As the embodiment of a modification of the present invention, described low wind speed nozzle ring sprays wind speed
It is not more than 30m/s, and its draught area is adjustable.
As the embodiment of a modification of the present invention, as shown in Fig. 2 according to grinding material
Characteristic carry out system enhancement, when equipment grinding raw material, may contain because it goes out in grind materials
There are bulk materials, export setting vibration type screening plant 13 in elevator 6, vibration type sieves
The outlet of device 13 coarse powder is connected with material charging aperture 2-2, the fine powder of vibration type screening plant 13
Outlet is connected with feeding-distribution device 7 charging aperture.Its operation principle is:Material exports from elevator 6
Flow out, and deliver to vibration type screening plant 13 and carry out vibrosieve, wherein coarse powder goes out from coarse powder
Mouth delivers to material charging aperture 2-2, is fed in Vertical Mill 2 together with the fresh material from proportioning station
Re-start grinding;Fine powder is then delivered to feeding-distribution device 7 and is carried out sub-material, and after sub-material, material is through first
Charging aperture 3-1 and second charging aperture 3-2 enter efficient cyclone 3 and are sorted.
As embodiments of the present invention improve, described first charging aperture 3-1 be set to three or
More than three, each charging aperture above the first material-strewing device circumferentially to being evenly arranged, to realize
The uniformity of the uniform and spreading of material.
Using the side from the first air inlet 2-1 and the second air inlet 3-4 air intake simultaneously in the present invention
Formula;Blow into hot blast at the first air inlet 2-1, hot blast is right through during falling material
Material is tentatively dried, it is to avoid material causes unfavorable shadow to lifting conveying equipment greatly due to moisture
Ring;Low wind speed nozzle ring 2-4 area is adjustable, controls air force according to practical operation situation,
Hot blast can be realized passes through air current spray nozzle circulation speed to be not more than 30m/s, so that the present invention is neutral
The SR of mill 2 can be greatly reduced compared with traditional interior circulation Vertical Mill 2;Efficient cyclone 3
The second material-strewing device bottom be provided with the second air inlet 3-4, this is partially into air-flow without too low
Wind speed nozzle ring 2-4, can reduce the speed at low wind speed nozzle ring 2-4 and lose with impulsive force,
Compared with all from the mode of the first air inlet 2-1 air intake, SR reduces further, should
Place air-flow can will in efficient cyclone 3 second material-strewing device dispersion after material in thin
Material is brought into sorting area and is sorted;Meanwhile, all of air intake is tangential air intake so that standing
Interior and separator interior the airflow field of mill 2 is more uniformly distributed.
Additionally, arranging cold blast sliding valve a at the first air inlet 2-1, set at the second air inlet 3-4
Put cold blast sliding valve b, can be adjusted by cold blast sliding valve and control the first air inlet 2-1 and the second air inlet
The pathogenic wind-warm of 3-4;When the moisture content of material entering Vertical Mill 2 is higher, make the first air inlet 2-1
Pathogenic wind-warm is higher than the second air inlet 3-4 pathogenic wind-warm, enhances the moisture drying function of material, it is to avoid because
The too high generation causing situations such as grinding effect is poor, conveying equipment blocks of moisture content of material;When
Enter Vertical Mill 2 moisture content of material not high (or be unlikely to affect mill efficiency and material defeated
Send) when, then can suitably reduce the first air inlet 2-1 pathogenic wind-warm, to maintain grinding area material comprehensive
Close moisture, be conducive to the stable operation of Vertical Mill 2;On the contrary, the second air inlet 3-4 pathogenic wind-warm
Then can properly increase, then be conducive to controlling the moisture in finished product materials.
In the present invention, efficient cyclone 3 and Vertical Mill 2 are integrated, and have version and close
Reason, the advantage of characteristics of compact layout, efficient cyclone 3 arranges upper and lower two material-strewing devices, and material can
Respectively enter top and the bottom material-strewing device and carry out spreading dispersion, it is possible to decrease part on efficient cyclone 3
The material concentration in region, improves the efficiency of separation;Additionally, efficient cyclone 3 also collect drying materials,
Material roughly selects classification, the selected grading function of material in one, saves equipment investment, is enterprise
Alleviate burden.
