Zhejiang mining machinery
when you buy a video card miner, go to a local computer dealer and buy a professional chip miner, usually on the mining platform
here are some introctions to the graphics card Mining:
the graphics card mining machine is a computer with 6 medium and high-grade independent graphics cards. The first display card miner is rx470 / rx480. Because it is too hot, AMD's display card manufacturers are in short supply, and the goods are scattered to a few pieces, so many of them are mining with gtx1060, and the 1060 is out of stock. They start mining with gtx1050ti 4G, but there are not many now
1060 is about 0.07 per day, power 1200W +, computing power 125 ~ 135mh / s
1050ti is about 0.05 per day, power 700W, computing power 75 ~ 85MH / s
basically, the price is directly proportional to the performance, maybe 1050ti is slightly ahead, but the combination of 1060 is recommended for single person and single mining
hand printing, without and paste, is adopted.
The most advanced bitcoin mining machine, one to two years to dig out a bitcoin, bitcoin mining is now too difficult. If you want to dig, you can dig ether currency. Now it is steadily appreciating every day. According to the current development trend, it will be able to recover its capital in about seven months, and then it will be profitable< br />
As of July 24, 2020, the state has not issued any laws to prove that bitcoin mining machine is illegal
bitcoin mining machine is one of the ways to obtain bitcoin. Bitcoin is a kind of network virtual currency proced by open source P2P software
it doesn't rely on the issuance of specific monetary institutions, and it is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
extended data
the issue and transaction of bitcoin are realized by mining, and it is cast at a certain but slowing rate. Each new block is accompanied by a certain number of new bitcoin from scratch, which is used as a coinbase transaction to reward the miners who find the block
the reward for each block is not fixed. For every 210000 blocks mined, it takes about four years, and the currency issuance rate is reced by 50%. In the first four years of bitcoin's operation, each block created 50 new bitcoins. Each block creates 12.5 new bitcoins. In addition to the block award, the miner will receive a handling fee for all transactions within the block<

From the perspective of equipment level, China's open-pit mine equipment can be roughly divided into three types:
(1) small mine equipment is single, small and not matching; Some processes are still manual labor
(2) medium and indivial large mines have a high degree of mechanization, but the equipment is old and backward, and the efficiency is not high
(3) a few large-scale mines use imported or domestic modern equipment, such as rotary drill, electric wheel truck, large capacity excavator, high-power bulldozer, etc., to form a complete set of operation line, which has high efficiency
Drilling machinery is divided into rock drill and drilling rig, and drilling rig is divided into open-pit drilling rig and underground drilling rig. Rock drill is a kind of machine which is used to drill blast hole with diameter of 20-100 mm and depth of less than 20 m in medium hard rock. According to its power, it can be divided into pneumatic, internal combustion, hydraulic and electric rock drill, among which pneumatic rock drill is the most widely used; According to the working mechanism of crushing ore and rock, open-pit drilling rig is divided into wire rope percussion drilling rig, down the hole drilling rig, cone drilling rig and rotary drilling rig. Because of low efficiency, wire rope percussion drilling rig has been graally replaced by other drilling rigs
roadheader is a kind of mechanical equipment which can directly crush ore and rock by rolling the rock surface with the axial pressure and rotary force of cutter. The cutter used includes disc hob, wedge hob, ball hob and milling cutter. According to the different driving roadway, it can be divided into raise boring machine, shaft boring machine and drift boring machine
