The utility model discloses an adopting the abrasive rubber material or taking metal framework rubber, increase of service life reduces and changes the number of times, and it is nimble convenient to change, and the dismouting maintenance is easy, saves the change time, reduces the equipment input cost, reduces intensity of labour, improves the mill rate of utilization, is applied to in mine equipment technical field.
Description
Technical field
The utility model relates to a kind of large-size ball mill Split type screening device in mining equiment technical field.
Background technology
At present, bargh is all faced with the problem reducing producing cost, and mine industry enters the low ebb phase especially at present.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.
Go out material screen as a kind of high-effective classifying equipment, be widely used in ball mill grinding operation, even also have application in (partly) autogenous tumbling mill.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 overall discharging drum sieve to sieve ore pulp at discharge end mostly, and screen cloth many employings steel bar of discharging drum sieve is welded, service life is short, and whole discharging drum sieve must be removed place under repair in screen cloth blocking or when damaging or change, not only replacing construction is long, labour intensity is large, and the discharging drum sieve removed can not reuse, and causes very large waste.The successful Application of the utility model on large-size ball mill, not only reduces maintain and replace cost, reduces labour intensity, saves replacing construction, and effectively extends out the service life of material screen, reduces and changes number of times, improves grinding machine utilization rate.Therefore, develop a kind of large-size ball mill Split type screening device 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 drum sieve after discharging drum sieve screen cloth blocks or damages; a kind of large-size ball mill Split type screening device is provided; this discharging sifter device has automatic discharge screening function; stop larger particles and enter next process; protection next process unit, goes out the spiral bar of material screen, sieve plate is changed flexibly and easily, removes and installs simple.
The purpose of this utility model is achieved in that a kind of large-size ball mill Split type screening device, comprise U-shaped part, sieve plate, discharging screen frame (unit), press strip, stud in quill shaft, discharging lining, spiral bar, discharging screen frame (unit), quill shaft is installed on discharging end of ball mill side, discharging screen frame (unit) is connected with discharging lining by high-strength bolt, sieve plate is fixed on discharging screen frame (unit) by the stud carried by press strip, and discharging screen frame (unit) inside spin muscle is fixed by U-shaped part in bolt and discharging screen frame (unit);
Described dismountable spiral bar, sieve plate, press strip material are pure abrasive rubber or band metallic framework rubber;
Described spiral bar, sieve plate, press strip are designed to several; Sieve plate slit design is 6-12mm.
Main points of the present utility model are its structure.Its operation principle is, a kind of large-size ball mill Split type screening structure, and rotarily drive out material screen by ball mill and rotate, ore pulp enters out material screen by quill shaft and lining, and the sieve plate that the mineral aggregate being less than 6mm passes through material screen enters next procedure; Be greater than the mineral aggregate of 6mm under the thrust going out material screen spiral bar, discharge outside grinder system, return a upper procedure by belt feeder, again carry out crushing grinding, again enter out material screen by quill shaft and lining and sieve.It is running stores that grinding machine goes out material screen, and the utility model designs for large-sized grinder, goes out material screen spiral bar and sieve plate all can be changed separately, and every part weight is within 25kg, and it is convenient, simple to operate to change, and shortens consumable accessory replacing construction, reduces labour intensity; Discharging screen frame (unit) can reuse, and reduces replacement cost; Equipment investment is few, and versatility is good.
The spiral drawing mechanism of a kind of large-size ball mill split compared with prior art, has automatic discharge screening function, stops larger particles and enter next process, protection next process unit, adopt abrasive rubber material or band metallic framework rubber, increase the service life, reduce and change number of times; Change flexible, dismounting maintenance easily, saves replacing construction, reduces equipment investment cost; Spiral bar and sieve plate detachable, when ore pulp enters out material screen, different to the plate wear degree of zones of different, when in one or a region during damages of screen deck, do not need to whole go out material screen change, only need to change sieve plate in this sieve plate or this region, raise the efficiency, reduce operating cost, window screen size is little, convenient processing, and versatility is good, discharging sieve structure simple and durable, remove and install conveniently, shorten replacing construction, reduce labour intensity, improve the advantages such as grinding machine utilization rate, 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.
Detailed description of the invention
With reference to accompanying drawing, a kind of large-size ball mill Split type screening device, comprise U-shaped part 4, sieve plate 5, discharging screen frame (unit) 6, press strip 7, stud 8 in quill shaft 1, discharging lining 2, spiral bar 3, discharging screen frame (unit), quill shaft 1 is installed on discharging end of ball mill side, discharging screen frame (unit) 6 is connected with discharging lining 2 by high-strength bolt, sieve plate 5 is fixed on discharging screen frame (unit) 6 by the stud 8 carried by press strip 7, and discharging screen frame (unit) 6 inside spin muscle 3 is fixed by U-shaped part in bolt and discharging screen frame (unit) 4.
Described dismountable spiral bar 3, sieve plate 5, press strip 7 material are pure abrasive rubber or band metallic framework rubber.
Described spiral bar 3, sieve plate 5, press strip 7 are designed to several; Sieve plate 5 slit design is 6-12mm.
The utility model is described in further detail below in conjunction with embodiment:
When ore pulp enters out material screen, different to the plate wear degree of zones of different, when in one or a region during damages of screen deck, do not need to whole go out material screen change, only need to change sieve plate in this sieve plate or this region, raise the efficiency, reduce operating cost; Extend service life, reduce and change number of times; Window screen size is little, convenient processing, and versatility is good; Discharging sieve structure simple and durable, removes and installs conveniently, shortens replacing construction, reduce labour intensity, improve grinding machine utilization rate.
