1. The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
mining machine is a tool for procing and mining bitcoin

3. Hello, miner trusteeship,
if there are only one or two miners, you can choose to dig at home, rent an empty house in a slightly larger remote point, and use it as a special machine room, so that the miner will not disturb the people and it is convenient for you to visit at any time
if there are dozens or even hundreds of mine machines, it is recommended that you choose mine trusteeship. First, the electricity charge of mine trusteeship will be cheaper than that of indivials, and there are special personnel to take care of mine machines. The inconvenience may be that most of the mines are located in Northwest and southwest provinces, which may not be convenient for you to understand the actual situation, but you can also choose the background software to monitor your own mine machines, The selection of specific mines can be evaluated according to the quotation
if you don't know much about this area before and don't have a miner, you can choose to buy cloud computing power. This kind of miner is only used in a different way. The ownership of the miner doesn't belong to you, but is rented to you

the advantage of the mineral machinery trusteeship lies in the fact that it is not easy to manage; Annual regular electricity subsidies, cheap electricity&# 130; 24 hours a day without power cut to dig money; There is operation and maintenance technology in the mine 24 hours on call, problems can be solved immediately&# 132; If the power board is broken, it needs to be returned to the factory. The company will have machines to make up the power. However, it is suggested that when you choose a mine, you should consider the quotation of mine management fee and electricity fee
if you have any other questions, please ask me. I hope I can help you, thank you!

4. 600000 yuan bought a 61 square meter house in Taiyuan mining machinery dormitory in 1983. It's worth it!

5. Hello, the miner trusteeship depends on the situation
if there are only one or two miners, you can choose to dig at home, rent an empty house in a slightly larger remote point, and use it as a special machine room, so that the miner will not disturb the people and it is convenient for you to visit at any time

6. Almost none. It's not worth it. Prospecting should be low-cost and can be used, which is different from the traditional data center computer room. No precision air conditioning, UPS these, the latest integration of container mining machine, a truck to go, where the electricity is cheap.

7. I personally think the house at the east gate of Fangshan mining machinery is a public house, which can be transferred, because if it's a public rental house, it can't be transferred

8. 1. For small and medium-sized concentrators with fewer grinders, the vertical configuration scheme (the center line of the mill is perpendicular to the center line of the powder bin) is generally adopted. The main advantages are easy to operate, easy to pulp from the mainstream and pulp distribution
2. The length of grinding span should be adapted to the separation span. If the separation span is too long, parallel configuration can be considered
3. The grinding machine of multi-stage grinding can be configured in the same bay or in two bays. The advantages of two span configuration are simple process and few circuits, but when there are not many grinders, it is more economical to configure in one span
4. The angle of belt conveyor used for grinding machine feeding should not be too large, generally less than 18 °， The receiving point of the feeder should be stable, and the captain depends on the installation requirements of the electronic scale. In order to ensure the accuracy, it is better to use the tail of the heavy hammer to tighten the belt to maintain a certain tension
5. Crane capacity shall be selected according to regulations. When multiple cranes are used e to the large number of mills, the double deck layout method should be avoided to rece the height of the plant
6. The special maintenance equipment should be selected according to the requirements of the manufacturer. The grinding machine with a diameter of more than 5m should generally be equipped with a special manipulator, and there should be enough space and area in the configuration
7. When grinding across the surface, enough slope should be maintained, generally 5-10%, and good sewage and sand discharge systems should be set up to meet the requirements of environmental protection and rece metal loss
8. Due to the large noise in the workshop, the relevant offices, living rooms and automatic control rooms should be arranged far away from the sound source, or appropriate sound insulation measures should be taken
9. The steel ball warehouse should be located near the maintenance site, and the transportation convenience should be considered in combination with the terrain. In order to improve the condition of ball cleaning, a waste ball bin should be set up on the maintenance site to facilitate the transportation of waste balls by truck
10. The area of the maintenance site shall be selected according to the provisions of this manual. The gate of the site shall be consistent with the external transportation conditions. The specifications of the gate shall meet the installation and transportation requirements of grinding machine parts and components. When the overall size of the equipment is large, the installation hole should be reserved

9. Excessive feeding of ball mill will cause "belly swelling" of ball mill
the so-called uniform feeding means that the feeding quantity is stable and the feeding particle size composition is unchanged. If the feed rate is not properly increased, the proct grain size of the mill will be coarsened and the amount of sand return will be increased. The ball mill may cause the phenomenon of "bulge", that is, overload. At this time, the sound of the mill is ll and weak, and the grinding effect is lost. At this time, the ore feeding should be reced or stopped immediately, the overflow concentration should be increased, and the ore feeding should be carried out after the mill returns to normal operation
too little feeding amount of ball mill will cause "injury" to the lining plate of ball mill
if the feeding amount is insufficient, the particle size of discharged ore will become finer and the amount of returned sand will be reced. When the feeding amount is significantly insufficient, the sound of the impact between the lining plate and the steel ball will occur, resulting in the useless consumption of grinding medium and lining plate. When the feed rate is constant, the increase or decrease of feed particle size will proce similar phenomenon as when the feed rate is more or less. Therefore, when the mill is in normal operation, it is necessary to ensure that the ore feeding is uniform and the particle size is uniform, and the fluctuation must not be too large. Only in this way can a good proction index be obtained
whether the ball mill can feed ore evenly depends on the continuous observation of the operators. Generally, large fluctuations occur ring the shift handover, so it is necessary to carefully check some places. It is necessary to carefully check the operation of the main bearing and transmission bearing of the mill, the transmission system of the classifier and the feeder, check whether the amount of lubricating oil is sufficient, understand the feeding of grinding medium, and understand whether the ore reserves in the ore bin, the discharge of the mill, the overflow and sand return of the classifier are normal. Only careful to do these, can ensure the smooth operation of the ball mill, stable proction index.
