Advantages and disadvantages of heavy plate feeder
as a platform with the highest currency price in cloud mining machine project, GEC has been imitated all the time<
10 RMB miner digs 11 RMB in 30 days
100 RMB miner digs 120 RMB in 30 days
1000 RMB miner digs 1300 RMB in 30 days
10000 RMB miner digs 14000 RMB in 30 days
in fact, this is a static income. With the currency price unchanged, your interest rate in one month is between 10% and 40%, which can be increased dozens of times in one year after re investment. In addition, the currency price promised by the platform will always increase steadily, One year's income is estimated to be hundreds of times, who is not interested
in order to quickly develop to members, all cloud mining machine projects are registered to proce 11 yuan per month. Because there is no money in the early opening market, people who want to invest can not receive money, so they can only continuously raise the price of money. One month later, a large number of sheep and wool parties began to sell goods, and investors wanted to buy at a low price, resulting in the continuous decline of money price,, The more severe the drop, the more people sell. Until all platforms sell at a low price, no one dares to continue to close. This is why most platforms die within two months. Even after barely spending the first two months, there are still a large number of new users registering every day. Every new user means 11 more free coins. The increase of wool coins will make it difficult for the price of coins to rise
GEC and eco have lived a long time since last year. I'm not advertising for them here, but I don't recommend you to play, because they are basically taking orders
in March this year, a lot of crowdfunding cloud mining machine projects were launched. It can be said that all of them were dead, and they couldn't survive for a week. It was a complete scam. They are all under the guise of crowdfunding 3 points and opening 1 yuan. After all, it costs a lot to buy coins from other users, and the proceres are complicated. If you buy tens of thousands of coins directly from the platform, the cost is low and the profit is large. In the case of too few user groups, a large number of coins appear, which will only break and will not grow. In addition, platform crowdfunding makes a lot of money, and they don't pay attention to the development of the platform. They just think about how to get away from it. Many crowdfunding platforms close their websites and disband their groups after crowdfunding
everyone can build such a website. If you can program, you may only need to spend less than 1000 yuan to buy a set of source code on Taobao. Revise it yourself
if the programming is blank, you need to spend about 2W RMB to buy a full set of templates and services< As like as two peas as like as two peas as like as two peas, Br />
this is why all cloud mine machine models are exactly the same, the frames are exactly the same, what the contents are exactly the same, even the mine machine icons have their own logo. Such a platform is not a blockchain project at all. The amount of money is controlled by the platform itself. To make money on the platform, it is to sell money to investors secretly. Many people have changed from investors to fleecers just because they know the trick
the so-called trading platform is just a joke. A currency that doesn't even have a digital wallet, and a currency that can change the quantity at will, which exchange will accept it
what is your personal thinking? Making a sum is a sum. You can't think for a long time, and you can't add new functions to the platform. Therefore, I personally suggest that you should be careful when investing in this cloud mining platform, especially if it doesn't run smoothly. Even a better server is reluctant to invest. How can we develop this platform with our heart
If a platform wants to develop for a long time, it is not the same layer. It needs to be adjusted according to the development situation in different periods. The most important thing is to have actual application scenarios. No matter bitcoin or these air coins are supported by actual application scenarios, they will graally disappear with the passage of time.
Mining is a work that needs a lot of computing power to support. The reason why we use the graphics card mining machine is that the graphics card is easier to carry out a lot of repeated calculations than the CPU, so the general mining machine of the graphics card selects the graphics card mining machine
but mining also need to find a useful mining software, I have been using ha Yu miner mining, easy to use, high income< br />
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.
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).
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
therefore, it is recommended to select the motherboard of B85 chipset.
