NTC miner
the popular point is to use the computing power of your computer to solve mathematical problems, and then give you a certain amount of bitcoin in return
bitcoin mining has gone through three stages: CPU, GPU and ASIC. At present, bitcoin mining needs professional ASIC mining machine. At present, Avalon, butterfly lab and roasted cat are the most famous mining machine manufacturers in the market, but butterfly lab in the United States likes to evade tickets, while roasted cat only sells mining machines with small computing power. Avalon has proced the world's first ASIC miner, and Avalon has delivered the first three generation chip orders. Avalon3 is about to enter the market
and now you need to join a mining pool, because the chance of digging bitcoin alone is very small, I hope you can.
the machine is a horizontal cylindrical rotating device, with outer gear drive, two bins and lattice ball mill. The material enters the first bin of the mill evenly through the feeding device through the feeding hollow shaft screw. In the bin, there are stepped lining plates or corrugated lining plates, which are filled with steel balls of different specifications. The rotation of the cylinder generates centrifugal force to bring the steel balls to a certain height and then fall down, resulting in heavy impact and grinding on the material. After rough grinding in the first bin, the material enters the second bin through a single-layer partition board. The bin is inlaid with a flat lining board and steel balls to further grind the material. The powder is discharged through the discharging grate plate. Working characteristics: conical ball mill has higher cone frequency and amplitude, and its environment is worse. Some of them even participate in the taper. Therefore, there are higher requirements for the anti vibration performance of ball mill. Small ball mill in China has been developed, and large ball mill needs to consult with the manufacturer. Anti vibration ball mill is a relative concept, Its service life is far lower than that of ordinary ball mill. Because it is a special ball mill, it has relatively high price and difficult maintenance. Sometimes it needs professional maintenance in the manufacturing unit, so the use cost is high. The ball mill should be designed as far as possible without vibration
the common structure of cone ball mill can be used in small cone ball mill, which can be installed horizontally, obliquely and vertically. At present, 23 kW is the most widely used in China, and the frequency is 980 R / min
Under the leadership of the National Standardization Management Committee, the National Technical Committee 88 on mining machinery of Standardization Administration of China (abbreviated as ntcmm) is specifically organized and managed by China Federation of machinery instry, with the serial number of SAC / TC88. The Secretariat is located in Luoyang mining machinery engineering design and Research Institute (formerly Luoyang Mining Machinery Research Institute, Ministry of machinery instry)
the national standardization of mining machinery instry started in 1957. After years of exploration and development, in 1982, the "mining machinery standard review committee" was established in the original machinery instry. In 1987, the National Mining Machinery Standardization Committee was established with the approval of the former State Bureau of standards. In September of that year, a meeting was held in Luoyang City, Henan Province. The first committee was composed of 28 members. In 1996 and 2001, the third committee was composed of 46 members. Up to now, there are more than 300 national standards and instry standards in mining machinery instry
