Description
Technical field
The present invention relates to a kind of respective grinding process at times, are suitable for grinding, grind multi items material, and especially suitable one
Kind requires the novel respective grinding process of high thin, high-strength, high-performance, multi items.
Background technique
Energy-saving and emission-reduction are the targets that enterprise is pursued.Produce dominance energy, high-strength, multi items blend the high-grade cement and work of material
Industry slag micro mist, building castoff collection feed powder, are the demands of modern circular economy and green building material.Country's cement industry is big absolutely at present
Majority produces cement using " combined grinding " technique, and this technique production cement has process flow simple, still, due to cement
Clinker, the various grindabilities for blending material are widely different, and causing clinker to cross grinding causes concrete cracking, slag be not levigate to lead to mine
Slag micro mist intensity plays undesirable.
In recent years occur respective grinding process production cement, such as 201120483623.0 producing cement by separated grinding in the market
System, this separate compiling cement production process, be divided into the grindability of material two classes carry out separate compiling, can make not
Grinding fineness with the material of grindability reaches rational state.But cannot still give full play to clinker, it is various blend material it is useful
Production size grading is reasonable, power consumption is minimum high-performance cement and industrial slag micro mist, building castoff collection feed powder is not achieved in characteristic
It is required that.
The applicant has applied for patent of invention: three separate type fine-grinding techniques on April 29th, 2014
(201410175663.7), it is desirable to provide a kind of energy-saving grinding process, on this basis, our expansions have studied subsequent
Application technology is allowed to be more suitable in actual production process.
Summary of the invention
The deficiency of the prior art is made up the object of the present invention is to provide a kind of respective grinding process at times.
The technical scheme is that powder equipment, three separation choosings are selected in a kind of respective grinding process at times, including three separation
Powder equipment includes Vertical Mill, ball mill and elevator, it is characterized in that:
More than two raw material stores are provided with, the material of raw material store enters Vertical Mill by raw material elevator；Ball milling
It is connected to out after machine and grinds elevator, ground lift outlet out and be connected to grinding switching valve, the road A and the road B are divided into after grinding switching valve；
The discharging of the road A returns to Vertical Mill；The discharging of the road B is sent to delivery chute by filler elevator；
Delivery chute is connected to 2 or more warehouse for finished products, has product to cut between each warehouse for finished product and delivery chute and changes valve.
Further optimization: the product outlet of Vertical Mill is connected to collector, and the outlet of collector connects filler elevator.
The beneficial effects of the present invention are: grinding system includes three separation sorting Vertical Mills, high thin ball mill, elevator, is closed
Reason utilizes change-over switch, grinds the material of different requirements at times, only can complete closed circuit pre- grinding with a set of milling equipment
With closed circuit high thin whole grinding, the high thin whole grinding of open circuit；Kind is divided to be melted into material grinding, batching, mixing at times more
Kind building material product.The production high-performance cement that size grading is reasonable, power consumption is low and various industrial slag micro mists, building castoff gather materials
Powder has given full play to clinker, the various characteristics for blending material in concrete.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
Embodiment:
In figure: 1 being raw material store, 2 be weigher, 3 be belt conveyer, 4 be raw material elevator, and 6 be middle coarse powder
Outlet, 7 be discharge port, and 8 be the product outlet of Vertical Mill, and 9 be Vertical Mill, and 10 be ball mill, and 11 be to grind elevator out, and 12 be to collect
Device, 13 grinding switching valves, 14 be filler elevator, and 15 be that product section changes valve, and 16 be warehouse for finished product, and 17 be delivery chute.
Three kinds of grinding modes:
Closed circuit pre- grinding: various materials in raw material store 1 are according to the demand of product, through weigher 2, belt conveyer 3
By raw material elevator 4 promoted convey, into the separating chamber of Vertical Mill 9 in sorted, fall on quilt in Vertical Mill 9 under coarse grain diameter material
Grinding；Material after grinding is discharged from discharge port 7, and the material of mixing belt conveyer 3 is conveyed by raw material elevator 4 together
It returns and is sorted again in the separating chamber of Vertical Mill 9, constitute closed circuit pre- grinding.
Closed circuit end grinding: middle coarse powder material enters in ball mill 10 from the middle coarse powder of Vertical Mill 9 outlet 6 to be ground, after grinding
Material is gone out the road A of mill elevator 11, grinding switching valve 13 and enters in the separating chamber of Vertical Mill 9 to be sorted again, coarse grain diameter material
It falls after rise in Vertical Mill 9 and refaces, grinding in middle coarse powder material goal grinding machine 10, qualified product is with negative pressure gas flow from the product outlet 8 of Vertical Mill 9
It is collected into collector 12, enters finished product system through filler elevator 14, constitute closed circuit whole grinding.
The whole grinding of open circuit: the powder in ball mill 10 after grinding promotes conveying through grinding switching valve 13 by going out to grind elevator 11
The road B, filler elevator 14 be directly entered finished product system, constitute whole grinding of opening a way.
The different finished products of different periods are cut by delivery chute 17, product to be changed valve 15 to enter different finished products 16 spare.
This technique only needs a set of milling equipment just to complete closed circuit pre- grinding and closed circuit high thin whole grinding, the high thin whole grinding of open circuit
A variety of grinding processes, pre- grinding, the simple process of whole grinding is convenient, low energy consumption；Closed circuit high thin whole grinding has size controlling
Accurately, product cut size gradation high and steep feature on foot, 10 μm~20 μm grains are especially big through material ratio, and high thin whole grinding of opening a way has partial size
It is reasonably distributed, is suitable for that clinker grinding powder and high activity multi items refer and synthesize material.
