Double platform vibration drawing machine
when the acceleration of the vibration of the ore drawing body is greater than the acceleration of gravity vertically, the material in the body is thrown up and jumps forward according to the parabolic trajectory, and the throwing and falling are completed in an instant. Due to the continuous vibration of the vibration motor, the ore drawing body also vibrates continuously, and the material in the body jumps forward continuously, so as to achieve the purpose of ore drawing and ore conveying

hope to adopt.
Vibrating feeder: if the ore is evenly broken, small in size and good in fluidity, swing type or wave type can be selected. It is suitable for elliptical vibration type and directional vibration type
double mass vibrating feeder: the principle of double mass near resonance inertial vibration is adopted. Single row or double row shear rubber springs are arranged at the top and bottom, and the lower pressing plate is connected to the balance body by bolts, and then the left and right side plates are connected with the groove body. It has compact structure, stable starting under constant pressure, and is not affected by the load and jamming of the tank material. The feeding particle size (0-850mm) is large (8-1800t / h). It can be equipped with stepless frequency converter to realize frequency conversion feeding and batching, and remote microcomputer operation and control

In the forum session of this summit, the guests on the scene had an in-depth discussion on the theme of "trends and trends of media", and made wonderful interpretations according to their own enterprise characteristics and instry experience. Ms. Ma Jinghua, former vice president of public relations of BMW Huachen, brand director of Volkswagen and now vice president of International Department of Dalian Tiansi museum ecation group, said:
I very much agree that any business must have a strategic goal. Its vision, mission and goal should be clear. 5g and blockchain are technologies, and this primary and secondary must be clear. Especially in the future, brand communication is very important. The basic principles of brand building, the relationship between elements and consumers, how to maintain the value of the brand, how to measure the value of the brand, and the basic business rules will not change. I hope you can work hard to understand these rules, learn these things and keep them in your mind, At this time, you won't lose your direction when the big waves come, and you won't be dazed by the colorful technology
specifically, 5g is characterized by low delay and high transmission speed, which puts forward high requirements for the quality of media personnel and public relations personnel. Then there are changes in the channels and methods of content distribution. The Internet of everything, media of everything, smart city and smart home brought by 5g, including everyone, have become media. In this case, how do you influence the public and spread your information? We should consider it from a higher level, because of its low delay, high speed, coupled with the rise of short video, the sense of customer experience is high, and the requirements are also high. As a public relations and media, how to adapt
as a media company or media personnel, we should have a clear strategy. What should my company do when the two technologies are interwoven. In my opinion, 5g or blockchain is actually the best tool to improve influence. We seize this opportunity, conform to this trend and take advantage of it to strengthen ourselves. It's an opportunity. It's an era of influence. It's very rare
I learned a little bit about blockchain because one of my classmates wrote the first book on blockchain technology popularization in China. As Mr. Fu said, the core of blockchain is the protection of the originator, the protection of the originator and the works, which gives the originator a platform and standard to measure their self-worth and procts. This provides a great protection for the creation of media and the creation of content by media practitioners. In the future, as long as everything we write is good and unique, there will be more than n people to buy and praise it. In fact, it has become very popular in the United States
blockchain is also helpful for distribution channels. Any rough and disorderly things you make will have traces, and the good things you write will be confirmed, widely quoted, and create higher value. You have the right to be yourself. Therefore, media companies must make blockchain strategy as soon as possible, seize the opportunity

if the fan is used for a long time, it will inevitably proce noise and st. What about noise rection and st cleaning? Firstly, the method of recing noise is introced. The noise is caused by the pulsating force of the blade acting on the air flowing through the fan. The noise can be reced according to the following rules:
1. An acoustic resonator is set up at the tongue of the cochlea. When the sound wave is transmitted to the resonator, the hole diameter and the sound wave of the gas in the cavity act on it to move back and forth, so that part of the sound energy is lost e to heat consumption and the noise is reced
2. The distribution of air velocity and pressure behind the cascade is not uniform. When the air flow moves relative to the blade, there is a volute tongue at the outlet of the rotor blade, which will interact with the volute tongue to proce noise. A larger radius of the front end of the tongue is appropriate to rece the rotating noise and vortex noise< 3. The serrated structure on the inlet and outlet sides of the rotor blade can make the laminar boundary layer of the air flow on the blade transform into turbulence earlier, so as to avoid the unstable wave in the laminar boundary layer leading to vortex separation and rece the noise
4. Under the condition of the same air volume and pressure, for the impeller with strong forward blades and multiple blades, it is beneficial to increase the aerodynamic load of the cascade, and the circumferential velocity on the outer circle of the impeller blade can significantly rece the noise
5. By making the volute tongue inclined, the periodic pulsating velocity of the flow in the impeller cascade can be reced, and the rotation noise caused by the interaction between the volute tongue and the volute tongue can be reced. Because the effect area of the pulsating aerodynamic force in the same phase is small, the radiated noise is reced
the problem of noise is solved, and then the problem of cleaning is solved. It is not difficult to dismantle and wash the fan. The key is to pay attention to the details
1. The upper part of the main air ct and the rotor of the horizontal split unit should be removed, and the lower part of the main air ct, the bearing seat and the base should be assembled on the foundation, and then leveled with a pair of inclined shim
2. The different axial degrees between the machine shaft and the motor shaft of GZG inertia vibration feeder for horizontal and vertical splitting units of scraper conveyor in Shuicheng coal mine, the radial displacement should not exceed 0.05mm, and the tilting step should exceed 0.2g1000; The longitudinal unevenness of the unit shall not exceed 0.2/1000 for vibrating drawing machine and the transverse unevenness shall not exceed 0.3/1000
3. The non levelness of the vertical unit should not exceed 0.2/1000, and the radial displacement should not exceed 0.2/1000 for the different axial degrees of the transmission shaft and the motor shaft of the screw coal feeder measured on the wheel hub with a level instrument
4. The air chamber of the single-stage crusher should be placed on the foundation of the vertical splitting unit, leveled with a pair of inclined pad iron, and then the bearing seat should be installed. The bearing seat and the bottom plane should be in uniform contact, and the different axial degrees of the two bearing holes to the common axis should not exceed 0.05mm; After grinding and scraping the bearing bush, place the main shaft flat on the bearing bush cone crusher, fix it on the main shaft head with a scriber, measure the different axial degrees of the main shaft and the inlet chamber with the seal ring of the inlet chamber as the benchmark, and the value should not exceed 2mm, and then install the impeller, dry-type power transformer casing, stator and diffuser in turn.
