Principle of drill
bitcoin is equivalent to digital gold. As a generally recognized equivalent, gold naturally has monetary properties and has been regarded as a kind of currency since ancient times. Bitcoin was born in 2009 and created by a person named Nakamoto. As the earliest digital currency, it was worthless at the beginning of creation. Until 2017, the highest transaction price of bitcoin exceeded 30000 RMB. The reasons why bitcoin became a valuable digital currency are as follows:
first of all, it is like gold, as a natural mineral, The total amount of bitcoin is limited. Bitcoin can not be over issued according to its own algorithm, so there will be no rapid devaluation of currency e to excessive currency issuance. The number of bitcoin is controlled to no more than 21 million e to the algorithm, so it can not be issued in large quantities, so its value is guaranteed
then other miners will start to package the transaction generated by your new package until the next package comes out first
in the future, the mining capacity of bitcoin will be small or even zero. You still have transaction fees. The system will always need miners, and mining machines will still exist.

when building bitcoin, Nakamoto wants bitcoin to be a decentralized currency, not only for use and trading, but also for mining. But it backfired. With the increasing value of cryptocurrency such as bitcoin, mining has become an instry. The competition is more and more fierce, and the pursuit of mining computing power is higher and higher. Therefore, from ordinary computer mining, ASIC mining machine and GPU mining machine have evolved
the algorithm of ASIC mining machine is almost sha256, while the algorithm of GPU mining is different. For example, the algorithm of BTG is equihash, and the algorithm of BCD is optimized x13. Although it is not absolute, it can be simply considered that the currency of sha256 algorithm is generally mined by ASIC mining machine. Other algorithms are basically using GPU miner. There are also exceptions. Scrypt's Leyte coin used to be mined by GPU miner, but later scrypt's algorithm was also conquered by ASIC chips, such as ant miner L3 +, which is the ASIC miner used to dig Leyte coin
ASIC miner refers to the miner that uses ASIC chip as the core of computing power. ASIC is the abbreviation of application specific integrated circuit, which is a kind of electronic circuit (chip) specially designed for a specific purpose. Some mining machinery factories have designed ASIC chips specially for computing the sha256 algorithm of bitcoin, and the mining machinery using them is ASIC mining machinery. Because ASIC chip is only built for specific computing, its efficiency can be much higher than that of CPU. For example, the current mainstream ant miner S9 is ASIC miner, which uses 189 ASIC chips, the computing power reaches 13.5th/s, and the power consumption is only 1350W. As a comparison, the computing power of gtx1080ti, the flagship computer graphics card, will not exceed 60mh / s even if it is optimized well. The difference is tens of thousands of times
GPU miner refers to the miner that uses GPU graphics card as the core of computing power. Cryptocurrencies such as Ethereum, bitcoin and diamond use graphics algorithms, so the speed of computing with graphics card will be the highest. Compared with ASIC miner, GPU miner is more well-known, because it is a computer with enhanced graphics card configurationthe purpose of GPU miner is to make money, so we should pursue the power consumption ratio and maximum profit, so we should pay attention to the cost performance. Generally, the medium and high-end positioning graphics cards, such as AMD rx560 and rx570, have high power consumption ratio, which is a good choice for GPU miner. While flagship cards such as gtx1080ti and AMD vega64 have the strongest single card performance, they are not cost-effective in terms of price and power consumption
in addition, the ASIC miner also has some exotic procts, such as the USB miner of burning cat, which is slightly larger than the U disk, and the power consumption is only 2.25w, which is the smallest bitcoin miner at present

when the acceleration of the vibration of the ore drawing body is greater than the acceleration of gravity vertically, the material in the body is thrown up and jumps forward according to the parabolic trajectory, and the throwing and falling are completed in an instant. Due to the continuous vibration of the vibration motor, the ore drawing body also vibrates continuously, and the material in the body jumps forward continuously, so as to achieve the purpose of ore drawing and ore conveying

IPFs mining machine is not so much mining as charging rent. Why do you say that? If there is a user's demand for storage, the miner will rent his miner's memory as storage space, and the user will pay the miner filecoin as a reward
the working principle is simple: the user's storage demand is equivalent to didi express order, while the miner's job is to grab the order. The closer the distance, the higher the priority. Where the users are most concentrated must be Beijing, Shanghai and Guangzhou, so the miners from Beijing, Shanghai and Guangzhou have a natural advantage
compared with the traditional miner, the IPFs miner like interstellar Aoyun has advantages. It doesn't need a lot of computation, it has no noise, it consumes less power, and it's almost perfect. Even renting storage space is a bit of sharing economy, and it also requires miners to have better network speed and hard disk, fair competition, and good upward effect on the development of the whole ecology.
the beneficiation process of Belgian Magic Star Diamond generally includes preparation, roughing and cleaning. The preparation operations before beneficiation of Belgian Magic Star Diamond generally include crushing, screening, ore washing, grinding, hydraulic classification, etc. The purpose is to create good conditions for beneficiation in advance, so that the beneficiation can be carried out smoothly and obtain good results< Crushing
1.1. Crushing is the main preparation operation before the separation of Belgian magic star diamond primary ore. in the crushing stage, on the one hand, the coarse-grained ore should be fully dissociated, on the other hand, the crushing of Belgian Magic Star Diamond crystal should be reced as far as possible. In the process of ore crushing, the requirement of protecting crystal is more strict than crushing other ores. The crushing equipment is mainly jaw crusher, There are also gyratory crushers, hydro crushers, etc.
1.2. Screening
there are many places that need to use screening operation in Belgium Magic Star Diamond beneficiation. On the one hand, screening can timely separate the ore with appropriate particle size in the crushing stage, avoid excessive crushing of ore, rece power consumption and improve efficiency, It is also good for crystal protection: on the other hand, it can prepare for the next mineral processing operation. The screening equipment is the screening machine, the most commonly used is the vibrating screen, followed by the shaking screen.
1.3. Ore washing
the Belgian Magic Star Diamond placer and some primary ores contain a lot of clay minerals, It must be removed before mineral processing. Ore washing is the process of removing clay material from ore, including two stages of dispersing clay and separating the dispersed clay material from granular material. Commonly used ore washing equipment include high-pressure water gun, cylindrical ore washing machine, trough ore washing machine, etc.
1.4, The main purpose of grinding Belgian Magic Star Diamond ore is to dissociate all or most of the monomers of the fine Belgian magic star diamond in the ore, so that it can be recovered in the next step of mineral processing, Selective grinding can grind most ores to the required size, discard tailings and improve efficiency. Grinding operation is usually carried out in a rotating cylindrical mill. The mills include ball mill, rod mill and autogenous mill, The basic principle is that the medium (or ore itself) is used to grind the ore with impact phase.
1.5. Hydraulic classification
when the particle size of fine materials is separated, it is difficult to use the screening method, The basic principle of hydraulic classification is based on the difference of settling velocity in fluid e to the difference of particle size (or density). The main equipment for hydraulic classification is spiral classifier and hydrocyclone
The working principle of the grinding machine is shown in the figure. The raw material is fed into the hollow cylinder (with end caps at both ends) through the hollow Journal for grinding. The cylinder is filled with grinding media of various diameters (steel ball, steel bar or gravel, etc.). When the cylinder rotates around the horizontal axis at a certain speed, the medium and raw materials in the cylinder will fall or roll off the inner wall of the cylinder when their gravity is greater than the centrifugal force under the action of centrifugal force and friction, and the ore will be crushed e to the impact force. At the same time, in the process of grinding, the sliding motion of grinding media also has grinding effect on raw materials. The ground material is discharged through the hollow journal. Due to the continuous feeding of materials, the pressure causes the materials in the cylinder to move from the feeding end to the discharging end. During wet grinding, the material is carried away by water flow; During dry grinding, the material is taken away by the air flow out of the cylinder
