Miner clearance

1. Back up important data and photos and restore factory settings. Don't install applications from unknown sources. In addition, don't authorize in permission settings

2. You can swipe the computer to see if it can't work. Besides, the computer needs to clean up the memory on time so that it won't get stuck. The memory of the mobile phone is seriously insufficient. It is recommended to clean up the memory lightly, and then restart your mobile phone again

3. Clear the data of the mobile phone. If there are important things, save them on the network disk first, and then restore the factory settings three times. This is safer

1. Set the security level of the browser. Our common browsers all have the function of security level setting. Through reasonable setting, we can effectively filter the access restrictions of some illegal websites, so as to rece the damage to computers and personal information

3. Don't click illegal links at will

5. Turn off some sensitive functions in common communication software. Such as "people nearby" in wechat and "allowing strangers to view photos" in wechat privacy

6. Do not take photos of your family and address. If it goes on like this for a long time, as long as it is analyzed and summarized by others, the information exposed will become a complete set of information, which hides all kinds of unpredictable risks

In short, your server is infected with a virus, and now it is used as a mining machine

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
