Abstract

The invention relates to a three-separation type high-fineness powder grinding process. The three-separation type high-fineness powder grinding process is characterized by comprising a three-separation type vertical mill; a raw material inlet, a lifting material inlet, a fine powder outlet, a medium crude powder outlet and a mixed powder outlet are formed in the three-separation type vertical mill, wherein the medium crude powder outlet is connected with a ball mill; an outlet of the ball mill is connected with the lifting material inlet; the mixed powder outlet is connected with a lifter A; an outlet of the lifter is connected with the lifting material inlet. The three-separation type high-fineness powder grinding process has the beneficial effects that firstly, a powder concentrator and a vertical mill device are combined, so that the space is saved; most importantly, a device for sorting medium crude powder and crude powder is additionally arranged in the three-separation vertical mill, so that the medium crude powder and the crude powder can be effectively sorted by winnowing, thereby further providing different subsequent processing means and achieving the advantages of saving equipment, reducing cost and reducing energy consumption.

Description

Three separate type fine-grinding techniques
Technical field
The present invention relates to a kind of fine-grinding technique, be applicable to grind high thin material, be particularly useful for two closed-circuit grindings and produce cement, is a kind of novel fraction grinding process that requires high thin, high-strength, many kinds fusion material cement.
Background technology
Energy-saving and emission-reduction are targets that enterprise is pursued, and produce ultra-fine, high-strength, many kinds fusion material cement, are the demands of modern recycling economy and green building material.
In the fragmentation of material, grinding, account for the more than 90% of total power consumption.Common milling equipment is ball mill and vertical grinder, and 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 Now of vertical grinder is high at mill efficiency, power consumption is low, but its material grinding out in the form of sheets, strip, particle diameter shape is bad, and then causes the of low quality of cement.
In order to save the energy, ensure product quality simultaneously, the method that present stage generally adopts is that coarse fodder is worn into middle meal in advance through vertical grinder, sending into ball mill grinding is that fine powder is for selecting powder again, respectively establish one in vertical grinder, ball mill rear end and select powder equipment, so just make equipment investment large, take up an area more simultaneously, and operation link is loaded down with trivial details, in production, can bring some inconvenience.
Summary of the invention
The object of this invention is to provide a kind of three separate type fine-grinding techniques to make up the deficiency of prior art.
Technical scheme of the present invention is: three separate type fine-grinding techniques, is characterized in that:
Comprise three separation Vertical Mills, on three separation Vertical Mills, have material inlet, promote and expect that import, fine powder outlet, the outlet of middle meal, mixed powder export;
Middle meal outlet connects ball mill, and ball mill outlet connects the import of lifting material;
Mixed powder outlet connects elevator A, and lift outlet connects to promote expects import.
Optimize, between ball mill and the import of lifting material, have elevator B.
Beneficial effect of the present invention is: first, by selecting powder equipment and Vertical Mill equipment to combine, saved space; The more important thing is: the sorting unit that has increased middle meal and meal in three separation Vertical Mills, can effectively middle meal and meal be carried out to selection by winnowing, thereby the different following process means of providing of a step can be provided, reach saving equipment, reduce cost, lower the advantage of energy consumption.

Detailed description of the invention
Embodiment:
Initial material enters the interior meal mill of grinding assembly 26 from material inlet 25, and the material after meal mill contains fine powder, middle meal, meal.The advantage of this step is the advantage of utilizing Vertical Mill energy-conservation.
Because fine powder, middle meal, meal are in admixture, utilize effective method that three is separated: a small amount of fine powder directly becomes finished product, middle meal is sent into ball mill, meal pre-grinding again.
Wherein, the separation of fine powder is comparatively simple: air-flow, under blower negative pressure effect, enters in it through air inlet 24, the vane of grinding assembly 26, and is carrying fine powder upwards always, until enter product collector from finished product passage 8.The patent of the assorting room of above-mentioned fine powder before us 201320198571.1be described later in detail.
Technology before, for middle meal and meal, just cannot realize effective separation, can only be that mixture is all sent into ball mill, then powder concentrator is set after ball mill, is so in fact to make ball mill bear the pre-grinding task of part, has increased energy consumption; On the other hand, the powder concentrator that ball mill arranges below, has strengthened equipment investment and operating cost.
In this application, just can be effectively middle meal is realized and being separated with meal, thereby reach the object of setting, detailed process be as described below:
Middle meal after pre-grinding and the mixed powder of meal, enter in elevator A27 from the mixed powder outlet 23 of bottom, then be raised, enter in body 1 from promoting material import 100, after spreading grading wheel 4 enters spreading groove box 18, shed, falls.
When mixed powder enters into after the annular whereabouts mouth 101 of material of the taper being made up of reflection circle 12 and drip circle 10, continue to fall, due to the upright projection position on baffle liner 11 tops, outside the mouth 101 that falls, so whole mixed powders all can drop in baffle liner 11.
Herein, from the mouth 101 that falls to baffle liner 11 this part space, be exactly our sorting mouth 102.
Air-flow through grinding assembly 26 upwards, reflection circle 12 through spreader 13 and declivity layout is turned back, oblique blowing down is to the mixed powder (after adjusting parameter falling, blowing mode under oblique, be the best energy consumption of saving, select the best mode of powder effect), meal continues to fall, drop to the space, meal whereabouts 103 in baffle liner 11, then enter grinding assembly 26, carry out again pre-grinding; Middle meal is blown to the outer space of baffle liner 11, and because this space is larger, wind speed slows down rapidly, middle meal can not continue to raise up with the wind, and sedimentation is gone down, and falls into space, meal whereabouts 104, therefrom body 1 is left in meal outlet 7 again, delivers to ball mill 28 and carries out levigation mill.
The powder of ball mill 28 milleds, then by elevator B105, enter in body 1 from promoting material import 100, a large amount of fine powders that wherein contain are carried upwards and select by wind, and a small amount of middle fine powder falls again to be selected.
As seen from the above, this technique has in fact just been saved expense and the energy consumption of a powder concentrator.
