Definitions
- iron ore taken in the mine is crushed, and the sizing process first selects the stone, and then the adasai ore powder is further removed by the sizing process. And collected separately.
- the fine powder of this sizing adapter size pour it into the kuna, extract it with this kuna, take it out as
- the land of the mine is used (usually, a bot or or). It is also called a rig, and it is called as a useful stone.
- the iron content is slightly 54 a SS, and it has a SOA 2 ⁇ 4 to 50 a SS, which is divided into two parts, and the average diameter is as low as 0,
- the particle size is 0 small as described above, there is a problem that dogging is extremely difficult.
- the fine powder with a particle size of 0 degrees which is the body of the body, can be easily stored as floating in the atmosphere, so it is generally better to store it in a pond or a swamp.
- It is a moisture fine powder ore with an average diameter of less than 0 that occurs in Yamamoto.
- the water content is 30 to 60 a S s.
- ore powder with a low moisture content, dryness, and more than the above-mentioned ones in the lighter method.
- the main component is South American tight ore with e 60 a SSSO 5 ass and 5 ass. It is preferred to use
- the main component is Afka tight ore whose main component is e54 ass, S 5 14, which is obtained as a wet in the mountain, and used outdoors. It is preferable to use what is done.
- the water content is 5 to 5 a S S.
- the above processing method the high-moisture fine powder that was used in the Yamamoto state, it is convenient to send it to the source without drying. Strokes can be greatly reduced, and as a result, the way of effective use of ore strikes can be opened.
- the dongle since the moisture is in a fine powder state, the dongle is difficult and the iron ore is used for mixing, so it does not dry It can be done.
- mixing is used to mix and granulate by adding more or less of the low moisture ore powder, drying and either according to the amount of moisture. It is easy to work in Yamamoto.
- the process of the process for example, the heavy duty machine, the stowage, etc., becomes easy.
- Fig. 3 shows the equipment mainly used for the law.
- Fig. 4 is a dog figure showing a clear sign.
- 5 is a graph showing the test results in implementation 2.
- Fig. 6 is a graph showing the results of the experiment in the second implementation.
- the water ratio is the content ratio with respect to the amount of wet raw material.
- 2 is a graph showing the relationship with the water ratio.
- No. 4 is an area that can be freely deformed, and it is an area that gradually decreases and has some resistance as the water rate decreases. The minute at this time is seven.
- shrinkage 5 (a S S).
- the water ratio (30 60 a SS) in the above-mentioned region is reduced, and the body region 2 is at least 0 20 a SS degree, preferably 5 a SS degree or less, more preferably 0 a SS degree or less. It is effective to mix low-moisture ore powder) in order to obtain a body region with a constant density. As a low-moisture ore, it is possible to use pre-wet powder ore in Yamamoto. The original iron ore powder that was originally removed is useful as a low-moisture ore powder if it has a water content of 3 to 8 a S S.
- Figure 3 shows the facilities that are mainly used in the law.
- 0 is mixing and inside is
- a number of () are arranged with the rotary shaft attached.
- This 0 is not limited to a horizontal one, but may be a vertical one. There are no restrictions on the number of rotating roots, but the granulation ability and behavior are commensurate.
- this At 0, the above is supported to rotate the device body around the rotation axis, and the rotation direction and rotation are variable.
- the rotating shaft may be eccentric or may have a structure in which the rotating shaft is supported by another rotating shaft.
- the water content is adjusted by mixing low moisture (ore powder), dry or dry or more than the above.
- a ⁇ Ore powder with moisture 9 is ore powder with a moisture content lower than that of processing 4, so long as it can adjust the amount of the substance.
- b ⁇ 20 is a powder with a water content of aSS, for example, ore powder generated in the extent of iron ore (preferably using dust etc.
- c ⁇ 2 increases the strength of the object.
- cemet quicklime, squid, and drugs it is preferable to use cemet quicklime, squid, and drugs.
- the material discharged from the exit 23 of the zero is supplied to the transport machine 24 such as a tor 25 and then further passed by 25 if necessary. It is preferable to transport it after it is naturally born. This is because many of the lumps, which are discharged from the granulation, have moisture adhering to the surface, and they are likely to be piled up to form a firm mass. In order to prevent such a situation, it is effective to regularly average with a heavy machine, and preferably to use a rolling 25 after discharge.
- the () mixed at the mountain base is transported to the load (loading) with a truck or car, and then transferred to the ore carrier, etc. It will be transported. In the morning, after being unloaded at the ground, it is basically mixed as it is, without being sunk, and as a part of the baking. be able to.
- the average When mixed with “”, the average may increase from 0 to 30. In this case, if this is used directly as a baking material, there may be a problem that the uniformity of the product is caused and the productivity is lowered.
- the reason for the landing site it is a mixture of Aihixa, Dixa, Puxa, Kissa or the like that is dried or mixed with other baked goods. If the material is pulverized to an average of 5 or less, preferably 4 or less, and molding is performed, the molding material can be improved and productivity can be increased. Aichkissa, dixa, etc. are also used for manufacturing, but can be used as they are by increasing their rotation.
- ( ⁇ 5) when it is added to other baked materials, it is further subdivided as a granulated product, and the average diameter is less than 0 and dispersed in the raw material.
- the slurry and molding material can ensure the mobility and dispersibility of the ultrafine powder, especially the tail. It can be easily dispersed in the raw material by granulation. As a result, granulation can be improved and productivity can be increased. It should be noted that the amount of water added at the time of slurrying should not exceed the value of.
- Part 4 is stored in the water in the pipe 28, and if necessary, it is sent to the pit 28 from the pit 28 and from the pit 28 or by the heavy machinery to the tack 29 or the yard 32. .
- the tail water rate is 30 60 a S S.
- the low-moisture ore powder 9 and the dried ore powder 20 and 2 are each discharged from a predetermined amount of each die 6. Then, all the slurries that have been charged are mixed and granulated in Mix 0 and then discharged.
- Calajias ore was used as the tight stone from South America.
- This calajiyas ore is mainly composed of e 6 S S S ⁇ 5 a S S 5 a S S.
- the range is 69 a s se 60 a S S 5 a S S S S a S S 5 a S S 2 5 a S S
- the ore was used as a tight ore from Aca.
- This ore is composed mainly of e 54 a S S S O 5 a S S 2 ⁇ 4 a S S.
- the range is 69 a S S e 60
- the total rate is 8 a S S, low moisture 8 2 a S S, dry use.
- the total ratio of 5 to 4 a S S, low-moisture ore powder 60 to 95 a S S, and dry ore powder up to 0 a S S, and up to 0 a S S as required are preferred. It has been confirmed that when these uses are applied to the above-described management method, the problem can be managed.
- Example 1 is an example in which the ore raw material 6 ⁇ 7 a SS is used as it is, and Invention 2 is a combination of 25 and 25 This is an example of blending.
- Invention 3 is an example in which water is poured into the landing site and added to the ground to add 5 a S S to give 2 to 22 a S S, which is treated and blended. , 30 and a height of 40O were used, and suction was performed at a constant rate of 200.
- the water is suitable for the dog according to 2).
- a SS of water is included, granulation worsens when the water content is high.
- the productivity was stable compared to the invention.
- the coke flour is 5 ⁇ a S S
