Cooling fan of mining machine
It is a good way to rely on the radiator of the mining machine itself, but if tens of thousands of mining machines are running at the same time in the whole mine, it is necessary to cool down the whole mine. Using negative pressure fan with wet curtain can achieve good results even in the hot summer. Negative pressure fan is now divided into galvanized plate fan and FRP negative pressure fan, and the cost is very low, FRP is much cheaper. The 18 buildings we are building in Xinjiang now all use the fans proced by Shandong runte Machinery Co., Ltd. and his family. Both of them can be used. Explain that they are used in mines. They will give us a more reasonable configuration. Experience is bought with money
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
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
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
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!
The suitable cross section of the tyre scraper is 1.6 * 1.6m; 1.8 * 1.8m; 2 * 2m section
suitable section of rail loader: 80 type 1.8 * 1.8m; 100 type 2.5 * 2.5m; 120 type 2.4 * 2.5m; 150 type, 2.5 * 2.8m; 160 Type 3.2 * 3.2m section. The selection of this model is mainly based on the mechanical equipment used to transport ore [such as rail transport, bucket car transport, shuttle car transport, etc.]
suitable section of crawler excavator loader: 80 type 2 * 2.2m; 100 type 2.6 * 2.6m; 100 type 2.2 * 2.4; 120 type 2.3 * 2.6m; 120 type 2.8 * 2.8; 150 type, 2.5 * 2.9m; 150 type 3.5 * 3.5m; 180 type, 2.8 * 3.3m; 180 type, 3 * 4m; 180 type, 4 * 4m; 200 type 4 * 4m; 220 type 4.5 * 4.5m; 260 type 5 * 5m; 312 type, 5 * 5m; 330 type 5 * 5m section
suitable section for inclined shaft with large slope: 80 crawler type 2.4 * 2.5m section with maximum working slope of 30 degrees; The maximum working gradient of 100 crawler type 2.6 * 2.6m section is 25 degrees; 120 crawler type 2.4 * 2.4m, maximum working gradient 28 degrees; 150 crawler type 3.5 * 3.5m, maximum working gradient 28 degrees; The maximum working gradient of 4 * 4m section of 180 crawler type is 32 degrees; 120 crawler type 2.8 * 2.8m, maximum working gradient 32 degrees; The maximum working gradient of 312 crawler type 5 * 5m section is 30 degrees
the main equipment commonly used in the construction of large section or full section are as follows:
rail transportation: gantry drilling jumbo, bolt support, vertical claw or rake bucket rail type rock loader (slag loader), 10 ~ 30 cubic shuttle mine car or mining big bucket car, 12 ton or 25t traction motor car, concrete spraying machine or transport pump, steel formwork jumbo combined supporting construction
trackless transportation: 3-arm or 4-arm tire and crawler electric hydraulic rock drilling jumbo, shotcrete anchor support, anchor jumbo, bucket crawler loader, 20 ~ 25 ton mining truck or pit truck [small secondary wheel and small Dongfeng], concrete spraying machine or delivery pump, integral steel formwork jumbo
the advantages of trackless shipping are high proction efficiency, good mobility, overcoming the practical advantages of working with large slope, small turning radius, strong working force, fast speed, not subject to conditions and so on. Although the initial investment is relatively high, the construction cost is low and fast, the engineering quality is good, and the safety and environmental protection are constantly improving. It is a common construction method in underground construction
