Crushing equipment is the mechanical equipment used to crush minerals
crushing operations are usually divided into coarse crushing, medium crushing and fine crushing according to the size of feeding and discharging particles. The commonly used sand and stone equipment include jaw crusher, impact crusher, impact crusher, compound crusher, single stage hammer crusher, vertical crusher, rotary crusher, cone crusher, roller crusher, double roller crusher, two in one crusher, one-time molding crusher, etc
it can be divided into six categories according to crushing mode and mechanical structure characteristics (action principle)
(1) jaw crusher (tiger mouth). The crushing action is that the movable jaw plate periodically presses the fixed jaw plate to crush the ore block sandwiched in it< (2) cone crusher. The ore block is between the inner and outer cones, the outer cone is fixed, and the inner cone swings eccentrically to crush or break the ore block
(3) roller crusher. In the gap between two opposite rotating round rollers, the ore block is mainly crushed continuously, but it also has the function of grinding and stripping, and the toothed roller surface also has the function of splitting
(4) impact crusher. The ore block is broken by the impact of fast rotating moving parts. Belong to this category can be divided into: hammer crusher; Cage crusher; Impact crusher
(5) grinding machine. The ore is crushed by the impact and grinding of grinding medium (steel ball, steel bar, gravel or ore block) in the rotating cylinder
(6) other types of crushers and grinders. Drilling machinery is divided into rock drill and drilling rig, and drilling rig is divided into open-pit drilling rig and underground drilling rig
① rock drill: it is used to drill blastholes with a diameter of 20-100 mm and a depth of less than 20 m in medium hard rock. According to its power, it can be divided into pneumatic, internal combustion, hydraulic and electric rock drills, among which pneumatic rock drill is the most widely used
② surface drilling rig: according to the working mechanism of crushing ore and rock, it can be divided into wire rope percussion drilling rig, down the hole drilling rig, cone drilling rig and rotary drilling rig. Because of the low efficiency, the wire rope percussion drill has been graally replaced by other drills
③ downhole drilling machine: when drilling borehole with diameter less than 150 mm, in addition to rock drill, 80-150 mm small diameter down the hole drill can also be used. Using the axial pressure and rotary force of the cutter to roll the rock surface, it is a mechanical equipment for directly crushing ore and rock. The cutter used includes disc hob, wedge hob, ball hob and milling cutter. According to the different driving roadway, it is divided into raise boring machine, shaft boring machine and drift boring machine
① raise boring machine is specially used for drilling raise and pass. Generally, it doesn't need to enter the raise for operation. The guide hole is drilled with a cone bit, and the hole is enlarged upward with a reamer composed of disc hobs
② the vertical drilling rig is specially used for drilling a well at one time, which is composed of drilling tool system, rotary device, derrick, drilling tool lifting system and mud circulation system
③ drift digger is a comprehensive mechanized equipment which combines mechanical rock breaking and slag removal and continuously dries. It is mainly used for tunneling in coal roadway, engineering tunnel in soft mine and middle drift with medium hardness and above
the special dryer for slime is a new type of special drying equipment developed on the basis of drum dryer, which can be widely used in the drying of slime, raw coal, flotation clean coal, mixed clean coal and other materials in coal instry
2. Drying of blast furnace slag, clay, bentonite, limestone, sand, quartzite and other materials in construction instry
3. Drying of various metal concentrates, waste resie, tailings and other materials in mineral processing instry
4. Drying of non heat sensitive materials in chemical instry
reces the risk of clearing and settlement of foreign exchange transactions
clearing and settlement is an important part of foreign exchange transactions, and the development of information technology has innovated the clearing system of the global foreign exchange market. In view of the interrelationship of the financial system, the liquidation failure of a large transaction will trigger a series of defaults. The risk is that the cross-border settlement of funds is only carried out ring the normal working hours of the Central Bank of the home country, while the two clearing parties may be in different time zones. If one party of foreign exchange transaction settles before the other party, the party waiting for the other party's settlement will face the risk of default of the counterparties. If a foreign exchange trader makes a transaction and pays the e currency but does not get the e currency at the same time, the foreign exchange trader will face the loss of exchange rate change or losing the e currency. The risk comes from the asynchrony of payment
in essence, blockchain is an information technology solution to solve the trust problem and rece the trust cost, which can ensure the integrity of data without credit accumulation, because all these data are recorded on the tamper proof blockchain, so the complicated steps of centralized verification of ID card are omitted in foreign exchange transactions, and the whole process is completely transparent, And tracking is very safe and easy, which can help brokers speed up the clearing and settlement of the transaction, and greatly rece the transaction risk
improve transaction efficiency and rece costs
the general process of foreign exchange transaction is that one party of the transaction transfers the capital to an intermediary, such as CLS, which will hold the capital of the original party until the counterpart provides the capital. The problem with this process is that the funds of the first party will be frozen in a specific transaction before the settlement is completed, and the whole process often takes one day. This leads to slow trading in the foreign exchange market
regional chain technology can make foreign exchange transactions faster and cheaper. Because of the transaction mode based on regional chain technology, there is no central organization or central server. All transactions take place in the client application installed on everyone's computer or mobile phone, which directly saves the commission cost or intermediate handling fee of the transaction. Whether it is cross-border transfer or domestic transfer, this decentralized approach not only reces transaction costs, but also improves transaction speed
enhance the security of foreign exchange trading
the average daily trading volume of the global foreign exchange market is as high as 6 trillion US dollars, and the stability and security of the system is very important for such a huge foreign exchange trading market with daily throughput
blockchain has a natural security defense mechanism. Because each data block contains all the information exchange data of the system in a certain period of time, and it is encrypted with the method of cryptography, which eliminates the security vulnerability from the beginning. When a transaction occurs, miner in the blockchain network uses the algorithm to decrypt and verify the transaction, creating a new data block record, which will be placed at the end of the previous data block and continue to spread
the whole process must be completed through complex digital signature, digital signature algorithm and computational verification. Each data block is continuously recorded in the verification process, and each node can be tracked. So that foreign exchange transactions can be completely transparent, traceable transaction process, and its stability and security is more reliable than before. Some data show that even if the blockchain is attacked, the attacker can only tamper with the information by breaking through more than 51% of the nodes. However, in a blockchain system large enough, the cost is extremely high, which can be considered as basically impossible
provide convenience for foreign exchange supervision
the main trading mode of foreign exchange market is OTC (over the counter, also known as OTC). The international nature of the trading boundary means the lack of centralized and unified regulatory agencies, so the supervision of foreign exchange trading has always been a difficult problem for the instry
as an underlying technology, the application of blockchain is not only digital currency. In this aspect, we can combine the technical characteristics of blockchain to empower enterprises and instries.
you must be familiar with bitcoin now. The virtual currency, once considered as a freak, has flourished in the economic market. In particular, bitcoin once caught fire in the past two years, attracting countless people who fantasize about huge wealth to pursue. Recently, Libra, another virtual currency, has emerged. What will be the future market of Libra, Will it bring an explosion to the economic market just like bitcoin
{rrrrrrr}
from the original intention of creating Libra coin is to save money for users, this original intention will certainly be recognized by everyone, but the key to the future direction of Libra coin is how to solve the operation supervision problems in the later stage. Bitcoin once panicked bitcoin holders because of security problems. The market of virtual currency is global. It is a great challenge for operating companies to do a good job in global security supervision. I also hope that Libra coin can grow up and fight against bitcoin. After all, the more competition, the more our interests will be maximized
