What to pay attention to
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
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
(1) strictly implement the relevant provisions of "coal mine safety regulations", "operation regulations" and "operation regulations", abide by the national laws and regulations on safe proction and various rules and regulations, work with valid certificates, make good use of labor protection equipment, do not work against rules, and complete various proction tasks as required, Take direct responsibility for the safety proction of the post
(2) pay attention to the operation of the slag scraper at any time ring its operation, do not make the slag scraper operate with diseases, timely and correctly analyze, judge and deal with problems, so as to nip the accident in the bud. If it can't be handled, it should immediately report to the leader truthfully, and cooperate with the relevant personnel to analyze the cause of the fault and remove the difficult fault without delay
(3) in the work, we should concentrate on the correct and careful operation of the slag scraper, pay attention to the changes of the coal seam and roof and floor, and stop the machine immediately in case of roof fall and rib spalling, so as to assist the support worker to deal with it in time
(4) ring the operation, inspection, maintenance and troubleshooting of slag raking machine, it is necessary to pay attention to relevant safety matters to ensure work safety
(5) under no circumstances should the slag scraper be operated by personnel without a license. When the slag scraper needs to stop working or replace the digging teeth or overhaul, it must be shut down according to the safety requirements
(6) in the work, we should refuse the instruction of illegal operation, and dissuade and stop others' illegal operation
(7) to actively participate in various safety activities, post technical training, improve safety awareness and skills, report accidents in time, and protect the scene
(8) have the knowledge of coal mine disaster prevention and self rescue, mutual rescue and on-site first aid, take safety and first aid measures immediately in case of accident, actively carry out self rescue and mutual rescue, prevent the situation from expanding, protect the scene, and report to the superior immediately
(9) strictly implement the on-site shift handover system. In addition to carefully filling in the operation log and accident records, the operation of the unit equipment in this shift should be told to the next shift driver in detail, so as to pay attention to the next shift processing and operation.
has two main advantages compared with windows
(1) stable system: for example, it is very common for a host with Linux to run continuously for more than one year without downtime or shutdown. My windows system turned on black screen this morning, and then recovered after forced shutdown
(2) fast repair of security and vulnerability: Linux is used by many computer experts, so there are many maintainers, and the update and maintenance is fast, while windows is used by everyone, and it is not open source
therefore, the core system of mining machine is Linux. At present, more than 95% of the global server market choose Linux, which has been verified for a long time, and windows is not recommended as the operating system< The second key point of mining machine is: hard disk
(1) the number of hard disk bits
IPFs is storage mining, and the mining benefit is directly proportional to the size of storage capacity, so if you want to dig more money, you have to have more hard disk bits, and the mining machine with 16 disks and 24 disks is preferred
(2) hard disk installation
if you need to shut down every time you increase or decrease the hard disk, you may not get enough money to be punished and dected. IPFs mining machine needs to work stably, so it must support hot plug
(3) hard disk compatibility
supports the mixed insertion of different brands and capacities of hard disks, which can be collocated at will according to their own needs. Only by making full use of the capacity of hard disks can we maximize the revenue
the third key point of mining machine: CPU, motherboard
CPU and motherboard should be able to point out the actual working situation of multiple hard disks, and the hardware collocation should be reasonable. For example, the configuration can only support 4T multiple hard disks. If multiple 8t hard disks are inserted, it will lead to a small horse pulling a cart, causing a crash and burning the hard disk, motherboard, CPU, etc. Therefore, the hardware configuration should be rendant, and about 8t hard disk storage space should be reserved< Key points of Miner: built in mining software
the performance of built-in mining software is better, otherwise the miner's mining situation can't be well connected with the main chain, and the main chain can't read the miner's work well, resulting in data loss and mapping data error. For example, if you save 20t and the main chain only reads 10t, you will lose the reward of storing 10t. So the software R & D team must have strength. With the upgrading of technology and the analysis of mining data, software system is also needed to ensure or improve the mining efficiency.
Mining needs high-end graphics card, mining equipment is the first to eliminate NV graphics card. Mining must be done with graphics cards. The overall structure of mining equipment and ordinary PC machine is different is the number of graphics cards. You can install four or eight through pic extension
after expansion, an expansion shelf needs to be made. To fix the graphics card and other equipment, we need to get some fans on the shelf to cool the graphics card
CPU is not very important. But not lower than i5< br />
bitcoin mining machine scam is to make money by leasing or selling mining machines
the so-called "mining machine" refers to the computer that installs and runs specific software and algorithms. As we all know, bitcoin can only be obtained through long-term running algorithm of computer, and the total amount is limited. Therefore, some manufacturers have launched specially designed and optimized computer procts, known as "mining machine"
in January 2018, a mining computer named "Kodak kashminer" appeared at the international consumer electronics exhibition in Las Vegas, which aroused people's attention. But now critics point out that the mining machine plan is actually a fraud, and the publicity for profit is also false
precautions:
1. The general computer configuration of bitcoin household can not meet the requirements of bitcoin miner, so it is difficult to earn the electricity cost of a day
2. If you have to use bitcoin mining machine to dig coins, it is suggested to choose a reliable and legal platform to go more steadily. In the legal platform mining, the daily income can be seen, and a certain amount can be withdrawn
lift up the spiral of the classifier immediately after parking to avoid being pressed. If it belongs to the ball mill cylinder leakage, the feeding should be stopped first. If the time is too long, start the mill every 5-7 minutes to deal with the return sand of the classifier. Otherwise, the feeder may be crushed by the return sand and cannot be started again. At the same time, the water supply of the classifier should be stopped first, otherwise, the coarse particles will settle rapidly e to the dilution of the slurry, resulting in more sand returning and affecting the fastening screw of the cylinder
before starting the grinding machine, it is necessary to check whether the return sand groove is blocked by the return sand and whether the transmission parts are in good condition. The grinding machine can be started only when the oil pressure reaches the specified requirements and the oil flow of the front and rear big tiles is smooth. If the shutdown time is too long or the mill is started after maintenance, the crane should be used to turn the mill to prevent damage to the motor
