Mining machinery factory charges

1. Depending on personal preferences and advantages, those who are willing to take this as their lifelong career can get a mining plant, parcel a piece of land, and hire a few more people to watch the mining machine for you. If ordinary people enter, I suggest that they choose the platform to dig. They are too tired to dig, and the people who come here

3. Now that the dividend period of bitcoin mining is over, the output will soon be halved, and now it's a bear market for a long time. Unless you have abundant funds and a very low price source of power supply, you should never enter the mining instry again

4. The standard of charge is different. At present, domestic mining machinery manufacturers and trading platforms basically adopt the way of mining machinery trusteeship. You only need to buy their cloud computing power to mine. Equipment installation and deployment are completed by them, which is much more convenient, but you need to charge a certain handling fee as management fee or mining machinery trusteeship fee. Of course, there are also some special miner trusteeship merchants, you are responsible for purchasing equipment, they are responsible for the installation and mining, trusteeship your miner, but you need to pay the management fee.

5. Ethernet 64 bytes is the smallest. The 64 bytes include Ethernet header (Smac / DAMC / TPID). Check Ethernet again

6. As of the completion of proction rection, LTC price is $104.48.

7.

A: first, block height does not refer to the capacity of the blockchain

Second, the connotation of block height

block height is the number of blocks linked to the main chain, that is, the number of blocks connected to the blockchain

Block height is the indicator of block

2. The block has two identifiers, one is the hash value of the block head, the other is the block height

3. The hash value of the block head is the number obtained by the second hash calculation of the block head by sha256 algorithm

The

block hash value can uniquely and explicitly identify a block, and any node can independently obtain the block hash value by simply hashing the block head

4. Block height refers to the position of the block in the blockchain

The

block height is not a unique identifier

8. It is composed of power consumption, material consumption and workshop workers' wages. Please refer to the cost forecast of
1000t fluorite concentrator below
1000t fluorite raw ore is processed daily, and the grade of fluorite raw ore is 40 ℃. According to the actual recovery rate of 80%, 1000 fluorite concentrate can be proced in one day × zero point four × 8 = 320 tons. According to one crushing proction line and two ball milling flotation proction lines, the proction cost of workshop is calculated

II. Power consumption
the total power of the workshop is 2322kw, and the daily power consumption is 2322kw calculated according to the effective power of 80% and the unit price of 0.7 yuan / kWh × zero point eight × zero point seven × 24 = 31207.68 yuan. It costs 97.5 yuan per ton< 3. Material consumption
1. Steel ball: 900 kg / day, 5 yuan / kg, 4500 yuan / day
2. Mineral processing agent: 300 kg / day oleic acid × 15 / kg = 4500 yuan / day. Soda 24 bags / day × 40 kg × 2.0 yuan / kg = 1920 yuan / day. Water glass 200 kg / day × 1.5 yuan / kg = 300 yuan / day. Total 6720 yuan / day
3. Impeller: every 8 months, 64 sets × 1000 yuan / set ÷ 240 days = 267 yuan / day
4. Liner: each ball mill uses one liner for 6 months, and one liner is 15 tons × 7500 yuan / ton ÷ 180 days = 625 yuan / day. Two ball mills consume 625 yuan per day × 2 yuan / day
5. Dental splint: 4 pieces per month, 2000 yuan per piece. 267 yuan per day
6. Filter cloth: 20 yuan / day
7. Packing fee: 25 yuan per ton, 320 tons per day. twenty-five × 320 = 8000 yuan / day
8. Coal consumption: 30 tons / day for gas furnace and drying furnace, 600 yuan / ton × 30 tons / day = 18000 yuan / day

workshop staff salary: 147000 ÷ 30 = 4900 yuan / day
the salary of logistics management personnel is equal to that of workshop personnel
the daily wage of the whole plant is 4900 × 2 = 9800 yuan / day
9800 per ton ÷ 320 = 30.7 yuan / ton
v. raw ore cost
according to the raw ore grade of 40% and recovery rate of 80%, the proction of one ton of fluorite concentrate consumes 1 × zero point nine eight ÷ zero point four ÷ 8 = 3.2 tons, 80 yuan per ton of raw ore
the cost of raw ore consumption per ton of fluorite concentrate is 3.2% × 80 = 256 yuan
the total of the above four items is 97.5 + 125 + 30.7 + 256 = 509.2 yuan / ton, which is the direct cost of proction. The total cost should be added with management and other expenses
there are still some changes according to the actual situation, such as different equipment selection, different technological processes (grinding process, flotation process, crushing process) and different mineral processing recovery, the final proction cost will be different.
