1. Let's say, is bmex a regular contract exchange
the survival of the fittest in the financial market, survival of the fittest, and the disappearance of the pheasant exchange can make a stronger exchange stand. As the top of the coin circle food chain, the security and operation problems of the exchange will cause the exchange to run away. The real losers are also innocent investors. Xiong Da said that without a real bull market, it is difficult for the bear exchange to survive in this market. That's why investors are not advised to trade on small exchanges. Below Xiong Da sorted out the recently written running pheasant exchange<
Li Ming, founder of bitgogo exchange, forcibly freezes investors' digital asset management. The reason given is that in view of the large fluctuation of the current market and the long-term stable development of the exchange, in order to maximize the ability to protect the safety of users' assets, some mainstream assets of investors will be directly frozen for 180 days. This is the overlord clause. This is to make more money before running. In addition, the IEO projects launched in recent years have directly returned to zero<
"shangcoin" exchange
shangcoin exchange said that it has won tens of millions of strategic investments such as bhex ecological investment fund, hkdt ecological investment fund, Xingyao capital, vector capital, Lishi fund and imagination fund founded by jujianhua, a well-known investment institution. It claims to have thousands of futures market employees, and strategically cooperates with dozens of digital asset contract communities and hundreds of contract KOLs. If you are familiar with the "futures contract" in the traditional financial field, you will not be unfamiliar with the "perpetual contract" in the field of digital asset investment.

2. Many of the lining plates of crushers are made of high manganese steel
the lining plates of jaw crusher, impact crusher, heavy hammer crusher and box crusher are made of rigid manganese steel

the replacement cycle of crusher lining plate
when replacing the frame lining plate, if the old lining plate can't be removed, gas welding can be used to cut and clean the inner surface of the frame. The newly cast concrete on the back of the lining plate is mixed with 500-600 cement and sand in the ratio of 1:3 by weight. Before casting, the lining plate should be polished to make the concrete firmly combined with it
after the concrete is poured, it must be trimmed to make the reinforcement on the back of the lining plate close to the frame, and it must be put into use after the concrete is fully cured and dried, otherwise the service life will be affected
replace the broken cone liner: when the liner at the lower part of the cone is installed, use the adjusting ring at the lower part of the cone to keep a gap of 1.0 ~ 2.0 mm between the liner at the lower part and the cone. After the top liner is installed, the compression nut shall be installed first, and then the zinc alloy shall be cast. Before casting, the cone and liner should be preheated for 60-80 ℃, and the joints of liner should be plugged with asbestos and clay to avoid leakage of zinc alloy. After pouring the alloy into the lining plate, install the compression nut and locking plate to fix it tightly
in order to further expand proction. The crusher accessories must be maintained and registered for use. Only in this way can the monitoring and stability of the working state of the crusher be fundamentally completed.

6. The fixed jaw liner (toothed plate), moving jaw liner (toothed plate) and two side liner (guard plate) of jaw crusher are the most easily worn. After serious wear, the particle size of the proct becomes larger. In case of initial wear, the toothed plate can be used for U-turn, or the upper and lower parts can be used for U-turn. The wear of jaw plate is mostly in the middle and lower parts. When the tooth height is worn out by 3 / 5, a new lining plate is needed. When two fifths of the lining plates on both sides are worn out, they also need to be replaced with new ones.
7. When the liner thickness is worn by two-thirds, or is worn out or cracked, or the discharge port is too large to be adjusted, the liner needs to be replaced. Different replacement ranges can be determined according to the wear and fracture conditions:
(1) the frame and crushing cone liner need to be replaced at the same time
(2) replace only one of the frames or crushing cones and all the lining plates
(3) only replace the frame and crush the lower liner of the cone
(4) only replace the lower liner of one of the frame or crushing cone
(5) only partial replacement
when replacing the frame liner, if the old liner can not be removed, gas welding can be used to cut and clean the inner surface of the frame.

8. It may be that the size of the lining plate is wrong or the installation is wrong. The specific reason is to find a professional to have a look
in addition, the crusher generally uses wear-resistant lining plate and high-strength wear-resistant steel plate, such as jfe-c400, dillir 400V, etc.

9. When the liner thickness is worn by two-thirds and there is no wear leakage or fracture, or the discharge port is too large to be adjusted, the liner needs to be replaced. Different replacement ranges can be determined according to the wear and fracture conditions:
1. Replace all the frame and crushing cone liners at the same time
2. Replace only one of the frames or crushing cones and all the lining plates
3. Only replace the frame and crush the lower liner of the cone
4. Only replace the lower lining plate of one of the frame or crushing cone< 5. Only partial replacement
when replacing the frame liner, if the old liner can not be removed, gas welding can be used to cut and clean the inner surface of the frame. The newly cast concrete on the back of the lining board is mixed with 500-600 cement and sand in a mass ratio of 1:3. Before casting, the lining plate should be polished to make the concrete firmly combined with it
after the concrete is poured, it must be trimmed to make the reinforcement on the back of the lining plate close to the frame, and it must be put into use after the concrete is fully cured and dried, otherwise the service life will be affected
when replacing the crushing cone liner, do not damage the cone in the process of cutting the liner. When the lower lining plate of the cone is installed, use the adjusting ring at the lower part of the cone to keep a gap of 1-2mm between the lower lining plate and the cone. After the top liner is installed, the compression nut shall be installed first, and then the zinc alloy shall be cast. Before casting, the cone and liner should be heated for 60-80 ℃, and the gap between the joints of liner should be plugged with asbestos and clay to avoid leakage of zinc alloy.
