Disadvantages of miner
No matter what form or state money exists in, it is something that everyone likes, and it has been like this from the beginning. When people establish the concept of private property, they proce the general equivalent as the certificate of exchange. And this kind of equivalent from the beginning of the shell, and then to copper, silver, gold, paper money and so on, and even a located in the Western Pacific Carol islands Yapu island using stones for trading
therefore, people who do not know much about bitcoin are advised to enter the market carefully. Bitcoin is not a hedge. Its price fluctuates greatly. People who speculate in bitcoin may get rich overnight or become poor overnight. And many countries do not recognize the legitimate utility of bitcoin, and some countries even explicitly prohibit the use of bitcoin. The above personal opinions are welcome to be criticized and corrected. Agree with me, please click like before you go, thank you! Like me, please pay attention to me, thank you again
its disadvantage is that the enrichment ratio of flaky ore is lower than that of shaker and chute, and its own parameters are not easy to adjust to adapt to the change of ore feeding properties
the spiral concentrator is suitable for treating alluvial placer, especially for those with high dissociation degree and flat shape of useful mineral monomer. For resial and slope placer, the recovery rate is lower. In addition, the ore with high mud content will rece the quality of concentrate, so it is required to enter the spiral concentrator and spiral chute after desliming and classification
the spiral washer and spiral chute are mostly used to treat cassiterite, scheelite, chromite, ilmenite, sillimanite, monazite and other minerals, and can also be used to recover heavy minerals from flotation tailings. Generally, it is used as roughing equipment, which can discard most of the tailings to get coarse concentrate. The particle size range of spiral concentrator is generally 2-0.05 mm, up to 6 mm, and the effective separation particle size is 1-0.1 mm. The spiral chute, which is the same type as the spiral concentrator, is suitable for treating fine materials and iron ore successfully. The experimental results show that the effective recovery particle size limit of spiral chute is 20 μ M. This information is provided by www.gyxxjx.com provide
(1) the main difference is that the cross-section shape of spiral groove is different. The cross section of spiral groove of spiral concentrator is approximate ellipse, which is suitable for separating coarse iron ore; The cross section of spiral chute is cubic parabola, and the bottom of spiral chute is wide and gentle, which is suitable for separating fine ore and slime. At present, spiral chute is widely used< (2) spiral washing machine and spiral chute are mostly used to treat cassiterite, scheelite, chromite, ilmenite, hollite, monazite and other minerals, and can also be used to recover heavy minerals from flotation tailings. Generally, it is used as roughing equipment, which can discard most of the tailings to get coarse concentrate. The particle size range of spiral concentrator is generally 2-0.05 mm, up to 6 mm, and the effective separation particle size is 1-0.1 mm. The spiral chute, which is the same type as the spiral concentrator, is suitable for treating fine materials and iron ore successfully.

Although many investors know nothing about bitcoin mining, they still can't resist the temptation of bitcoin price and plan to invest in the mining army. So if you also want to mine, I believe you will have a question in your heart: "what is a bitcoin miner? What is the principle of bitcoin mining machine? " To solve this problem, let's remember some popular science today
origin of bitcoin
to fully understand the origin of bitcoin, we have to mention the existing financial system
bitcoin mining machine specially used for mining. The popular digital currencies in 2013 include bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, BBQ coin and prime currency. At present, hundreds of digital currencies are issued all over the world
with the orderly implementation of cashless society, banknotes will inevitably disappear in the long river of history with the passage of time. The future digital currency is believed to be similar to bitcoin, but it is by no means a limited supply. But when the human ability to proce wealth can be completely matched by the computing power of the computer, the issuing speed of e-money is directly proportional to or slightly exceeds the computing speed of the computer to create moderate inflation. In the future, while mining, it is also creating value rather than wasting electricity. In the end, the small changes in proctivity of digital currency match the difficulty of computing power, which may be the final form of human currency
2. Just listed, there is no shortage of funds for the time being
3. The idea of the chairman is better< Disadvantages:
1. The core competitiveness needs to be improved
2. The treatment is low (without shares)
3. The management needs to be improved
generally speaking, it is good among local enterprises!
there is a formula for the design size of feeding port of jaw crusher: feeding port size = (1.1 ~ 1.25) * maximum particle size of raw material
many proction personnel do not understand it, and always take the measured feed port size as the maximum feed size. Therefore, the raw materials with large particle size exceeding the requirements become the culprit of blocking the cavity slot. Although it is not blocked repeatedly, the equipment will not operate normally for a long time every time. Therefore, strict control of raw material particle size is one of the most important preconditions to ensure the normal operation of jaw crusher
2. Strictly control the feeding amount to prevent the blockage caused by excessive feeding
many enterprises transform the silo blindly in order to improve the proction capacity, which often leads to excessive feeding
because the working principle of jaw crusher is half rhythm, if excessive materials are put in, the materials will not be broken in time, and the broken materials can not be eliminated in time, resulting in material jam. Therefore, the capacity of jaw crusher will be affected by material breaking and excessive feeding
3. Rhythm feeding, control feeding, ensure the normal operation of jaw crusher
at present, the crushing section of mineral processing enterprises is mostly fed by end chute, 2 / 3 of the whole feeder is even exposed outside the bin. Due to the remote feeding port, the feeder is completely changed into a vibrating chute, which not only has poor feeding speed, but also has serious wear. The best feeding position of the feeder should be in the range of 1 / 3 of the top of the equipment, but vertical feeding is strictly prohibited to prevent the equipment from losing its vibration ability or affecting the conveying effect
4. Adjust the angle of the feeder, make full use of the screening function of the feeder to achieve pre screening
vibrating feeder often has grate bar, which has some screening functions. However, in practical application, e to the amplitude, feeding angle and other reasons, it is easy to block the grate bar in the screening process, which makes it lose its original efficiency. In the face of this situation, many enterprises block the grate bar with steel plate and turn it into a plate feeder
in fact, the grate bar of vibrating feeder can play an extremely obvious role when it is properly adjusted. It is the best way to improve the overall flow rate by adjusting the amplitude and the angle of the feeder and fully releasing the screening function of the feeder< The processing capacity of jaw crusher is determined by adjusting the discharge port and bite angle of jaw crusher to increase the processing capacity of the equipment to the maximum. The jaw crusher is often used as coarse crushing equipment, the size of its discharge port should be based on the optimal feed size of two-stage crushing, and the size of discharge port should not be arbitrarily increased or reced
the bite angle (the angle between the movable jaw plate and the fixed jaw plate) needs to be adjusted strictly, generally in the range of 17 ~ 26 degrees (subject to the actual situation).
box crusher is a common equipment used in stone proction line.
