Disadvantages of cone crusher

1. 1. Strictly control the feeding size to avoid jamming and blockage.

there is a formula for the design size of feeding port of jaw crusher: feeding port size = (1.1 ~ 1.25) * maximum particle size of raw material

many proction personnel do not understand it, and always take the measured feed port size as the maximum feed size. Therefore, the raw materials with large particle size exceeding the requirements become the culprit of blocking the cavity slot. Although it is not blocked repeatedly, the equipment will not operate normally for a long time every time. Therefore, strict control of raw material particle size is one of the most important preconditions to ensure the normal operation of jaw crusher

2. Strictly control the feeding amount to prevent the blockage caused by excessive feeding

many enterprises transform the silo blindly in order to improve the proction capacity, which often leads to excessive feeding

because the working principle of jaw crusher is half rhythm, if excessive materials are put in, the materials will not be broken in time, and the broken materials can not be eliminated in time, resulting in material jam. Therefore, the capacity of jaw crusher will be affected by material breaking and excessive feeding

3. Rhythm feeding, control feeding, ensure the normal operation of jaw crusher

at present, the crushing section of mineral processing enterprises is mostly fed by end chute, 2 / 3 of the whole feeder is even exposed outside the bin. Due to the remote feeding port, the feeder is completely changed into a vibrating chute, which not only has poor feeding speed, but also has serious wear. The best feeding position of the feeder should be in the range of 1 / 3 of the top of the equipment, but vertical feeding is strictly prohibited to prevent the equipment from losing its vibration ability or affecting the conveying effect
4. Adjust the angle of the feeder, make full use of the screening function of the feeder to achieve pre screening

vibrating feeder often has grate bar, which has some screening functions. However, in practical application, e to the amplitude, feeding angle and other reasons, it is easy to block the grate bar in the screening process, which makes it lose its original efficiency. In the face of this situation, many enterprises block the grate bar with steel plate and turn it into a plate feeder

in fact, the grate bar of vibrating feeder can play an extremely obvious role when it is properly adjusted. It is the best way to improve the overall flow rate by adjusting the amplitude and the angle of the feeder and fully releasing the screening function of the feeder< The processing capacity of jaw crusher is determined by adjusting the discharge port and bite angle of jaw crusher to increase the processing capacity of the equipment to the maximum. The jaw crusher is often used as coarse crushing equipment, the size of its discharge port should be based on the optimal feed size of two-stage crushing, and the size of discharge port should not be arbitrarily increased or reced

the bite angle (the angle between the movable jaw plate and the fixed jaw plate) needs to be adjusted strictly, generally in the range of 17 ~ 26 degrees (subject to the actual situation).

2. According to the market price<
the CBRC, the Ministry of instry and information technology, the people's Bank of China and the State Administration for Instry and Commerce suggest that in recent years, in the name of "financial mutual assistance", the behavior of promising high returns and luring the public to invest funds has appeared in many places in China. Its main characteristics include: 1
first, there are many names. Common are: "XX financial mutual aid community", "XX financial mutual aid platform", "XX financial mutual aid financing", "XX charity financial mutual aid platform", "XX financial mutual aid investment", "XX mutual aid community", "XX wealth mutual aid platform", etc< Second, it develops rapidly. Relying on the Internet, through the website, blog, wechat, QQ and other platforms, the publicity has a wide range
thirdly, it is confusing. Under the banner of "overseas celebrities", some claim to "destroy the unfair world financial system, break the control of financiers, and create a community for ordinary people" as the goal. Through the establishment of the so-called "fair, just, mutually beneficial and honest financial platform for people to help others", the public can get more help by subsidizing others. At the same time, he falsely claimed that "after market test, he has been mature in many countries for many years, and has hundreds of millions of members in the world" and so on
4. Strong incement. It claims that the investment threshold is low, the cycle is short and the income is high. For example, after free registration, the investment of RMB 60000-60000 can be withdrawn after 15 days, with daily income of 1%, monthly income of 30%, annual income of 23 times, and no handling charge. In addition, if participants develop others to join, they can also get extra income such as recommendation Award (10% of offline investment) and Management Award (the corresponding proportion is determined according to the membership level). There is no upper limit for development personnel and no upper limit for rebate< 5. Strong concealment. Most of them are controlled remotely by overseas personnel, and the investment funds are often transferred through personal bank accounts or through third-party payment platforms
this kind of operation mode violates the law of value, and it is difficult to maintain the capital operation for a long time. Once the capital chain breaks, investors will face serious losses. The general public is requested to raise their awareness of risks, invest rationally and prudently, and prevent their interests from being damaged. At the same time, we can actively report to the relevant departments the clues we have learned about crimes
bitcoin home and many mainstream media have reported similar virtual money pyramid schemes.

what is the file name suffix
say, the file name under Windows working interface is just arbitrary, such as the 2000 work plan of an editorial department. The file name can be expressed directly in Chinese, and the maximum length can be 256 characters, which makes people really clear at a glance. However, in the windows environment, there are a lot of file names such as calendar.exe, games.grp and so on in the installed software. Why? It turns out that these file names are determined according to the file name naming rules of DOS environment

file name in DOS environment

in DOS, the file name adopts 8 + 3 structure, that is, the file name with the longest 8 digits is separated by decimal point and followed by the suffix with the longest 3 digits, such as read.me and setup.exe. Generally, the file name is not allowed to use Chinese characters, but can only be composed of letters, numbers and some symbols. For example, read.me in Chinese is & quot; Read me & quot;, That is to remind users to look at the contents of this file before using the software to get more prompt information. What's more, it's stipulated in DOS to use suffix to distinguish different files

in DOS, executable files are the most common ones. There are two kinds of suffixes: *. Exe and *. Com (where * means any file name). They are files compiled by assembly language or other high-level languages and run directly in DOS after being compiled. Sometimes, e to multiple functions of software and small memory, it is impossible to transfer all the files into memory at one time. There may also be OVL files with the same file name, such as ws.exe and ws.ovl. In addition, there is another kind of file that can be run directly, *. Bat, that is, batch file, in which there are many commands or executable files

4. My world this game, now the most popular is PC and PE two versions, we can add a variety of homemade mod, to enrich the game play and other elements. After players join the instrial mod, there will be the electric jet backpack, but many players don't know how to fly my world jet backpack. Here's how to use the jet backpack. Let's have a look
first of all, we need to know that there are two kinds of jet backpacks: one needs oil as fuel. When using this kind of jet backpack, we need to synthesize a filling machine, power on the filling machine, put the oil bottle on the top, and put the jet backpack on the bottom, so that we can fill the backpack with oil, and we can't fill it once. After flying, it is recommended not to fly too high, because if you fall down accidentally, you will die
the other is the electric jet backpack. This kind of backpack is a powerful prop that can only be synthesized after we have an oil filled jet backpack and go to hell to get fluorite, because this backpack is better than the oil filled backpack and has a much smaller demand for energy
in fact, it's very simple to use the jet backpack. First, we need to put the jet backpack on the clothes, just like the breastplate, and then press and hold the space bar to fly. There are two modes of jet flying: fast and slow. Press h to switch the mode. If you find a key position conflict, you can go to option settings and change the key position
in the instrial mod, there are three types of batteries for electric jet backpacks: battery box, MFE and MFEs. The later the battery goes, the more electricity it can store and the faster the charging speed will be. The method of charging is to put the generator next to the battery first, not in the position with a circle, that is the output port; Then you can fully charge the battery, and then put the electric jet backpack in the upper grid; Or just put the backpack in the generator and charge it.

5.

You can only save 1800 Mini beans or 20 pieces of rocket backpack, because the unlocking condition of rocket backpack is: 20 pieces of rocket backpack. It can also be purchased with 1800 Mini beans. The unlocking steps are as follows:

enter the mini world and click my home
after entering my home, click the [illustrated book] at the bottom left

6. The rocket launcher is bound with a mobile phone. The activity is almost over

8. It's very simple. Unlock it with mini beans.

9. You create an air cube for adventure, and then you can't blow up the cube. What should you do? This should be the fault of the game, or what causes it?

10. If you unlock the fragment, it will be dected. If you unlock the fragment, you can recycle it later.
