"GEC environmental protection coin" is suspected of pyramid selling, which is deceptive
"GEC environmental protection coin" trading mode has been widely spread, which takes "ecological environment protection", "zero investment", "zero risk" and "high income" as labels, and draws people into the partnership to pull down the development capital chain. Instry experts pointed out that the environmental protection coin can basically be classified as a circle. The appearance of disk circle is virtual currency, and the core is capital disk. The former's income comes from the later's capital. This model is not only suspected of ICO in disguise, but also suspected of MLM
extended information:
"GEC environmental protection coin" is obviously in line with the nature of pyramid scheme
one is to solicit customers with extremely high returns and declare that they only go up but not down, which has great attraction to investors
the second is to build the head MLM framework, build the membership mode, and realize the viral sales of GEC
Third, its sales and operation dare not be exposed to the "sunshine", but only through private means such as wechat group, which has the attributes of high concealment and avoiding supervision. Above all, the income model of "GEC environmental protection coin" has seriously deviated from the nature of bitcoin like assets, and even violated relevant laws and regulations. It is suggested that investors should guard against similar virtual currency investment model. He Nanye further stressed that this kind of mode can be identified as ICO, the core is illegal ICO, and the means is MLM modein 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)

Two e10.3 is enough for normal use
e10.3 theoretical power consumption is 2400W (measured: e10.1 power consumption is about 2200W, e10.3 power consumption is 3300W
at present, e10.1 model is more popular in the market. The old E10 is also good. Wing bit e10.3 as far as the current market is concerned, the heat is not high, mainly in terms of power consumption. It often appears that two 1800W power supplies can not afford one e10.3, and the computing power is not enough. E10.1 is more suitable for mining because the power consumption amplitude is not very large
after modification and adjustment, the output of 2.4 * 13 mill should reach 15-25 T / h
As for the problem of whether an electric transformer is needed to process the ore powder with 4r3016 Raymond mill, it mainly depends on whether the voltage of the ore powder processing plant is consistent with the rated voltage of 4r3016 Raymond mill. If it is consistent, the electric transformer can not be used. If it is not, the electric transformer is needed
this is because the rated voltage of 4r3016 Raymond mill is strict when it is used. Whether it is too large or too small, it will affect the working process of the equipment. First of all, if the voltage of the ore powder processing plant is greater than the rated voltage of 4r3016 Raymond mill, the equipment will burn out when it is working, In serious cases, the phenomenon of fire will appear, which is very unfavorable for the processing plant. Secondly, if the voltage of the ore powder processing plant is less than 4r3016 Raymond mill, then in proction, the operation of the equipment without moving will affect the processing capacity of the equipment, and it will not meet the proction requirements, which is also unfavorable for the proction of 4r3016 Raymond mill
to sum up, to open a mineral powder processing plant and process with 4r3016 Raymond mill, it is necessary to use an electric transformer, because the voltage of the mineral powder processing plant may be different from the rated voltage of Raymond mill, which will have an impact on equipment proction. The above analysis shows the impact on equipment proction when the voltage is too large or too small, From the analysis, it can be seen that whether it is too large or too small, it is not concive to the proction of the equipment, so it is necessary to use the electric transformer. For other questions about mining powder processing plant, using 4r3016 Raymond mill for processing, do you need the electric transformer www.shibangchina.com/mofenji/leimengmo/ Hope to help you< br />
