In order to further understand the content, features and effects of the present invention, the following examples are hereby given, and coordinate attached drawing
Detailed description are as follows：
It is a kind of can wet type grinding vertical roll grinder, the center of top of the vertical roll grinder is equipped with for make-up water and raw material
The feed cone 6 fed, water replanishing device 7 is equipped in the vertical roll grinder, and the water replanishing device 7 includes at least two water pipes
11, the water pipe 11 enters the feed cone 6 by 1 top of shell of the vertical roll grinder, downward along 6 inner wall of the feed cone
Extend, while being internally provided with distributive pipe 11 in feed cone 6 and moisturizing is carried out to the grinding roller 2 and mill 3.
The present invention is not easy to form dust pollution；Wet type is to feed grinding machine with pulpous state to mine, is easy to wash by abrasive surface impurity
It goes, and feed quantity is easy to control, and because using delivery pump and pipeline, installation cost and expenditure on power few；Meanwhile wet classification efficiency
Higher than dry classification, granularity is easily controllable to be changed in narrow range, is conducive to requirement of the follow-up sorting operation to granularity；Wet type
Mixing it is also more uniform than dry type；The heat that wet type grinding generates is easier to exclude；Dry type grinding uses air classification mode, energy
Consumption is higher, and technique is more complex；Wet classification energy consumption is relatively low, and technique is relatively easy.
For further, it can also consider in the present invention, the vertical roll grinder does not include built-in powder concentrator.
The present invention does not include built-in powder concentrator, reduces energy consumption, reduces equipment investment.
For further, it can also consider in the present invention, the vertical roll grinder further includes collecting chamber 4, material scraping plate 5
With power plant 8, the power plant 8 includes motor and speed reducer, and the motor output shaft is connected with speed reducer input shaft, institute
It states mill 3 with speed reducer output shaft to be connected, the enclosure space being located at around mill 3 constitutes the collecting chamber 4, the collecting chamber 4
Positioned at the lower section of shell 1, the material scraping plate 5 connect with mill 3, the drive rotation of material scraping plate 5 of mill 3, the vertical roll grinder it is interior
Portion is equipped with grinding roller 2 and mill 3, and the grinding roller 2 is at least two cone rollers, and the mill 3 is square position structure, 3 edge of the mill
Equipped with collet.
Power plant 8 of the present invention is driven by motor, by speed reducer band movable grinding disc 3 rotate, collecting chamber 4 will be crossed by grinding and
The slurry overflowed outside mill 3 is collected, these slurries are scraped to scum mouth and are discharged by material scraping plate 5, are classified subsequently into vibrating screen；
The effect of collet is control thickness of feed layer maximum value.
It should be pointed out that 6 lower end discharge gate of the feed cone is set to 3 center of the mill.
It should be pointed out that the upper surface of 3 lower part of the mill is equipped with sealing cover, the sealing cover covers the deceleration

Feed cone 6 is ground, and the fine particle product outlet of the vibrating screen connects skewed slot and enters subsequent job.
It should be pointed out that the screen mesh size of the vibrating screen is 3mm.
Some researches show that：When calculating unit work consumptiom needed for industrial mill using BOND the grinding work indexes, dry milling
Correction factor generally takes 1.3, and wet grinding generally takes 1.0, i.e., dry milling power consumption is 1.3 times of wet type.It will thus be seen that wet
Formula ore grinding all increased than the breaking capacity and energy efficiency of dry milling.
As an example, in the present invention, when grinding machine works, raw ore feeds feed cone 6 at the top of grinding machine, simultaneously with make-up water
3 center of mill is fed, is spread out to 3 surrounding of mill by centrifugal force；Grinding concentration about 70~85% is advisable；Mill 3 is in motor band
Dynamic lower rotation, while grinding roller 2 presses downwards, and ore is made to obtain comminution effect；Levigate ore pulp overflows mill 3 from collet,
Collecting chamber 4 below grinding machine is fallen into, is scraped from scum mouth by scraper plate, comminution process is completed.
As an example, in the present invention, water replanishing device 7 is applied at feed cone 6, and the moisturizing into feed cone 6, moisturizing is along interior
Conic section tangential direction is injected；Feed cone 6, case inside do anti-corrosion processing.
In conclusion that the present invention can provide a kind of grinding energies is low, comminution is efficient can wet type grinding vertical roller grinder
Machine.
Above example describes the invention in detail, but content is only the preferred embodiment of the present invention, no
It can be believed to be used to limit the scope of the invention.Any changes and modifications in accordance with the scope of the present application,
It should still fall within the scope of the patent of the present invention.
