Schematic diagram of ESHI crusher mechanism

1. Eth is Ethereum and Zec is zero

2. 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. Jaw crusher or choose casting structure, the quality is more reliable, more cost-effective. Shandong Ruilong's casting jaw crusher procts cover many provinces and regions in China, and the export volume is also quite large. I suggest you go to the manufacturer and compare the manufacturer with the proct.

4. The length of tension adjusting spring of Nanchang mining machine hook C 1000 jaw crusher is 20

5. According to the way of crushing force, crushers can be roughly divided into two categories: (1) crushers: crushers generally deal with large pieces of materials, and the proct size is coarse, usually greater than 8 mm. Its structural feature is that there is a certain gap between the broken parts and they do not contact each other. Crusher can be divided into coarse crusher, medium crusher and fine crusher
(2) grinding machine: Generally speaking, the material processed by the grinding machine is fine, and the proct size is fine, up to 0.074 mm, even finer. Its structural feature is that the crushing parts (or medium) contact each other, and the medium used is steel ball, steel bar, gravel or ore block. But some machines have the function of crushing and grinding at the same time, such as autogenous mill. According to the crushing mode and mechanical structure characteristics (working principle), the crushers can be divided into six categories:
(1) jaw crusher (tiger mouth): the crushing action is to press the movable jaw plate to the fixed jaw plate periodically to crush the ore block 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) impact crusher: it uses the high speed impact of the plate hammer and the rebound effect of the impact plate to make the material receive repeated impact and crush. The plate hammer is fixed on the high-speed rotating rotor, and several impact plates are arranged at different angles along the crushing chamber
(4) 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
(5) 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
(6) 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
(7) other types of crushing mills: A. roller mills: grind materials by rotating rollers. B. Disc mill: the disc rotation of vertical axis or horizontal axis is used as crushing part. C. Centrifugal mill. High speed rotating parts and medium are used to proce centrifugal force to complete crushing. D. Vibration mill. High frequency vibration is proced by the rotating shaft, which makes the medium and material collide with each other to complete the crushing effect
in order to check and understand whether the technical operation of each proction link meets the process requirements; In order to provide the managers and technicians of the concentrator with the weak links in proction, find and solve the problems in time, and promote the normal proction, the technical detection plays an indispensable and decisive role. It is an important means to do well in proction technology management, metal balance and management level. Therefore, each concentrator must carry out a series of proction technology testing work, and set up corresponding organizations according to the specific situation, such as quality management materials, technical inspection department, technical supervision station, testing group, etc From: Henan Zhenping Xinlong Machinery Manufacturing Co., Ltd.)

6. It can be divided into six categories according to the crushing mode and the structural characteristics of machinery (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

7. There is no strict anti-counterfeiting label for coins. The main way to identify the authenticity of coins is to see that the teeth of coins are neat and uniform, the font is clear, the level is clear, the pattern is beautiful, and the overall layout is like a work of art
for example, 50 cents coins: on June 1, 1992, the people's Bank of China issued the third set of metal currency under the fourth set of RMB, with a face value of 10 cents, 5 cents and 1 yuan. 1 yuan is the peony pattern, 5 cents is the plum pattern, and 1 jiao is the chrysanthemum pattern. Among them, the plum blossom 5-dime coin was issued again after the issue of copper alloy Great Wall coin (1,2,5 Jiao, 1 yuan) from 1980 to 1986. It is made of copper zinc alloy, golden in color, well-designed and made, beautiful and generous. It is commonly known as "plum blossom 5-dime" coin
there are 11 pieces of plum blossom 5 jiao coins from 1991 to 2001, with a diameter of 20.50 mm, a thickness of 1.65 mm and a mass of 3.80 G. On the front of the coin is a plum blossom pattern with a face value of & quot; 5 jiao & quot; (& quot; 5" It is a hollow character with horizontal lines in it& quot; 5" Large, & quot; Angle & quot; Smaller, & quot; Angle & quot; The Chinese Phonetic Alphabet & quot; WUJIAO" There are 6 straight teeth on the cylindrical surface of the coin, 8 in each section. There is a circle of dots in the outer edge, which makes the coin face more beautiful. On the back are the national emblem, song Chinese characters "the people's Republic of China", "Zhonghua Renmin Gongheguo" and Arabic numerals

8. C RMB or US dollar can be used as bookkeeping base currency, and RMB should be used for accounting statements. I don't know how to choose the questions. For reference only.

9.

First of all, when you see the news, you still have a lot of background knowledge to learn

Offshore RMB refers to the circulation market formed outside China when the RMB that flows out of RMB settlement business can not enter the Chinese market. Offshore RMB 6.4195 to us dollar means that one US dollar can be converted into 6.4195 RMB in offshore RMB market But the domestic exchange rate may be different)

the rise of offshore RMB against the US dollar does not mean the depreciation of the US dollar. It may be the unilateral appreciation of RMB (because the IMF's vote on RMB joining the SDR will be announced later)

the offshore RMB rose to 0.44% against the US dollar because it should be regarded as a kind of correction because it fell a lot before. Generally speaking, the US dollar is on the way of appreciation, while RMB is on the way of depreciation< br />
