our analysis shows that the root cause of the above phenomenon is the mping caused by the lack of buffer in octagonal flow. Therefore, the following improvements can be made: a temporary garbage can is established between the crusher outlet and the ore belt, and the st collector is temporarily received. Between the temporary Ben, the belt and a valve. Then a material flow control valve is set in the valve. Setting temporary storage is to buffer the influence of large flowing materials; The material flow control valve can stabilize the export logistics; The st collector in the temporary warehouse can make part of the fine powder be treated in the early stage of the temporary storage, rece the outlet st, and also help to improve the service life of the belt. In this improvement, completely solved the st flying and material splashing point to the workshop proction and management, brought great convenience. In the process of crusher work, there may be some other problems, crusher common problems summary and troubleshooting, but also need to pay attention to time, provide crushing equipment efficiency.
. It's said that BTM batcoin has changed its name to btme now. No matter what it is called, it can't change the business of cheating investors. Now it's just cheating others to invest. This is a fake disk (a pyramid selling coin fraud project packaged with blockchain, which can charge phone charges and have business success. These things are for you to buy on Taobao. They can cheat you to invest money and connect with mainstream currencies, As long as you have money, it's better to go to the exchange and buy directly. It's no more than letting Xiao, who doesn't know, take the order. It's bullshit to go to the trading platform. A fraudster plays with blockchain and virtual miner for pyramid selling. Your real gold and silver will soon be exchanged for a pile of useless numbers.) pyramid selling currency: in the guise of blockchain technology, the technology is far from the real blockchain principle; Not to solve, optimize or change a business pain point of traditional instry as the purpose; The token is not released through the smart contract of Ethereum, and there is no formal trading platform for digital currency, most of which are traded through the platform built by the project party; Promise to rise but not fall; When you pull your head in, it pays off
about BTM Bart currency fraud group suspect has opened the capital disk, mutual assistance disk, crowd financing, finally criminals played a block chain.
the so-called blockchain, the so-called virtual currency, there are several real, there are several real hash pH value and SSH encryption protocol! In addition to a few well-known old coins, other basic is not! That belongs to ICO Shanzhai coin? Counterfeit money! We should be cautious in investment! This year, fake blockchain, fake virtual currency, we look at their own pocket, do not let cheaters disk bonus system, income to temptation! The packaging of many projects is very high and expensive. They are all paid to be packaged by others. The so-called videos are proced, the so-called white papers are also written by others, and the so-called open source code is also made by packaging companies. Now they are doing the so-called pioneering projects, and 99.99% of them are fraud projects! We are still not sober. At the end of the year, your pockets will be robbed by swindlers
The definition of mutual assistance, as the name suggests, is to help each other, which is actually a Ponzi scheme
in the introction of Ca international financial mutual aid community provided by the participants, the platform claimed that its background originated from French agricultural credit institutions, adopting a new mode of "everyone for me" and "everyone for me" to help each other, with the payment as "help" and the payment as "help". The platform does not collect money, members transfer money to each other, and there is no capital risk
realize the sharing of financial resources and obtain income. The so-called "mutual aid" actually "helps" each other's income. The premise for this mode to continue is that new people constantly join in, and the later Party's principal "helps" the first party to obtain the high interest promised by the platform
this kind of "mutual aid" has been popular in China for a long time, and the most famous one is MMM financial mutual aid platform. At the beginning of this year, 3M completely collapsed, and many people were deeply involved. However, all kinds of imitation disks under the banner of "overseas" and "mutual assistance" are still popular in wechat group
this model fully conforms to the definition of Ponzi scheme: "in short, it is to use the money of new investors to pay interest and short-term return to old investors, so as to create the illusion of making money and then cheat more investment."
the State Administration for Instry and Commerce suggests that the frequent emergence of "nine trillion international" and other network investment platforms under the banner of "financial mutual assistance" and the interweaving characteristics of the Ministry of instry and information technology and pyramid selling have huge risks, and the hierarchical relationship is formed according to the order of joining. According to the relevant regulations, once the capital chain breaks and the amount of rebate is calculated, don't be greedy for illegal profits
the operation mode of "nine trillion international" and similar entities has illegal fund-raising, set up "recommendation Award" and other bonus systems, and many investors participate in it“ "9 trillion international" and similar financial mutual aid platforms have not been approved“ Without the registration of the instry and Commerce Department, the "nine trillion international" and similar financial mutual aid platforms and companies are responsible for themselves
extended data
the risk of mutual aid:
1. Income is positively correlated with risk. The higher the income is, the greater the risk is! The higher the income, the greater the risk! The higher the income, the greater the risk
However, if you are careful, you can make a ten thousand year ship! It's not up to you whether it's the last pick-up in the Ponzi scheme3. Huzhu naturally carries the gene of MLM, and the development of offline hurts people, money and feelings. If the platform collapses and you lose money, you are offline, and all your offline people come to you for money. It must be hard for you to cross the street
4. No one is in charge now, but no one will be in charge in the future. Servers, registered places and senior executives are usually abroad, which brings a lot of trouble to the filing and investigation. Even if a certain platform is identified as pyramid selling fraud, it is even more difficult to recover
light plate feeder is a continuous feeding machine, which is suitable for short distance conveying of bulk materials with feeding particle size less than 160mm. In mines, concentrators, chemical instry, cement, building materials and other departments, it is widely used for uniform and continuous feeding from storage bin to crushing, transportation and other machinery. It can be installed horizontally or obliquely with a maximum upward inclination of 20 degrees. It is generally suitable for materials with loose density less than 1200kg / m3, block weight less than 140kg and temperature below 350 ℃
the medium plate feeder is an intermittent feeding machine, which is suitable for short distance conveying of bulk materials with particle size less than 400mm. In mines, concentrators, chemical instry, cement, building materials and other departments, it is widely used for uniform intermittent feeding from storage bin to crushing, transportation and other machinery. It can be installed horizontally or obliquely with a maximum upward inclination of 20 degrees. It is generally suitable for materials with loose density less than 12400kg / m3, block weight less than 500kg and temperature below 400 ℃
the heavy plate feeder is an auxiliary equipment of transportation machinery. It is used in crushing and grading workshop of large concentrator, cement, building materials and other departments. It is used for continuous and uniform feeding from sh10 silo to primary crusher. It can also be used for short distance conveying of materials with large particle size and specific gravity. It can be installed horizontally or obliquely with a maximum inclination of 12 degrees. In order to avoid the material hitting the feeder directly, the silo should not be empty.
The tension device adopts screw tension type
the tension support adopts section steel and bolt connection structure, with beautiful appearance and convenient assembly and disassembly. For heavy and super heavy tension devices, a set of springs is added to cushion and absorb vibration. In addition, there are the following two characteristics: (1) the screw of the tension device of medium and light plate feeder is located above the sliding seat and under the inverted equilateral angle steel, so that the screw part can not be polluted and damaged; Tension device for heavy and super heavy procts, screw through slide center 2) The tensioning device is divided into two structures: standard type and heavy type, and keeps serialization and generalization with the lower tensioning device of bucket elevator
rolling bearings are mostly used for the head and tail bearings
the head bearing seat is not supported horizontally on the frame, but is vertically connected to the frame with four bolts. On the one hand, it makes the bearing seat stress consistent with the working tension direction, improves the stress condition of the bearing seat and the connecting bolt, on the other hand, it reces the space size
the combined sprocket is used
the material of the driving sprocket is cast iron or steel, and the rim is made of high wear-resistant hardened steel with changeable tooth structure; The gearless edge of the tension sprocket is a combined type, which can be replaced. This can rece a lot of maintenance, rece maintenance costs. In addition, the replaceable gearless flange can ensure the correct and constant contact between the chain and the sprocket, and prevent the tooth surface from scuffing
backup roller wheel
the backup roller wheel of medium and light plate feeder is external type, separated from the traction roller, and has the following advantages: (1) it is easy to set the guide rail groove 2) Rece the wear of traction roller 3) Easy to manufacture. For heavy and super heavy plate feeders, fixed backup rollers are set on the frame. Centralized oil supply mode is adopted for lubrication of roller, head and tail bearing seat to ensure timing and comprehensive lubrication
hydraulic coupling
a hydraulic coupling is installed between the driving motor and the recer, which can ensure the smooth start of the plate feeder and play the role of overload protection. Chain drive is adopted between recer and main shaft, which has buffering effect, stable transmission ratio, high power transmission, adjustable center distance, and easy arrangement and installation. The drive shaft is equipped with a backstop to prevent the reverse rotation of the conveyor. In addition, for example, Yantai Xinhai Mining Machinery Co., Ltd. is equipped with automatic metering device on the plate feeder and st removal device at the head and tail, which greatly improves the work efficiency and is widely used. To sum up, although the newly formulated domestic standards are close to the international advanced standards in terms of feed volume, conveyor size, etc., efforts still need to be made to ensure the performance of the whole machine, achieve high efficiency, low energy consumption, high reliability, etc
