Abstract
The utility model relates to a three-separation sorting vertical mill which comprises a lower powder milling assembly and an upper powder sorting assembly, wherein a gas material channel is arranged between the powder milling assembly and the powder sorting assembly; a fine powder outlet, a medium coarse powder outlet, a mixed powder outlet, a raw material inlet and a lifting material inlet are formed in the vertical mill; in the space of the vertical mill, a ring-shaped material falling hole is formed between a reflection ring and a dripping ring; a diversion ring is arranged in the space below the falling hole; a sorting hole is formed between the upper part of the diversion ring and the falling hole; a coarse powder falling space is formed in the inner side of the diversion ring; a medium coarse powder falling space is formed in the outer side of the diversion ring. The three-separation sorting vertical mill has the beneficial effect that the powder sorting equipment and the vertical mill equipment are combined so that the space is saved; more importantly, the sorting devices for medium coarse powder and coarse powder are additionally arranged in the combined equipment, so that the medium coarse powder and the coarse powder can be sorted effectively, different subsequent processing means can be further provided and then the aims of saving equipment, decreasing cost and reducing energy consumption are achieved.
Description
Technical field
The utility model relates to a kind of sorting Vertical Mill, is applicable to grind the classification milling equipment of high thin material.Being particularly useful in a kind of two closed-circuit grinding cement production process, is a kind of novel classification milling equipment 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 purpose of this utility model is to provide a kind of three and separates sorting Vertical Mill to make up the deficiency of prior art.
The technical solution of the utility model is: three separate sorting Vertical Mills, and what comprise the grinding assembly of bottom and top selects powder assembly, it is characterized in that:
Grinding assembly and select and have gas material passage between powder assembly;
On Vertical Mill, there are fine powder outlet, the outlet of middle meal, mixed powder outlet and material inlet, the import of lifting material;
In Vertical Mill space, between reflection circle and drip circle, form the annular whereabouts mouth of material; There is baffle liner in space under the mouth of whereabouts, between baffle liner top and whereabouts mouth, forms sorting mouth;
The inner side of baffle liner is space, meal whereabouts, and baffle liner outside is space, middle meal whereabouts.
Optimize, the upright projection position on baffle liner top is positioned at outside mouth.
Optimize, reflection circle, for up-small and down-big, becomes declivity to arrange, in reflection circle, has spreader.
Effect of the present utility model 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 unit equipment, 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, is exactly the object of application, is also creationary embodiment.
Wherein, the separation of fine powder: 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 201320198571.1 of the assorting room of above-mentioned fine powder before us is 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 effectively middle meal be realized and being separated with meal, detailed process be as described below:
Middle meal after pre-grinding and the mixed powder of meal, fall in elevator 27 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 compound 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, because the upright projection position on baffle liner 11 tops is positioned at outside mouth 101, 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 closed material powder (after adjusting parameter to what fall, 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 regrind mill.
The powder of ball mill 28 milleds, then expect that from entering to promote import 100 enters in body 1, 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, due to the machine integrated three kinds of material outlets, expense and the energy consumption of in fact just having saved a powder concentrator.
