12t miner
1. Machine cost: the cost of purchasing mining machine
2. Power cost: the power cost consumed by machine mining
3. Auxiliary costs: personnel maintenance, network, cable consumables, heat dissipation, etc.
for a simple example, take the mining machine of ant S9, which consumes less power on the market, for example, the calculation power is 13.5T, and the power consumption is 1400W
when the mining machine runs for 24 hours: 1.4kw * 24 = 33.6 degrees
Shenma m3, which consumes more power on the market, has a calculation power of 11.5t, The power consumption is 2150w
under 24-hour operation, the power consumption of a single machine is 2.15kw * 24 = 51.6oc
which is roughly equivalent to the power consumption of energy-saving air conditioning, but the bitcoin miner needs 24-hour uninterrupted operation, the power consumption of a single machine is very large after a year's calculation, and the step price cost of household electricity is too high, When the market is not good, the income may not be enough for the electricity expenditure, so at present, mining will choose to be hosted in the mine, which can get cheap electricity and rece the cost price of mining. The price below 30% is the ideal price, which can keep the price of bitcoin falling to a low level, and there is still some income< According to the current mining difficulty of bitcoin:
BTC revenue per ton: 1th / s * 24h = 0.00007087btc
calculated by the comprehensive 12t machine computing power, the daily output is:
0.00007087t * 12t = 0.00085044btc
then the time required for a single machine to dig a BTC:
1 / 0.00085044 = 1175 days
the time required for ten mining machines to dig a BTC:
1 / 0.0085044 = 117 days
100 days In other words, according to the current difficulty, it takes about three years for a single miner to proce a bitcoin, 3.9 months for ten miners to dig a bitcoin, and 11.7 days for a hundred miners to dig a bitcoin. The cost of a single miner is about 8500, Ten are around 85000, one hundred is 850000, less than one million, and one month's income is more than two bitcoins. According to the current price of bitcoin, the price is about 120000. So, although the income of bitcoin mining is not as good as before, it is still considerable compared with other investment projects
however, these benefits do not include decting the cost of electricity charges and later maintenance of machines, so the premise of mining is to find a mine with low electricity charges. If the quantity is large, we need to find a safe, reliable and stable mine. What's more, we need cheap electricity to lower the cost price.
because the essence of filecoin mining is storage, from the perspective of data security, most mining machinery manufacturers currently use 8t enterprise class SATA mechanical hard disk, with a price of about 1300-1500 yuan. A few mining machinery manufacturers choose 10t or 12t, and they basically choose several mainstream brands, such as Seagate, western data or Toshiba, A 12 bit blade server with 8t hard disk can have 96T storage space
SSD is generally not considered, because the cost performance is low, and if the data is lost, it is difficult to recover. If the data is lost ring the mining of filecoin, there is a penalty
generally, the CPU of mining machinery will choose inter or AMD platforms. Some mining machinery manufacturers only list inter E5 level, but do not specify that it is E5 with several cores. We must pay attention to the official requirement of minimum 8 cores
only a few single machine mining will use Inter's E5, E7 or AMD 3970x. The more mainstream mining association will choose to use the affordable amd platform with high cost performance for cluster mining. Few people choose the inter platform. Moreover, single machine mining requires high memory and low cost performance
AMD epyc7302 and 7282 series CPUs are the mainstream choice of cluster mining. They have been out of stock recently, and it may take half a month or even a month to adjust the goods. Moreover, the price of related accessories suitable for building filecoin mining machine is rising recently. For example, in 2019, the price of h11ssl-i ultra micro server main board is about 3000 yuan, At this stage, 5500 yuan can only take the futures after a week, so it is difficult for people who have no relevant channels to assemble their own accessories. Whether it's accessories or finished mining machines, it's almost one price a day
considering that each person's specific cost of taking goods is different from the cost of assembly and configuration, we can calculate the cost of a mainstream 96tb miner. If we have accessory related channels and have the strength to assemble, the cost is about 50000 yuan. If we buy finished procts directly, it is about 80000 yuan
if you want to buy the most affordable IPFs filecoin miner, you can pay attention to our company Zhonghao: old Chen Shuo coin
System). In this system, the concept of single miner no longer exists, but the concept of mole cluster
taking Avalon 40 nm mole as an example, each mole has 295g computing power. According to the actual situation of the mine site, power supply and heat dissipation, users can freely choose to stack 1-40 moles (corresponding to about 0.3t-12t computing power) into a computing power cluster unit, which can be controlled by one terminal, one network cable and one IP address. Revolutionary technological innovation has raised the flexibility and simplicity of mine layout to an unprecedented level.
Jiangxi Hengcheng mineral processing equipment arranges the main process description and proction process flow chart of mining and concentrator for you, Provide charging space for subsequent blasting work; The drilling shall be carried out in strict accordance with the hole layout requirements of the on ty blasting technician, and the error of hole row spacing shall be controlled within 10% ± 2 mm, and the error between holes is controlled within 0 ± 2 m, and the error of hole depth distance is controlled within 0 ± 0.2m
2. In the blasting section,
medium deep hole blasting is adopted, and the sundries in the blast hole are blown out with the compressed air pipe (the blasting technician shall check and accept the hole depth and hole network in the blasting area, and if the blast hole is unqualified, the blasting can not be carried out). Charge the excavated blast hole according to the formula of blast hole diameter, minimum resistance line and adjacent hole distance around the blast hole. The blasting earthquake, blasting flying rock, noise and other hazards caused by blasting should be controlled within the allowable range
In addition to the blasting quality factors, the working face should not be raised or excavated at will; It is not allowed to load the partial vehicle to make the vehicle weightless. In case of large ore (waste rock), it should be shoveled and loaded after treatment at the working face4. Transportation section
Nan Jun truck with a load of no more than 12t is used for underground transportation. During transportation, attention should be paid to the protection of underground roadway facilities, and various underground systems and transportation systems should be strictly observed
Second, the main process description of concentrator:1. Crushing section
phosphate ore is sent to hammer crusher by vibration feeder, crushed ore is screened and separated, coarse particles are crushed again, and qualified ore is sent to ball mill section by disc feeder. After being treated by bag filter, the st containing waste gas is discharged from a 15 meter high exhaust pipe
2. Wet grinding is adopted in the grinding section, which grinds the phosphorus ore and water together to form a pulp containing certain water. After the ore is milled, the graded coarse-grained ore is sent to the ball returning machine, and the qualified pulp is sent to the flotation section
3. Reverse flotation process is adopted in the flotation section. Sulfuric acid, flotation agent and flocculant are added to the pulp in the flotation machine, and the pH is controlled between 5.1 and 5.3. Air is introced by roots blower. After flotation, the pulp and tailings enter the concentrate thickener and tailings thickener respectively
4. The concentrate and tailings in the filtration section are settled by the thickener to remove most of the water, and the concentrate is filtered to the concentrate with water content of about 20% by vertical filter press. The tailings slurry is added with lime in the neutralization tank, adjusted to pH 8-9, and then pumped to the ore pond for storage. The tailings leachate is collected in the leachate filter at the bottom of the pond, and then pumped back to the beneficiation plant as make-up water
