in 1996, 214.97 million tons of iron ores were selected, accounting for 85.2% of 252.28 million tons of raw iron ores in China. Iron ore is selected to proce 85.857 million tons of iron concentrate powder, including 109.61 million tons of raw ore processed by key concentrators and 41.58 million tons of iron concentrate powder proced, accounting for 48.4% of China's iron concentrate powder output< (1) ore crushing
in China, the three-stage crushing process of coarse crushing, medium crushing and fine crushing is generally used to crush iron ore. Generally, 1.2m or 1.5m rotary crusher is used for coarse crushing, 2.1m or 2.2m standard cone crusher is used for medium crushing, and 2.1m or 2.2m short head cone crusher is used for fine crushing. After coarse crushing, the ore is not more than 1m in size, and then it is crushed by medium and fine crushing. The final proct with ore particle size less than 12mm is sent to the grinding tank< (2) grinding process
in China, most iron ore grinding processes adopt two-stage grinding process, and most small and medium-sized concentrators adopt one-stage grinding process. Due to the new process of fine screen regrinding, some concentrators have changed from two-stage grinding to three-stage grinding in recent years. Generally, the grinding equipment used is relatively small, and the maximum ball mill is 3.6m × 6m, maximum rod mill 3.2m × 4.5m, maximum autogenous mill 5.5m × 1.8m, gravel mill 2.7m × 3.6m
spiral classifier is basically used for classification after grinding. In order to improve the efficiency, some concentrators use hydrocyclone instead of secondary spiral classifier< (3) beneficiation technology
1. Beneficiation of magnetite is mainly used to beneficiate low-grade "Anshan type" magnetite. Due to the strong magnetism and good grinding and separation of ores, domestic magnetic separation plants all adopt stage grinding and multi-stage grinding processes. For coarse-grained magnetite, the former (primary grinding) is adopted, while for fine-grained and fine-grained magnetite, the latter (secondary or tertiary grinding) is adopted. A series of permanent magnetic separators developed by our country have realized permanent magnetization. After the 1970s, the new technology of fine screening and regrinding was popularized in the national magnetite concentrators, so that the concentrate grade was increased from 62% to 66%, which met the requirement of 65% put forward by the Ministry of metallurgical instry
2. Beneficiation of weak magnetic iron ore
is mainly used to separate hematite, limonite, Specularite, siderite, pseudo hematite or mixed ore, that is, the so-called "red ore". This kind of ore has low grade, fine disseminated grain size, complex mineral composition and difficult separation. Since the 1980s, the research on roasting magnetic separation, wet high intensity magnetic separation, weak magnetic flotation and gravity separation process, equipment and new kinds of reagents have been continuously improved, resulting in the continuous improvement of concentrate grade and metal recovery. For example, Qidashan concentrator of Anshan Iron and Steel Co. has adopted a new process flow of weak magnetic, strong magnetic and flotation, which has made encouraging achievements
3. Beneficiation of polymetallic syngenetic ore
this kind of ore has complex composition and various types, so the methods, equipment and processes used are also different, such as reverse flotation multi gradient magnetic separation, flocculation flotation, low intensity magnetic reverse flotation high intensity magnetic separation, low intensity magnetic positive flotation, roasting magnetic separation and other different processes used in Bayan Obo iron mine to improve the iron recovery, And comprehensive recovery of rare earth oxide. Panhua Iron Mine obtains about 53% TFE ferrovanadium concentrate by magnetic separation, and the tailings after magnetic separation obtain titanium concentrate and sulfur cobalt concentrate by low intensity magnetic scavenging high intensity magnetic separation gravity separation flotation dry electric separation, so as to recover titanium and cobalt. Iron, copper, cobalt, sulfur and other elements are comprehensively recovered in Daye Iron Mine by weak magnetic high magnetic and flotation< (4) sinter pellet technology
sinter technology is the main means of man-made rich ore in China. In 1996, a total of 160.956 million tons of man-made rich ores were proced, including 94.859 million tons of key enterprises, accounting for 58.9%, and 61.337 million tons of local state-owned enterprises, accounting for 38.1%
China's fine concentrate sintering technology has reached a considerable level. As early as the early 1950s, Anshan Iron and steel company successfully changed the proction method of acid sinter to that of alkaline sinter on the sintering machine. It was the first in the world to use hydrated lime or quicklime as flux to solve the problem of fine concentrate sintering< There are 419 sintering machines in China, with a total area of 15522m2, among which there are 22 sintering machines above 130m2, with a total area of 4107m2; 197 sintering machines of 24-129m2, with a total area of 9387m2; There are 200 sintering machines less than 24m2, with a total area of 2028m2. The 300m2 sintering machine, which was put into operation in Maanshan Iron and steel works on February 24, 1994, is the largest modern sintering machine designed, manufactured and built by ourselves except Baosteel
the main technical and economic indexes of sintering in China in 1995 are as follows: utilization coefficient 1.36t / (M2? h) The sinter grade is 53.00%, the calendar operation rate of sinter machine is 80.94%, the qualified rate of sinter is 84.92%, and the labor proctivity is 2170t / (H? A)

4. It's porcelain white material. If the material has not been dried, if the dryer works normally, if the natural color of the material is stable, if there are problems with PC + ABS material, please contact me
5. Are you sure the essence of the powder is the mineral? The raw ore is not a well burnt mineral tool and it seems that it can't be used
6. This requires a pulverizing equipment, which can be broken into 1-5mm particles by sand making machine, 1-200 mesh finished procts by ball mill, and 1000 mesh procts by ultra-fine grinding. Specific processing requirements need you to provide, and then according to the needs to select equipment.
7. The owner of the building went to the manufacturer to have a look. The quality of the crusher of Songshan heavy instry is good
8. Ordinary raw ore is processed by crusher and then grinded by mill. Because there are many kinds of fine powder in it, if you want to have high purity, you need to carry out beneficiation, which is inseparable from classification. Now there are classifiers, of course, there are also special processes, and there are also re separation.
9. Mineral processing equipment: ball mill, crusher, vibrating feeder, thickener, flotation machine, magnetic separator, classifier, filter, dryer, conveyor, vibrating screen, rotary kiln, mixing barrel, spiral chute, shaker, sand machine, sand washing machine
10. Iron concentrate beneficiation and iron separation equipment configuration
China is a country with scarce iron concentrate, and almost all the required concentrates need to be imported from India, Australia, etc. After crushing, grinding and beneficiation, the natural ore can become concentrate, and the processing ore-forming powder is called concentrate powder. According to different beneficiation methods, concentrate powder can be divided into many kinds of concentrate powder, such as magnetic separation, flotation, gravity separation and so on. The main quality indexes of iron concentrate include: 1; 2. The harmful components include: coal ash mill manufacturer; 3. Particle size; 4. Water content
the iron concentrate processing equipment refers to the proction process in which the mined ore has to go through various operations and finally get the concentrate meeting the smelting requirements<
iron concentrate beneficiation process
the mined ore is initially crushed by jaw crusher. After crushing to reasonable fineness by crusher, it is evenly sent to ball mill through elevator and feeder, and then crushed and ground by ball mill. The fine ore grinded by ball mill enters the next process: classification
the spiral classifier cleans and classifies the ore mixture based on the principle that the specific gravity of solid particles is different and the sedimentation speed in liquid is different. When the cleaned and graded mineral mixture passes through the magnetic separator, the magnetic material in the mixture is separated by magnetic force and mechanical force e to the different specific magnetic coefficients of various minerals. After preliminary separation by magnetic separator, the mineral particles are sent to the flotation machine, and different drugs are added according to different mineral characteristics to separate the required minerals from other substances. After the required minerals are separated, because they contain a lot of water, they must be initially concentrated by the thickener, and then dried by the dryer to get the dry minerals
iron concentrate beneficiation process is the most commonly used beneficiation process. Compared with the extraction of coarse ore powder, the process requirements are more strict and meticulous. The improvement of iron concentrate beneficiation technology will be more concive to the development of China's iron and steel instry, the proction of high-quality procts, and the improvement of China's international competitiveness in iron and steel process and quality. In addition to technical research, continuous innovation in equipment is also needed, Optimize the design and create new standards.
