1. The relevant information was provided by OPP mining machinery. Because of the limitation of space, no compensation for low-level work-related injuries and space, I removed the content of Grade 10 rating. Instrial injury level identification standard is labor ability identification, which refers to the level identification of the degree of labor dysfunction and self-care disorder. Labor dysfunction can be divided into ten disability levels, the heaviest is level 1, and the lightest is level 10. There are three levels of self-care disorder: totally unable to take care of themselves, most unable to take care of themselves and some unable to take care of themselves. The standards for appraisal of labor capacity shall be formulated by the labor and social security administrative department of the State Council in conjunction with the health administrative department of the State Council

2. bitcoin has been hot recently, but I haven't talked about it, so I don't know how to use bitcoin wallet.
3. Different models and prices will not be the same. The cone breaking capacity of xingkuang machine is about 20w-30w
4. The above is the technical parameters of spring cone crusher, you can refer to it
5. 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).

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).
6. Literally, one is multi cylinder, the other is single cylinder; Safety routine: it must be the high efficiency of multi cylinder
it depends on your proction requirements and efficiency. From a certain point of view, it's not wise for a single cylinder or multiple cylinders to be good or bad
in the hydraulic cone crusher, the single cylinder hydraulic cone crusher is characterized by simple structure, few parts, beautiful appearance, convenient maintenance and easy automatic control, but because there is only one oil cylinder, the crushing force is slightly insufficient, and the star arm of the upper frame is a weak link. Therefore, when crushing hard materials, sometimes it is not enough. In addition, because the adjustment mode depends on the lifting of the moving cone, the wear of the rolling mortar wall is more uneven in the case of uneven feeding.

7. In the process of ore crushing, according to the operation mode and the particle size of crushing procts, crushing equipment can be roughly divided into crusher and grinding machine
the crusher is used in the coarse crushing stage. Generally, the feed particle size is larger, and the proct particle size is also larger, usually more than 6 mm (- 6 mm accounts for less than 60%). Their basic feature is that the working parts do not contact each other and keep a certain gap. According to the crushing mode and principle, it can be roughly divided into the following four types:
(1) jaw crusher (also known as Laohukou), which is an old and widely used crushing equipment. The crushing action is that the moving jaw periodically approaches and leaves the fixed jaw. Crushing the ore block between the two jaw plates (mainly crushing) and discharging (falling by self weight) is intermittent crushing. According to the movement characteristics of moving jaw, jaw crusher can be divided into simple swing (double toggle plate) and compound swing (single toggle plate)
(2) cone crusher is a continuous crushing equipment. According to the feed and proct size, cone crusher is divided into circular cone crusher and medium and fine cone crusher. According to the length of the parallel belt B (the gap between the moving cone and the fixed cone) of the crushing chamber, it can be divided into standard type, intermediate type and short head type cone crushers
both rotary cone crusher and jaw crusher belong to coarse crushing equipment, but because the cone crusher works continuously, its proction capacity is much larger than jaw crusher when the feeding properties are the same. The standard type and the short head type are used for medium crushing and fine crushing equipment respectively, while the intermediate type is between the two. Generally, it is used as the second crushing equipment when two-stage crushing
(3) impact crusher, which uses the "free" crushing principle of impact force to crush ore, the ore is crushed in the crusher by the impact of impact plate (plate hammer) and impact plate, and the complex effect of multiple collisions between ore. Therefore, the crusher has the advantages of large crushing ratio, high efficiency and less over crushing. It is a promising crushing equipment
(4) roller crusher. The ore is fed into two opposite rotating round rollers (smooth or non smooth) from the upper part. It is drawn into the crushing chamber by the friction between the material and the roller surface and crushed by the roller. The crushed ore is discharged from the gap between the two rollers by gravity. It is mainly used for medium and fine crushing of medium hard and brittle materials.

8. Do you mean crushing equipment for iron ore mining or crushing equipment for mineral processing
if it is a crushing equipment for mineral processing and the scale is large, the first stage rotary crusher + second stage and third stage cone crusher can be selected. If the scale is small, you can choose a jaw crusher + two-stage, three-stage cone crusher.

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.
