Monroe, based on the historical experience of Greece, Germany and other countries, opposed the "excessive concentration" of the federal government's power at the meeting to discuss the ratification of the constitution. He said that if power is too concentrated, there will be sharp conflicts between the state government and the federal government. He firmly opposed the president's tenure and advocated the holding of regular elections
since 1787, the United States has split into two different political factions on the issue of ratification of the constitution. Monroe actively supported the bourgeois Democrats led by Jefferson and opposed to the ratification of the constitution, which was called the anti Federalist party at that time, and opposed the bourgeois conservatives led by Hamilton and supported the ratification of the constitution, which was called the US Federal Party at that time< In 1794, the relationship between the United States and France became tense. In order to show goodwill to France, Washington government appointed Monroe as minister to France. After Monroe went to France, Monroe made a passionate and generous speech against tyranny and supporting the French Revolution, and then convinced the French government to release the famous American Revolutionary Thomas Paine and the wife of French revolutionary Lafayette.

Here, he became a real homeless man. On July 4 of that year, he died of heart failure at his daughter's home. At the age of 73, he became the third former president to die on national day
income have grown twice as fast as its per capita GDP. The Russian people have enjoyed the fruits of economic growth. At present, the average monthly wage of Russians is 10800 rubles, about 3650 yuan. Among them,
Moscow has the highest per capita wage, which is about 20000 rubles, equivalent to 6700 yuan; The Far East, bordering China, has the lowest monthly wage, ranging from 9500 to 10000 rubles (3200 to 3360 RMB)
the growth rate of real wages is much faster than that of GDP, which is just one aspect of the economic growth fruits shared by Russians. On the other hand, the Russian Federation, the main bodies of the Federation and the local governments spend one third of their fiscal expenditure on ecation, medical care, relief and other social fields. So as to establish and maintain a perfect social welfare system. Let the retired, unemployed, children, students and other vulnerable groups also share the fruits of economic growth in a down-to-earth way
with economic growth, every quarter in Russia adjusts the "minimum living standard per capita", that is, "poverty line". The minimum standard of living is set by the main bodies of the Russian Federation every quarter, which is used to assess the living standards of residents and
as the funds for formulating subsidies, compensation and other social security payments. In the third quarter of this year, the minimum living standard per capita in Moscow is 5124 rubles per month (equivalent to 1700 yuan per month in Beijing, since July 1, 2006, the basic cost of living is 448 yuan per person per month, which is only 26% of the minimum living standard in Moscow). The minimum living standard of residents with working ability is 5795 rubles, that of retirees is 3533 rubles, and that of children is 4381 rubles. In the second quarter of this year, the minimum living cost per capita of residents in Binhai border areas bordering Northeast China was set at 4362 rubles per month (equivalent to 1450 RMB per month), and the current minimum living cost guarantee standard of residents in Harbin city of Heilongjiang Province was set in 1997, with 200 RMB per person per month and 117 RMB per person per month in Acheng City, Shang City, Mulan county and Yanshou county, The lowest cost of living index of residents with working ability was rub
4687, rub 3383 for retirees and rub 4202 for children. As the standard of "poverty line" is particularly high, it is equivalent to 40% of per capita GDP in the average calculation of Russia, and the largest part of government expenditure at all levels is used in social security systems such as health care, ecation, subsidies and relief. Taking the children's subsidy project in 2007 budget of Moscow as an example, the total amount of social support for families with children is 36 billion rubles (10.8 billion yuan) in the city's budget next year, and the one-time subsidy for families with two or more children will increase four times, ranging from 2000 to 10000 rubles; The amount of monthly allowance for each child will increase 1-1.5 times; The annual school uniform subsidy for families with many children increased from 1000 rubles to 5000 rubles
parents who are unable to go out to work e to taking care of disabled children under 3 years old at home will receive 4500 rubles (1300 RMB) per month; The monthly food subsidy of College Students' families raising children under three years old will be tripled, from 550 rubles to 1650
rubles; In order to prevent the emergence of social orphans and develop family ecation methods, the amount of money granted to guardians for raising their ward will be increased from 4500 rubles to 6000 rubles Note: the latest exchange rate is 10 rubles = 2.9731 RMB)
it can be said that in today's Russia, "poverty" is relative, in an absolute sense, there are no poor people. Elected officials try their best to please the voters. In addition to free medical care and ecation, there are hundreds of Russian government subsidies and relief projects. In such a situation, it is not easy to be a poor man in a recovering Russia. On April 10, Russian finance minister Kudrin announced that according to Russia's 2007-2009 three-year budget plan, real wages will increase by 50% in the next three years. Russia's macroeconomic analysis and short-term forecast center's report "Russia's long-term economic trend" predicts that by 2012, Russia can enter developed countries and catch up with the economic development level of South Korea, Spain and Israel. By 2020, the per capita GDP will reach 29400 US dollars
after 15 years of transformation, the Russian people have truly realized the Centennial dream of humane and democratic socialism.
The maintenance of the machine is an extremely important and regular work, which should be closely coordinated with the operation and maintenance of the machine. There should be
full-time personnel on ty for inspection. 1. The equipment should be installed on the horizontal concrete foundation and fixed with anchor bolts
2. Pay attention to the perpendicularity between the main body and the horizontal when installing
3. After installation, check whether the bolts at all parts are loose and whether the main engine compartment door is tight. If so, please tighten it
4. Configure the power line and control switch according to the power of the equipment
5. After the inspection, the no-load test run is carried out, and the proction can be started when the test run is normal. 1. The bearing bears all the load of the machine, so good lubrication has a great influence on the bearing life, which directly affects the service life and operation rate of the machine. Therefore, the injected lubricating oil must be clean, and the seal must be good. The main oil injection place of the machine (1) turns
moving bearing (2) roll bearing (3) all gears (4) movable bearing Sliding surface.
2. The newly installed tyre is easy to loose, so it must be checked frequently.
3. Pay attention to whether all parts of the machine work normally.
4. Pay attention to the wear degree of easily worn parts, and pay attention to replacing worn parts at any time.
5. Place the underframe plane of the movable device, Dust and other materials should be removed to prevent the movable bearing from moving on the underframe when the machine encounters materials that cannot be broken, resulting in serious accidents.
6. When the bearing oil temperature rises, stop the machine immediately to check the cause and eliminate it
7. If there is impact sound when the rotating gear is running, stop the machine immediately to check and eliminate it. Compared with jaw crusher, rotary crusher has the following disadvantages:
1. The structure of rotary crusher is complex, manufacturing is difficult, and the price is higher, which is much more expensive than jaw crusher with the same feeding mouth< The weight and height of the machine are 1.7-2 times and 2-2.5 times higher than the jaw crusher with the same feeding mouth, so it needs a higher plant, so the construction cost of the plant is also high
3. The installation and maintenance are complicated, and the overhaul is also troublesome
4. For the treatment of ore with more mud and viscosity, the ore outlet is easy to be blocked, the crushing cavity is deep, the work is continuous, the proction capacity is high, and the unit power consumption is low. Compared with the jaw crusher with the same width of feeding mouth, its proction capacity is more than twice that of the latter, and the power consumption per ton of ore is 50% - 80% lower than that of the jaw crusher. The work is stable, the vibration is light, and the foundation quality of the machine is small. The foundation quality of gyratory crusher; It is usually 2-3 times of the mass of machinery and equipment, while the basic mass of jaw crusher is 5-10 times of the mass of the machine itself. It can be filled with ore, and large-scale rotary crusher can directly feed raw ore without adding ore bin and feeder. The gyratory crusher is easy to start without flywheel and other auxiliary tools. Now the advanced large-scale gyratory crusher can start with full bin and load. The flake procts proced by the rotary crusher are less than those proced by the jaw crusher. The initial cost is high, but in the long run, the overall benefit is higher than jaw crusher
