Description
Technical field
The present invention relates to ore dressing plant high pressure roller mill system, particularly a kind of closed circuit wet screening system of high pressure roller mill.
Background technology
With continuing to develop for technique of preparing, it is wet that increasing ore dressing plant employs high pressure roller mill before ball mill ore grinding
Formula sieving technology, however this technique be there are problems that in production application at this stage it is as follows：1st, high pressure roller mill band
When formula conveyer is fed, material forms parabolic motion in dropping process, and big granularity material can be thrown farther out, and fine granularity thing
It is relatively near that material is then thrown, and thus causes material segregation so that material can not uniformly feed high-pressure roller mill, and equipment is made
Into damage；2nd, be to reduce the influence that causes of material segregation as far as possible, the expansion direction in the roller turn face of current high-pressure roller mill with
The feeding direction of ribbon conveyer is parallel（The roller of high-pressure roller mill is axially vertical with ribbon conveyer feeding direction under storehouse）, but
This feed form causes that two spacing of high-pressure roller mill are very big, because to be reserved to install motor between the two
Enough distances, if same workshop will arrange the high-pressure roller mill of more than two, even more extremely difficult complexity can take big
Liang Xuan factories place；3rd, because the spacing of high-pressure roller mill is larger, corresponding each high pressure roller mill storage bin spacing also can be larger, phase
Gap is just generated between adjacent feed bin, it is impossible to be fed using leakage mine car；4th, product is returned to due to aqueous on wet screening sieve, it gives with newly
Material can be bonded when feeding same feed bin, have a strong impact on ore storage bin discharge.Therefore, existing high pressure roller mill wet screening system knot
Structure configuration still needs to improve.
The content of the invention
The invention aims to the high pressure roller for providing a kind of simple structure, configure reasonable, strong applicability, reduce investment outlay
Closed circuit wet screening system is ground, material segregation is fundamentally solved when existing screening system ribbon conveyer is fed and is thus produced
System take up room greatly, high pressure roller mill storage bin spacing is big and wet screening sieve on return to product and new feed is easily bonded asks
Topic, is realized configuring many high-pressure roller mills in a workshop, and realization is given perpendicular to roller of high-pressure roller mill plane of rotation expansion direction
Material.
The technical scheme is that：
A kind of closed circuit wet screening system of high pressure roller mill, including high pressure roller mill crushing system and high pressure roller mill crushing system
Connected high pressure roller mill product wet screening system and wet screening oversize return system, it is characterised in that：The high pressure
Roller grinds band leakage mine car ribbon conveyer of the crushing system by the new feed of conveying, the high pressure below band leakage mine car ribbon conveyer
Roller mill storage bin, ribbon conveyer, the ribbon conveyer feed end under storehouse under the storehouse below high pressure roller mill storage bin
Batch mixing funnel, the high-pressure roller mill below batch mixing funnel and the high pressure roller mill product belt below high-pressure roller mill
Conveyer is constituted, and the high pressure roller mill product wet screening system is by under high pressure roller mill product ribbon conveyer feeding end
Ribbon conveyer, the ribbon conveyer feed end lower section under screening storage bin under screening storage bin, the screening storage bin of side
Wet type reciprocating sieve, under the sieve below wet type reciprocating sieve pump pond composition, the wet screening oversize return system by
Receive wet type reciprocating sieve oversize return ribbon conveyer, located at return ribbon conveyer feeding end lower section and with conveying
The band leakage mine car ribbon conveyer of the conveying oversize that the band leakage mine car ribbon conveyer of new feed is arranged side by side, located at conveying
The band leakage mine car ribbon conveyer lower section of oversize and the wet screening oversize storing being arranged side by side with high pressure roller mill storage bin
Storehouse constitute, under the storehouse ribbon conveyer be disposed to extend in wet screening oversize storage bin lower section, and high-pressure roller mill roller
It is axially parallel with ribbon conveyer feeding direction under storehouse.
The closed circuit wet screening system of above-mentioned high pressure roller mill, the high pressure roller mill storage bin, wet screening oversize storage bin,
Ribbon conveyer, batch mixing funnel, high-pressure roller mill are corresponded under storehouse, and quantity is equal, is two or more than two, is arranged in
In same workshop.
The closed circuit wet screening system of above-mentioned high pressure roller mill, the batch mixing funnel is by the funnel with draw-in groove and inserts the draw-in groove
Interior batch mixing plate composition, the draw-in groove is the raised type U-shaped card slot of horizontal direction, located at hopper side walls position on the lower.
The closed circuit wet screening system of above-mentioned high pressure roller mill, the wet screening sieve between adjacent high pressure roller mill storage bin, adjacent
Bulkhead top is connected using bridge plate between upper product storage bin, and bridge plate both sides are provided with and the level side wall of silo roof.
The beneficial effects of the invention are as follows：
1st, the batch mixing funnel of innovative design of the present invention can be mixed to material, and the material fallen on batch mixing plate is understood and normal
The material shape of whereabouts can thus mix material into liquidating, can be by the insertion of manual adjustment batch mixing plate in produced on-site
Spend to adjust the degree of mixedness of material.In addition, the funnel effectively avoid ribbon conveyer to high pressure roller mill supply ore deposit when thing
Material segregation, it is therefore prevented that the damage that material segregation is caused to high-pressure roller mill, improves the operating efficiency of high-pressure roller mill；
2nd, material segregation problems during feed are solved due to batch mixing funnel, then the present invention is achieved high-pressure roller mill
Roller arrangement form axially parallel with the direction that ribbon conveyer under storehouse is fed, would not in the middle of such two high-pressure roller mills
Intercepted by motor, reduce the distance between two high-pressure roller mills, it is possible to achieve many high-pressure roller mills in same workshop
Arrangement, device layout compact and reasonable saves Liao Xuan factories site area, reduces workshop building, saves investment；
3rd, because the spacing of high-pressure roller mill reduces, the spacing of corresponding high pressure roller mill storage bin is also reduced by, adjacent material
After being connected using bridge plate between storehouse, when mine car is leaked through bridge crossing plate, material can fall on bridge plate, after solid accumulation is to certain altitude
Can be slipped in feed bin automatically, it is to avoid material is fallen outside storehouse when leakage mine car passes through；
4th, wet screening is returned to product and feeds different feed bins respectively from new feed by the present invention, and wet screening returns to product although with water
Point, but mud is free from, and granularity will not be bonded greatly, but contain a large amount of fine particle powder-form materials in new feed, both
Material feeds same feed bin and will bond, the method that both materials are fed the present invention different feed bins respectively, it is to avoid
The bonding of material, it is therefore prevented that the blocking of ore storage bin.
