiral bar 7 or this field liner plate 6 and spiral bar 7, raise the efficiency, reduce operating cost; Liner plate 6 and spiral bar 7 adopt abrasive rubber material or band metallic framework rubber, extend service life, reduce and change number of times; Liner plate 6 and spiral bar 7 size little, convenient processing, versatility is good; Adopt the method for wedge block 4 tensioner, reduce between discharging lining and quill shaft bolt strained, strengthen reliability; Discharging bush structure simple and durable, removes and installs conveniently, shortens replacing construction, reduce labour intensity, improve grinding machine utilization rate.
