Description

Separate compiling equipment at times

Technical field

This utility model is related to a kind of separate compiling equipment at times, it is adaptable to grinding, grinding multi items material, especially fits With a kind of new respective grinding process for having high demands thin, high-strength, high-performance, multi items.

Background technology

Energy-saving and emission-reduction are the targets that enterprise is pursued.Production dominance energy, high-strength, multi items blend the high-grade cement and work of material Industry slag micropowder, building castoff collection feed powder, are the demands of modern recycling economy and green building material.Country's cement industry is big absolutely at present It is most to adopt " combined grinding " technique productions cement, this technique productions cement to have technological process simple, but, due to cement Grog, various blending materials grindability it is widely different, causing grog to cross grinding causes that concrete cracking, slag be not levigate to cause ore deposit Slag micropowder intensity plays undesirable.

In recent years respective grinding process production cement, such as 201120483623.0 producing cement by separated grinding are occurred in that on market System, this separate compiling cement production process is to be divided into two classes with the grindability of material to carry out separate compiling, can make not Rational state is reached with the grinding fineness of the material of grindability.But, can not still give full play to grog, various blending materials it is useful Characteristic, does not reach the production high-performance cement that size grading is reasonable, power consumption is minimum and industrial slag micropowder, building castoff collection feed powder Require.

The applicant has applied for utility model patent on April 29th, 2014：Three separate type fine-grinding techniques (201410175663.7) a kind of, it is desirable to provide energy-saving grinding process, on this basis, our expansions have studied follow-up Application technology, is allowed to be more suitable in actual production process.

Utility model content

The purpose of this utility model is to provide a kind of separate compiling equipment at times to make up the deficiency of prior art.

The technical solution of the utility model is：A kind of separate compiling equipment at times, including three separate and select powder equipment, three points From selecting powder equipment to include Vertical Mill, ball mill and elevator, it is characterized in that：

Plural raw material store is provided with, raw material elevator between raw material store and Vertical Mill, is provided with；Ball mill After be connected to out mill elevator, go out to grind lift outlet and be provided with grinding switching valve, after grinding switching valve, be divided into A roads and B roads；

A roads connect Vertical Mill；B roads connect filler elevator, and filler elevator is followed by delivery chute；

Delivery chute is connected to the warehouse for finished product of more than 2, has product to cut and change valve between each warehouse for finished product and delivery chute.

It is further to optimize：The product outlet of Vertical Mill is connected to catcher, and the outlet of catcher connects filler elevator.

The beneficial effects of the utility model are：Grinding system includes three separation sorting Vertical Mill, high thin ball mill, is lifted Machine, reasonably using permutator, grinds the material of different requirements at times, only can just complete closed circuit pre- with a set of milling equipment Grinding and closed circuit high thin end grinding, the high thin end grinding of open circuit；At times graded kind by material grinding, batching, mixing homogenizing Into various building material products.The production high-performance cement that size grading is reasonable, power consumption is low and various industrial slag micropowders, building castoff Collection feed powder, has given full play to the characteristic of grog, various blending materials in concrete.

Description of the drawings

Fig. 1 is structural representation of the present utility model.

Specific embodiment

Embodiment：

In figure：1 is raw material store, 2 is weigher, 3 is belt conveyer, and 4 is raw material elevator, and 6 is middle coarse powder Outlet, 7 is discharging opening, and 8 is the product outlet of Vertical Mill, and 9 is Vertical Mill, and 10 is ball mill, and 11 is to grind elevator, and 12 is to collect Device, 13 grinding switching valves, 14 is filler elevator, and 15 is that product section changes valve, and 16 is warehouse for finished product, and 17 is delivery chute.

Three kinds of grinding modes：

Closed circuit pre- grinding：Demand of the various materials in raw material store 1 according to product, Jing weighers 2, belt conveyer 3 Conveying is lifted by raw material elevator 4, is sorted in the separating chamber of Vertical Mill 9, under the material of coarse grain footpath, is fallen quilt in Vertical Mill 9 Grinding；Material after grinding is discharged from discharging opening 7, and the material for mixing belt conveyer 3 is conveyed by raw material elevator 4 together Sorted in the separating chamber for returning Vertical Mill 9 again, constituted closed circuit pre- grinding.

Closed circuit whole grinding：Middle coarse powder material enters grinding in ball mill 10 from the middle coarse powder outlet 6 of Vertical Mill 9, after grinding Material Jing goes out to grind elevator 11, the A roads of grinding switching valve 13 are sorted again in the separating chamber of Vertical Mill 9, coarse grain footpath material Fall after rise in Vertical Mill 9 and refaces, middle coarse powder material enters grinding in ball mill 10, certified products are with negative-pressure air-flow from the product outlet 8 of Vertical Mill 9 It is collected into catcher 12, Jing filler elevators 14 enter finished product system, constitutes closed circuit whole grinding.

The whole grinding of open circuit：Powder in ball mill 10 after grinding lifts conveying Jing grindings switching valve 13 by going out to grind elevator 11 B roads, filler elevator 14 be directly entered finished product system, constitute the whole grinding of open circuit.

The different finished products of different periods are cut by delivery chute 17, product and change valve 15 to enter into different finished products 16 standby.

This technique only needs a set of milling equipment just to complete closed circuit pre- grinding and closed circuit high thin end grinding, the high thin end grinding of open circuit Various grinding processes, pre- grinding, whole grinding process is simple is convenient, energy consumption is low, closed circuit high thin end grinding has particle diameter distribution Precise control, product cut size level with it is on foot high and steep the characteristics of, 10 μm～20 μm grain Jing material ratios are especially big, and the high thin end grinding of open circuit has Rationally, suitable clinker grinding powder and high activity multi items refer and synthesize material to particle diameter distribution.
