Introduction of various mining machines
1. Demon refining task: 12 rings a day. When you receive the task, you can choose to use 10 gifts to brush to 10 stars, and when you receive the reward, you can choose to use 50 gifts to get twice the reward
2. Experience , we can gain a lot of experience through experience , and get double reward by using 100 yuan treasure
3. Equipment recycling: you can gain experience and shield fragments by recycling unwanted equipment
4. Through the twelve palaces, you can gain experience and gem fragments
5. In demon killing territory, you can gain experience by using the guard to snipe the monsters in demon killing ridge
6. Escorting the escort cart, the better the quality of the escort cart, the more experience you can gain
7. Hang up the mining machine, buy Chiyue mining hoe in Tiejin mall and go to the mine cave for mining to gain experience.
even a good friend can't guarantee that nothing will go wrong
once something goes wrong, you are the only one who suffers.
The price of bitcoin mining machine ranges from two or three hundred yuan to 200000 yuan. From 2011 to 2013, the high configuration bitcoin "mining machine" increased from 10000 yuan to 300000 yuan, but its performance is much better than before. According to instry insiders, the old machine can only dig 1 bitcoin in 100 days, but now (2013) machine can dig 3.5 bitcoins in 100 days
according to the miner information published by the domestic assembly team, a miner with the lowest configuration at the price of 3000 yuan can be returned in more than 30 days according to the bitcoin mining speed. The machine with mining speed of 10G / s can dig about 0.03 bitcoins 24 hours a day, while the machine with mining speed of 13g / s can dig about 0.035 bitcoins 24 hours a day according to the computing power and difficulty of the whole network in 2013. Mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it's only hd6770, the computing power after "grouping" can surpass the single graphics card of most users. And this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Taking into account the hardware price and other costs, there is a considerable expenditure in mining< br />
1. Model and specification: ккд— 700 (px-700 / 130) feed mouth 700 mm
2. Feed and discharge particle size: feed particle size: & lt; 550 mm; Ore size: 100-160 mm
3. Type: suspension shaft type
4. Transmission mode: the motor is decelerated by V-belt pulley and connected to the transmission shaft by elastic coupling
5. Maximum lifting capacity of crushing cone: 160mm
6. Eccentricity: upper eccentricity: 21.61mm; Lower eccentricity: 33.37 mm
7. Motor model jr127-8, 130 kW, 735 rpm
8. Shaft speed: 406 rpm
9. Eccentric sleeve revolution, 140 rpm
10. Proction capacity: when the discharge port is 130 mm, the proction capacity is about 300 t / h
11. Lubrication mode: oil pump
12. Overall dimension: 2800 × five hundred and fifty-five × 4415
13. Total weight: 33706kg. 1. Overload operation of equipment is not allowed, such as too much or too large ore feeding, too small ore outlet, etc
2. The maximum lump size of ore feeding should not exceed 80-85% of the width of ore feeding mouth
3. The adjusting gap of the ore outlet should be within the range of 100-160 mm (the crushing cone is 1:3, that is, the crushing cone rises by 6 mm and the ore outlet decreases by 1 mm)
4. It is strictly forbidden for metal iron and other foreign matters to enter the crusher cavity ring operation. If they enter, they should be stopped immediately for elimination. 1. Check whether there is enough lubricating oil in the oil tank, whether the oil quality meets the requirements, and whether the oil filter is not clean
2. Test the oil pump and check whether there is oil leakage in the oil pump and pipeline
3. Whether the oil pressure is between 0.8-1.5kg/cm2
4. Check whether the oil return is not smooth and the oil flow is unstable
5. There is no looseness in the foundation screw of each part of the machine body and the frame interface screw in the frame
6. Whether the screws, pulley and key of the transmission shaft are loose
7. If there are any materials in the crusher chamber, it must be removed before starting
8. Whether the easily worn parts of the engine body (such as broken cone liner and middle frame liner) are seriously worn or cracked
9. Check whether the funnel is blocked or seriously worn
10. Check whether the hand wheel of oil immersed rheostat in electrical part is at zero position
11. Check the contact condition of motor carbon brush
12. It is not flexible to check the distribution box and operating mechanism
13. Check whether the pointer of ammeter is at zero. 1. Operation method of the equipment
(1) before operation, the equipment must be inspected item by item according to the inspection content
(2) start the oil pump first, and start the motor only after the return oil is normal
(3) pay special attention to the sound of motor and crusher when starting, and stop running immediately in case of any abnormality
(4) start feeding after normal operation of the equipment
(5) ore feeding must be stopped when the operation is stopped, and it can only be stopped when there is no ore in the crushing chamber
(6) stop the oil pump feeding
2. Start up operation sequence:
(1) first check whether the oil immersed rheostat is at the zero position and whether the short-circuit switch is open
(2) press the start button
(3) slowly transfer the hand wheel of the oil immersed rheostat to the starting position until the motor reaches the rated speed
(4) close the short circuit breaker
(5) observe whether the indication of ammeter is normal
(6) the motor shall not be started frequently, and generally it shall not be started more than three times continuously
3. Stop operation sequence:
(1) stop feeding before stop, and stop the crusher when all ores in the crusher cavity are discharged
(2) the operator presses the stop button
(3) turn the hand wheel of the oil immersed rheostat back to the zero position and open the short-circuit knife switch
(4) after power failure without notice or shutdown with load, the ore in the crusher cavity must be taken out to facilitate the start-up after power supply
Ore washing machine is a large-scale equipment used to clean ore in black and non-ferrous metallurgical mines, iron and steel, metallurgy, chemical instry and building materials. It is divided into spiral ore washing machine and cylinder ore washing machine
