Abstract
The present invention relates to a kind of three separate type fine-grinding techniques, it is characterized in that: include three separate type Vertical Mills, three separation Vertical Mills have material inlet, promotes and expect that import, fine powder outlet, the outlet of middle coarse powder, mixed powder export；The outlet of middle coarse powder connects ball mill, and ball mill outlet connects lifting material import；Mixed powder outlet connects elevator A, and lift outlet connects to promote expects import.The beneficial effects of the present invention is: first, by selecting powder equipment and Vertical Mill equipment to be combined, saved space；The more important thing is: coarse powder and the sorting unit of coarse powder in adding in three separate Vertical Mill, effectively middle coarse powder and coarse powder can be carried out selecting crude drugs with winnower, it is thus possible to carry out a step provides different following process means, reach saving equipment, reduce cost, the advantage lowering energy consumption.
Description
Technical field
The present invention relates to a kind of fine-grinding technique, it is adaptable to grind high thin material, be particularly suited for double closing
Road grinding produces cement, is a kind of novel hierarchical grinding requiring that height is thin, high-strength, multi items blends material cement
Technique.
Background technology
Energy-saving and emission-reduction are the targets that enterprise is pursued, and produce ultra-fine, high-strength, multi items blending material cement, are existing
For recycling economy and the demand of green building material.
More than the 90% of total power consumption is accounted in broken, the grinding of material.Common milling equipment is ball mill
And vertical grinder, wherein ball mill efficiency is low, and power consumption is high, but it has a unrivaled advantage:
The particle diameter shape of ball mill grinding material is good, the feature that cement characteristics is good；And the advantage body of vertical grinder exists
Mill efficiency is high, and power consumption is low, but its material being ground in the form of sheets, strip, particle diameter shape is bad,
And then cause the of low quality of cement.
In order to save the energy, ensureing product quality, present stage commonly used method is through vertical by coarse fodder simultaneously
Middle coarse powder worn in advance by formula grinding machine, be re-fed into ball mill grinding be fine powder for selecting powder, simultaneously vertical grinder,
Ball mill rear end respectively sets one and selects powder equipment, thus makes equipment investment big, takes up an area more, Er Qiecao
Make link loaded down with trivial details, production can bring some inconvenience.
Summary of the invention
It is an object of the invention to provide a kind of three separate type fine-grinding techniques to make up the deficiency of prior art.
The technical scheme is that three separate type fine-grinding techniques, it is characterized in that:
Including three separation Vertical Mills, three separate have on Vertical Mills material inlet, promote material import, fine powder outlet,
The outlet of middle coarse powder, mixed powder outlet；
The outlet of middle coarse powder connects ball mill, and ball mill outlet connects lifting material import；
Mixed powder outlet connects elevator A, and lift outlet connects to promote expects import.
Optimize, between ball mill and lifting material import, have elevator B.
The beneficial effects of the present invention is: first, powder equipment and Vertical Mill equipment will be selected to be combined, save
Space；The more important thing is: coarse powder and the sorting unit of coarse powder in adding in three separate Vertical Mill, can have
Effect middle coarse powder and coarse powder are carried out selecting crude drugs with winnower, it is thus possible to carry out a step provides different following process means,
Reach saving equipment, reduce cost, the advantage lowering energy consumption.

Detailed description of the invention
Embodiment:
Initial material enters coarse powder mill in grinding assembly 26 from material inlet 25, and the material after coarse powder mill contains
Fine powder, middle coarse powder, coarse powder.The advantage of this step is the advantage utilizing Vertical Mill energy-conservation.
Owing to fine powder, middle coarse powder, coarse powder are in admixture, effective method to be utilized three to be separated:
A small amount of fine powder is directly becoming finished product, middle coarse powder sends into ball mill, the most pre-grinding of coarse powder.
Wherein, the separation of fine powder is relatively simple: air-flow is under blower negative pressure effect, through grinding assembly 26
Air inlet 24, vane enter in it, and carry fine powder all the way up, until entering into from product channel 8
Product catcher.The assorting room of above-mentioned fine powder patent in our prior201320198571.1Have detailed
Describe.
Technology before, for middle coarse powder and coarse powder, just cannot realize efficiently separating, and can only be by mixed
Compound all sends into ball mill, then arranges powder concentrator after ball mill, the most substantially makes ball mill hold
Carry on a shoulder pole part pre-grinding task, add energy consumption；On the other hand, the powder concentrator that ball mill is disposed behind,
Increase equipment investment and operating cost.
In this application, just can effectively realize separating by middle coarse powder and coarse powder, thus reach the purpose set,
Details are provided below:
Middle coarse powder after pre-grinding and the mixed powder of coarse powder, the mixed powder outlet 23 entrance elevator from bottom
In A27 more elevated, from promote material import 100 enter in body 1, enter through spreading grading wheel 4
Shed after entering spreading groove box 18, fallen.
When mixed powder enters into the whereabouts of the annular of the material of the taper being made up of reflection circle 12 and drip circle 10
After mouth 101, continue to fall, due to the upright projection position on baffle liner 11 top, setting in whereabouts mouth 101
Outside, so, whole mixed powders all can fall in baffle liner 11.
Herein, from whereabouts mouth 101 to this segment space of baffle liner 11, it is simply that our sorting mouth 102.
Air-flow through grinding assembly 26 upwards, rolled over by the reflection circle 12 arranged through spreader 13 and declivity
Returning, the mixed powder that blows to obliquely to fall (after adjusting parameter, blowing mode obliquely, is
Good energy efficient, selects the mode that powder effect is best), coarse powder continues to fall, and drops in baffle liner 11
Coarse powder droping space 103, enters back into grinding assembly 26, carries out the most pre-grinding；Middle coarse powder is blown to water conservancy diversion
The outer space of circle 11, owing to this space is relatively big, wind speed slows down rapidly, and middle coarse powder can not continue to go up with the wind
Raise, and settle, fall into middle coarse powder droping space 104, more therefrom body 1 is left in coarse powder outlet 7,
Deliver to ball mill 28 and carry out levigation mill.
The powder of ball mill 28 milled, then by elevator B105, enter body 1 from promoting material import 100
In, a large amount of fine powders wherein contained are carried by wind and upwards select, and a small amount of middle fine powder falls again to be selected.
As seen from the above, this technique substantially saves on expense and the energy consumption of a powder concentrator.
