Detailed description of the invention
The cobbing method based on gas separator and column mill that this detailed description of the invention provides, cobbing is carried out by this process, effectively can to enhance productivity and output is comparatively large, energy consumption is low, also lower to the wear intensity of equipment, and by the method, to there is good separating effect.
A kind of cobbing method that the specific embodiment of the invention provides, based on coarse grain gas separator, please refer to Fig. 1, a kind of coarse grain gas separator in the specific embodiment of the invention, this coarse grain gas separator comprises casing 7, charging aperture 1, air inlet 2, the gas entered in air inlet 2 is with pressure, the thick grain of thick grain outlet 3 generally all needs to enter column mill and pulverizes, the material of coarse grain outlet A4 and coarse grain outlet B5 can merge into coarse grain, also varigrained product can be become separately, particulate+fine powder outlet 6 generally need enter one-level or secondary dust collecting isolates particulate and fine powder, particulate and fine powder can become product separately, also coarse grain product can be ranged.
Fig. 2 is a kind of process schematic representation of cobbing in the embodiment of the present invention, feed first feeds in column mill, material feeds gas separator after column mill is pulverized, the thick grain that namely maximum particle size part after the sorting of gas separator is greater than predetermined particle returns column mill and again pulverizes, namely the material that gas separator is discharged from coarse grain outlet is less than predetermined particle becomes coarse grain product, gas in gas separator is entrained with outside particulate and fine powder discharge machine, it generally feeds in dust-precipitator, particulate and fine powder is obtained by one-level or two-stage dust-precipitator, its particulate and fine powder can all enter coarse grain product, also a kind of product can be become separately, or become fine particle product and fine powder product.
It is consistent with Fig. 2 for Fig. 3, difference is in has two coarse grain products exports in gas separator, thus creating coarse grain product 1 and coarse grain product 2, gas separator can also have plural coarse grain products export, thus produces multiple coarse grain products of multiple different-grain diameter.
In the diagram, technique in itself and Fig. 2 first feeds gas separator unlike feed, the thick grain of what gas separator was selected be greater than predetermined particle enters into column mill, material after column mill pulverizing feeds again gas separator, the coarse grain of what gas sub-elected be less than predetermined particle enters coarse grain product, its gas of being discharged by gas separator, particulate and fine powder generally enter one-level or secondary dust collecting separates particulate and fine powder, as the technique of Fig. 2, can will be summarized as coarse grain product, or become a kind of or independent two kinds of products separately.Its gas separator also can produce the coarse grain product of two or more different-grain diameter, and this process is mainly applicable in feed containing many situations being less than the material of predetermined particle.
Cobbing method provided by the invention, the pressure of sorting air-flow and flow velocity are comparatively large, can fully be blown afloat by material and dispel, and can be divided into the different product of multiple granularity, have good separating effect.And this technique also can obtain two or more coarse grained products and the fine powder product of variable grain size, and the efficiency of separation is high, the higher more power saving of system throughput, single device treating capacity is large, can process the material that moisture is large, consumable accessory wearing and tearing little, grain dirt and noise little.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses patent of the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from the spirit or scope of patent of the present invention, can realize in other embodiments.Therefore, patent of the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
