bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan

< H2 > extended materials:

bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce

bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high

3. Mining machine name: ant S1 double blade
rated speed: 180gh / s
wall power consumption: about 360W
power input: 12V DC input (free delivery)
size specification: 135mm × 155 mm × 300 mm (assembly bracket, fan)
network connection: WiFi / Ethernet network port, support WiFi mining
cooling mode: 12 cm PWM fan and customized radiator, quiet!

4. Bitcoin has been hot recently, but I haven't talked about it, so I don't know how to use bitcoin wallet.

5. Your idea is very good. In order to make contributions to China's top 22 enterprises, you must study the major of mechanical design and manufacturing and electrical automation in the direction of mining machinery. Only by studying hard can you get the recognition of the recruitment team and appointment officer of Shenhua head office! Learning is the first major direction. Effort is the second principle

6. Original stock + virtual currency + mining machinery, three kinds of high-risk concepts of money fraud, in addition to the liar or liar

7. Some graphics cards are super frequency version, and the default setting is higher than the public version. If you want to ask this, compare the public version's parameters. If you want to see if your own graphics card has exceeded the original default frequency, compare the graphics card's own parameters

The official definition of ball mill model and specification is a series of indicators reflecting the nature, performance and quality of the proct, which is generally composed of a series of letters and numbers with a certain number. For example, brand name, grade, composition, content, purity, size, etc. In short, specification refers to the size of performance indicators, and model refers to the name (or code) obtained from the collection of specifications and models

ball mill specification: if it is expressed by the diameter and length of the ball mill cylinder, it can be shown as φ two point two × 7m、 φ two point four × 13m、 φ three × 11 m, etc

ball mill model: also, according to the diameter and length of the ball mill cylinder, it is mqgg 1212, mqG 1212, mqy 1212, mqyg 1212, etc., in which the letter part indicates the abbreviation of the ball mill equipment, and the number part indicates the diameter of the ball mill cylinder. Take mqgg 1212 as an example: this model is a wet energy-saving lattice ball mill φ one point two × 1.2m

generally, there are many models and specifications of mine ball mills, which can be divided into large, medium and small types according to the level. Taking ferrous metals as an example, a large concentrator with a daily processing capacity of 3000t, a medium concentrator with a daily processing capacity of 900-3000t, and a small concentrator with a daily processing capacity below 900t

the commonly used mining ball mill equipment mainly includes

wet energy-saving lattice ball mill. This lattice ball mill mostly deals with coarse minerals and adopts large double row self-aligning roller bearing, which effectively reces the friction force and is easy to start. Compared with other ball mills, it can save 20-30% energy

small ball mills are mainly used in small and medium-sized development enterprises. The proction scale of such enterprises is small, and the investment cost of small ball mills is low, so the investment income of users is fast, and it will not cause a waste of resources. The main ball mill equipment and model parameters suitable for medium-sized concentrator are as follows:

the above introces the definition of mining ball mill model and specification, and the distinction of model and specification according to large, medium and small type selection, and shows the model, specification and parameters of ball mill according to each level, which can be used for reference. However, in the actual concentrator, the specific model and specification of ball mill selected by each concentrator should consider the nature of materials and beneficiation conditions. It is recommended to select qualified ball mill manufacturer for test selection< br />
