Description
Technical field
This utility model is related to material milling apparatus, is exactly specifically to be related to for metallic ore, nonmetallic ore, the energy, new
The ring-roller mill of the various material grindings of the industries such as material, especially a kind of ring-roller mill vane sieve material that can improve mill efficiency
Structure-improved.
Background technology
As economical activities of mankind constantly develops, food and clothing lives four aspects of row as the base substance condition of human survival,
Along with the continuous development of scientific and technological level, further raising has also been obtained, people are not only to be eaten full at the aspect eaten,
Also to be eaten good, the health eaten；The basic demand that aspect firmly is taken shelter from rain from keeping out the wind, the firm, safety for becoming that requirement lives and comfortable；
It is also increasingly to pursue colourful to wear the clothes, and passes everyone individual character, and the major advance of row embodies on a vehicle, people
Walk from original by foot, develop into bicycle, automobile later, aircraft, or even people till now take spacecraft
Tourism, all embodies the improvement that the progress of scientific and technological level is lived to people.
The aspect especially lived, is to spend in sleep as people substantially have about 1/3rd time in life
, so people are extremely valued to living conditions, nest from ancient times people and occupy, develop into cave and live in concentrated communities, and to later
Banda, sun-dried mud brick room, and the various cement works in modern age, the living environment more next moon of people are comfortable, simultaneously as opposing
The needs of the natural disasters such as earthquake hurricane, the firm security performance of building require also more and more higher, so building using energy antidetonation
Building the house that material such as cement builds becomes the first-selection that the mankind build building residential house, and cement typically will be through grinding machine by original
The technique that material is levigate, the degree that raw material is levigate have very deep impact to the quality of cement, and the levigate degree of raw material is decided by mill
The selection of machine is developed into the modern times, generally raw material is carried out from ring-roller mill levigate in cement production process grinding processes.
Ring-roller mill is also known as vertical grinder, medium speed mill, be collect drying, grinding, the grinding that selects powder, be transported in one sets
It is standby, it is widely used in the grinding of the various solid materials of the industries such as cement, building materials, electric power, metallurgy, chemical industry, nonmetallic ore and ultra-fine
Material grinding.Ring-roller mill has the history in century more than one so far from utility model, and the grinding process of ring-roller mill is by one
Come what is completed, material is ground into powdery between grinding roller and mill to set lapping device (i.e. grinding roller and mill).Lapping device
Kinetic energy drives grinding roller to rotate by mill revolution, and grinding pressure is outer except grinding roller deadweight, mainly by a set of hydraulic loading system to grinding
Disk material applies pressure, requires that setting hydraulic loaded power meets material grinding and wants according to the physical characteristics and system condition of material
Ask.The thickness powder mixture that grinding is produced under wind system effect is taken grinding machine out of and enters material separation system, sorted system point
After choosing, the finished product materials for meeting system condition requirement enter material-transporting system, the material of big particle edge under gravity
Coarse powder conveying loop is returned to, until qualified.Finished product materials according to process system arrangement requirement into into
Product storage material storehouse enters combustor etc..
Vertical Mill vane in the market does not carry out the design improvement of correlation or design innovation, still rest on it is simple according to
Directly sorted by wind system, leave abrasive areas under the action of the centrifugal force, and gravity is big or middle more than wind system suspending power
Granule materials each fall within blanking port, discharge grinding machine by scraper and associated conveying devices, increase grinding machine outer circulation amount, reduce mill
Machine grinding efficiency, increases energy consumption, causes significant wastage.Chinese Patent Application No. 201010298691.x discloses a kind of for roller
The Polygonal adjustable air ring of formula grinding machine, the Polygonal adjustable air ring are arranged on the annulus formed between grinding machine shell and mill
In shape space, the Polygonal adjustable air ring includes lower BAIYE vane, and upper guide ring, described lower BAIYE vane surround mill
Disk, and weld with grinding machine shell, the lower BAIYE vane is divided into 36～48 identical parts, and each part is an independence
Air outlet, described air outlet is mainly made up of lower BAIYE vane outer side panel and a pair lower BAIYE vane oriented plates,
Described upper guiding air ring is arranged on above described lower BAIYE vane, and the structure can be adjusted and be stablized to air intake fertilizer
Control makes the material of milled export by pipeline, but still ground semi-product material cannot be separated, outer discharge capacity
Greatly, high energy consumption.
Utility model content
The purpose of this utility model is aiming at the skill that existing ring-roller mill cannot be screened to ground material
A kind of art defect, there is provided ring-roller mill vane sieve material structure-improved, arranges flase floor by the blanking port in ring-roller mill, can
