Description
Technical field
The present invention relates to the closed circuit wet screening system of ore dressing plant high pressure roller mill system, particularly a kind of high pressure roller mill.
Background technology
Along with the development of technique of preparing, increasing ore dressing plant have employed high pressure roller mill wet screening technique before ball mill ore grinding, but this technique also exists following problem in the production application of present stage: 1, during high pressure roller mill ribbon conveyer feed, material forms parabolic motion in dropping process, it is far away that coarsegrain material can be thrown, it is nearer that fine granularity material is then thrown, so just cause material segregation, make material can not feed high-pressure roller mill uniformly, damage is caused to equipment; 2, for reducing the impact that material segregation causes as far as possible, the expansion direction in the roller turn face of current high-pressure roller mill is parallel with the feeding direction of ribbon conveyer (roller axle of high-pressure roller mill is to vertical with ribbon conveyer feeding direction under storehouse), but this feed form makes the spacing of two high-pressure roller mills very large, because enough distances will be reserved for installing drive motors between the two, if the high-pressure roller mill of more than two will be arranged in same workshop, then very difficult complexity especially, can take and select factory place in a large number; 3, the spacing due to high-pressure roller mill is comparatively large, and corresponding each high pressure roller mill storage bin spacing also can be comparatively large, just creates gap, cannot use Lou mine car feed between adjacent feed bin; 4, wet screening sieve returns product due to moisture, can bond when itself and new feed feed same feed bin, have a strong impact on ore storage bin discharge.Therefore, existing high pressure roller mill wet screening system architecture configuration still needs to improve.
Summary of the invention
The object of the invention is to provide the closed circuit wet screening system of high pressure roller mill that a kind of structure is simple, configuration is reasonable, applicability is strong, reduce investment outlay, material segregation and consequent system takes up room greatly, high pressure roller mill storage bin spacing large and wet screening sieve returns the problem that product and new feed easily occur to bond when fundamentally solving existing screening system ribbon conveyer feed, realize configuring multiple stage high-pressure roller mill in a workshop, realize perpendicular to roller of high-pressure roller mill plane of rotation expansion direction feed.
Technical scheme of the present invention is:
The closed circuit wet screening system of a kind of high pressure roller mill, comprise high pressure roller mill crushing system, the high pressure roller mill product wet screening system be connected with high pressure roller mill crushing system and wet screening oversize retrieval system, it is characterized in that: described high pressure roller mill crushing system leaks mine car ribbon conveyer by carrying the band of new feed, be located at the high pressure roller mill storage bin below band leakage mine car ribbon conveyer, be located at ribbon conveyer under the storehouse below high pressure roller mill storage bin, be located at the batch mixing funnel of ribbon conveyer feed end under storehouse, be located at the high-pressure roller mill below batch mixing funnel and be located at the high pressure roller mill product ribbon conveyer composition below high-pressure roller mill, described high pressure roller mill product wet screening system is by the screening storage bin be located at below high pressure roller mill product ribbon conveyer feeding end, ribbon conveyer under screening storage bin, be located at the wet type reciprocating sieve below ribbon conveyer feed end under screening storage bin, under being located at the sieve below wet type reciprocating sieve, pump pond forms, described wet screening oversize retrieval system returns ribbon conveyer by what receive wet type reciprocating sieve oversize, be located at and return below ribbon conveyer feeding end and to leak mine car ribbon conveyer with the band that the band of the new feed of conveying leaks the conveying oversize that mine car ribbon conveyer is arranged side by side, the band being located at conveying oversize to leak below mine car ribbon conveyer and forms with the wet screening oversize storage bin that high pressure roller mill storage bin is arranged side by side, under described storehouse, ribbon conveyer extension cloth is placed in below wet screening oversize storage bin, and the roller axle of high-pressure roller mill is to parallel with ribbon conveyer feeding direction under storehouse.
The closed circuit wet screening system of above-mentioned high pressure roller mill, ribbon conveyer, batch mixing funnel, high-pressure roller mill one_to_one corresponding under described high pressure roller mill storage bin, wet screening oversize storage bin, storehouse, quantity is equal, is more than two or two, is arranged in same workshop.
The closed circuit wet screening system of above-mentioned high pressure roller mill, described batch mixing funnel is made up of the funnel with draw-in groove and the batch mixing plate inserted in this draw-in groove, and described draw-in groove is the U-shaped draw-in groove of raised type of horizontal direction, is located at hopper side walls position on the lower.
The closed circuit wet screening system of above-mentioned high pressure roller mill, between adjacent high pressure roller mill storage bin, between adjacent wet screening oversize storage bin, bulkhead top utilizes bridge plate to be connected, and bridge plate both sides are provided with pushes up level side wall with storehouse.
The invention has the beneficial effects as follows:
1, the batch mixing funnel of innovative design of the present invention can mix material, the material dropped on batch mixing plate can become liquidate with the material shape of normal descend, so just material can be mixed, in produced on-site, regulate the degree of mixedness of material by the insertion degree of manual adjustment batch mixing plate.In addition, this funnel effectively avoids ribbon conveyer to high pressure roller mill for material segregation during ore deposit, and the damage preventing material segregation to cause high-pressure roller mill, improves the operating efficiency of high-pressure roller mill;
2, due to material segregation problems when batch mixing funnel solves feed, then the present invention is achieved the roller axle of high-pressure roller mill to the arrangement form parallel with the direction of ribbon conveyer feed under storehouse, would not be intercepted by drive motors in the middle of such two high-pressure roller mills, decrease the distance between two high-pressure roller mills, the layout of multiple stage high-pressure roller mill in same workshop can be realized, device layout compact and reasonable, save Liao Xuan factory site area, decrease workshop building, save investment;
3, because the spacing of high-pressure roller mill reduces, the spacing of corresponding high pressure roller mill storage bin also just reduces, after utilizing bridge plate to connect between adjacent feed bin, when leaking mine car through bridge crossing plate, material can drop on bridge plate, when can automatically be slipped in feed bin after solid accumulation to certain altitude, avoid Lou mine car and fall outside storehouse through out-of-date material;
4, wet screening is returned product and feeds different feed bin respectively from new feed by the present invention, although wet screening returns product with moisture, but not containing mud, and granularity can not bond greatly, but containing a large amount of fine particle powder-form material in new feed, these two kinds of materials feed same feed bin and will bond, and these two kinds of materials are fed the method for different feed bin by the present invention respectively, avoid the bonding of material, prevent the blocking of ore storage bin.
