Statistics show that in the past year, the whole province has organized and carried out rectification actions for several times, including putting on file and investigating cases of violation of laws and regulations on mineral resources, carrying out appraisal of the value of mineral resources, and investigating the criminal responsible persons according to law. Through centralized rectification, the phenomenon of mass indiscriminate mining has been basically eliminated, and the mining order and environment of some key and difficult mining areas have undergone tremendous changes, The order of mineral resources development in the whole province has improved significantly. Meanwhile, the whole province has jointly investigated and dealt with mine entrepreneurs who have seriously polluted the environment. All proction mines in the province have carried out mine geological environment restoration and treatment according to the requirements. A total of mine geological environment monitoring points have been built, and dynamic inspections of mine geological environment protection have been carried out, It has effectively alleviated the geological environment and safety problems brought about by mine development. There are six mining areas in the whole province that have carried out resource and deep integration in this round. They have participated in the integration of the double counterweight wheel device, made full use of the inertia principle to protect the crusher, greatly improved the operation level of the crusher, and made the maintenance easier, the operation more convenient, and the downtime shorter; The machine can stabilize the equipment and discharge materials normally in case of large materials, greatly recing the problem of low output caused by unstable operation of the machine. The cinder crusher adopts hydraulic adjustment, thin oil lubrication and effective labyrinth sealing, The common faults such as oil-water mixing of cinder crusher are eliminated fundamentally. The crushing wall and bearing wall of cinder crusher are made of high manganese steel. Due to the change of crushing cavity, the wear is reced, and the general service life can reach more than 30000 tons. It provides higher proction capacity, the best proct particle shape, and is easy to automatic control, with maximum reliability and flexibility, It really creates more value for users. Due to the optimized design and hydraulic protection of the crusher, the failure rate of the equipment is greatly reced. Under normal use, the failure free operation rate of the equipment will exceed that of the world. China is a responsible country, We can no longer seek high-speed economic growth through the uncontrolled emission of the pulverizer. Our development is not complete. The sustainable development of the cinder pulverizer can only take the road of energy-saving, green, low-carbon and sustainable development, After entering between the grinding roller and the ring, it is crushed by rolling. The fan blows the air into the grinding chamber, and then the powder is blown into the analyzer for separation. If the fineness is not reached, it falls into the grinding chamber again. The qualified fine powder enters the finished proct cyclone powder collector with the air flow. After the fine powder and air are separated, it is discharged from the discharge port to be the finished proct, and the air returns to the fan from the upper return air pipe, In addition, it flows in the grinding chamber of the ultra-fine grinding machine under negative pressure. Due to the certain water content of the material to be grinded, certain heat will be generated ring grinding, resulting in water vapor evaporation, and the external gas will be inhaled e to the loose connection and sealing of each pipe flange of the whole machine, which will increase the amount of circulating air flow, The increased air flow is discharged into the bag filter through the resial air pipe between the fan and the main engine, and is discharged into the air after being purified
the lower two sets of rotors have flywheels, which can adjust the periodic speed fluctuation of operation to make the operation uniform and stable, increase inertia, overcome movement resistance, save power, centralized lubrication system, and inject oil without shutdown, It is convenient and fast. The whole machine can fill all bearings with lubricating oil at any time under the working state of the machine. It is simple, convenient, safe and reliable, and easy to maintain the cinder in daily life. The cinder is discarded for a long time, which not only occupies a large area of land, It is harmful to human life and proction. Coal cinder is easy to pollute the soil. The harmful components in coal gangue penetrate into the soil through the erosion of weathered rainwater surface runoff, resulting in soil acidification and salinization, making the land very barren, which is not concive to farming. At the same time, it also destroys the growth of microorganisms in the soil, The coal cinder crusher developed by Quanxin machinery is a typical equipment for crushing hard ores in China.

3. Edison only went to primary school for three months in his life. His knowledge came from his mother's teaching and self-study. His success should be attributed to his mother's understanding and patient teaching since childhood, which made Edison, who was originally regarded as an incompetent child, become a world-famous "king of invention" when he grew up
Edison was curious about many things since he was a child, and he liked to experiment with them himself until he understood the truth. When he grew up, he devoted himself to research and invention according to his own interests. He set up a laboratory in New Jersey and invented more than 2000 kinds of things in his life, such as electric lamp, telegraph, phonograph, video camera, magnetic separator, crusher and so on. Edison's strong research spirit made him make great contribution to the improvement of human life style
"waste, the biggest waste is to waste time." Edison often said to his assistant“ Life is too short. Think more and do more with less time. "
one day, Edison was working in the laboratory. He handed his assistant an empty glass bulb without a light port and said, "you measure the capacity of the bulb." He bowed his head to work again
after a long time, he asked, "what's the capacity?" He didn't hear the answer. He turned his head and saw his assistant measuring the perimeter and inclination of the bulb with a tape measure. He took the measured number and put it on the table to calculate. He said, "time, time, how do you spend so much time?" Edison came over, picked up the empty light bulb, filled it with water, handed it to his assistant, and said, "pour the water in the measuring glass, and tell me its capacity right away."
the assistant immediately read out the number
Edison said, "what an easy way to measure. It's accurate and time-saving. Why can't you think of it? Is it not a waste of time? "
the assistant blushed
Edison murmured: "life is too short, too short. Save time and do more things!"< Before he became famous, Edison was a poor worker. Once, his old friend met him in the street and said with concern, "look, this overcoat on you is not in good condition. You should replace it with a new one."
"do you need it? No one knows me in New York Edison answered with indifference
a few years later, Eddie has become a great inventor< One day, Edison met his friend on the street of New York“ "Oh," exclaimed the friend, "Why are you still wearing this old coat? This time, you need a new one anyway
"do you need it? Everyone here already knows me. " Edison still answered with indifference.

7. Cherish time ~ ~ ~
time is the material of one's life. " Everyone's life is limited, and the time that belongs to a person is also limited. If a person's life is at the end of his life, then his life is over. It can be seen that people are closely related to time

among all the critics in the world, time is the greatest, the most correct and the most gifted, while time is also the fastest, the slowest, the longest, the shortest, the most ordinary and the most precious, the most easily neglected and the most easily regretful in the world

the poplar is withered, and it will be green again; A hundred flowers are gone, and they will bloom again; Swallows have gone and come again; However, a person's life is suffocated, but there is no chance of resurrection. As there is such a saying: "flowers bloom again, no one is young." Time is the same, step by step, step by step, never stop, never return

since ancient times, many people have regretted that time is fleeting, so they lament that "time is fast, life needs to be timely", "the water of the Yellow River comes up from the sky, runs to the sea and never comes back..." indeed, the speed of time is really unpredictable and indescribable. So, how can one live a more meaningful life and make e contributions in his lifetime? That's why we should cherish our short time. The ancients have a poem: "three lights, five chickens, it is a man reading, black hair do not know diligent early, white party regret late reading."“ "Young people don't work hard, old people are sad" and other poems are warning people: life is limited, we must cherish time like gold, never waste precious time, but take advantage of youth to learn more and do more career

to cherish time is to cherish one's own life. Since ancient times, no one who has made great achievements has not cherished time. Edison, the great inventor, had an invention in three days on average. He grasped every minute and studied it carefully. He did more than 1000 experiments just to find out what materials to use for making electric filament. Lu Xun, a great writer, has a saying: "where is genius, I spend other people's coffee time on work." He left us more than six million words of spiritual wealth, just because he spent other people's coffee time writing. Mathematician Chen Jingrun, day and night, devoted himself to the study of mathematical problems -- Goldbach conjecture. There are several sacks in the draft of calculus alone, but he finally proved this problem and took off the crown of mathematics. Marx, the revolutionary mentor of the proletariat in the world, wrote Das Kapital against the clock before he died. These examples are vivid. He shows that if one wants to make some contribution in his lifetime, he must cherish his time< According to Shakespeare's famous words, "he who gives up time, time will also give up him." "time will break through the magnificence and delicacy of young people, and it will engrave parallel lines on the forehead of beauties; It will eat rare treasures, natural beauty, nothing can escape its sweeping sickle This also strongly shows that in order to achieve success, we must cherish time<

Da Vinci, an outstanding Italian painter, said: "if you work hard for one day, you can have a good night's sleep; If you work hard all your life, you will be happy forever. " Leo Tolstoy's maxim "the time you let go without using it effectively can never be returned.". And Darwin said, "how can you do so many things in your life?" He replied, "I never thought half an hour was a small time." How can these famous sayings, aphorisms and live sayings not tell people profoundly that many people who have made achievements and achievements have achieved results by cherishing time, and they have spent their youth with the magic method of cherishing time

however, there are still a few of us who can't learn from the lessons of our predecessors. They don't cherish time, they are mediocre and do nothing; They put what they want to do today to do tomorrow. They are born in wasted time. They don't feel regret for wasting time or shame for doing nothing; They may sece others, wander around and waste other people's time; They may play hard ring the day and drive late at night, which not only can't cherish time, but also affects people's physical and mental health

time is like running water, fleeting; Life is like a laser. In a letter to the youth, Pavlov said: even if a person has two lives, it is not enough for us young people. Comrade Dong Biwu's poem to "middle school students" reads: "it's a pity for the ancients to say that sailing against the current, trying hard to prop up, one pole slacking, and retreating a thousand times. We should cherish the second Yin." They all remind us that we should cherish our time. Today, on the road of our progress, there are two mountains, Taihang and Wangwu, which are difficult and foolish. To remove these two mountains, we should speed up the pace of time, seize the reins of time, and lift the belated "future" onto the horse's back. Let it put on its wings and bring wind to our feet! You have to believe that the future comes slowly, the present flies like an arrow, and the past never moves“ Every inch of time is worth every inch of money, and every inch of money can't buy every inch of time. "Time is equal to everyone. It doesn't give more because you are diligent, and it doesn't give less because you are lazy. But in this limited time, people with different ideas will get different results

as young people in the 21st century, are we not as good as the ancients? We have ideals and confidence. We should strive to learn scientific and cultural knowledge and devote our youth to the four modernizations. We should cherish time more because time is the material of one's life.

the assistant blushed

all those who have made great achievements at all times and in all over the world are as good as gold at all times. The ancient book Huainanzi says: & quot; Sages do not value the wall of the ruler, but the Yin of the inch& quot; There is such a poem in changgexing, the Yuefu of Han Dynasty: & quot; When will all rivers return to the sea? If you don't work hard when you are young, you will be sad when you are old& quot; In Jin Dynasty, Tao Yuanming also had his poems of cherishing time: & quot; If you don't make a comeback in the prime of life, you can't make it in the morning. Just in time, you should be encouraged, and time will wait for no one& quot; In the late Tang Dynasty, Wang Zhen's poem "White Deer Cave" has more & quot; An inch of time is an inch of gold; It's a wonderful metaphor. Balzac, a French writer, compares time to capital. Goethe, a German poet, regards time as his own property. Lu Xun has a deeper understanding of time. He said: & quot; Time is life. Wasting other people's time for no reason is tantamount to murder& quot; After middle age, in order to save time, Faraday devoted his whole body and mind to scientific creation, strictly controlled himself, refused to participate in all activities unrelated to science, and even resigned as the president of the Royal College. Madame Curie never put a chair in the drawing room so as not to delay the visitors. Einstein, 76, fell ill. An old friend asked him what he wanted. He said, "I just hope there are still a few hours left for me to sort out some manuscripts.".

Thomas Alva Edison (1847-1931) was a famous American inventor and entrepreneur
born on February 11, 1847 in a peasant family in Milan, Ohio, USA. When he was 8 years old, he went to school. After only three months of study, he had to drop out of school and go home. His mother, who was a village teacher, helped him to study by himself. At the age of 12, the family life was difficult, so they began to sell newspapers on the train. At the age of 16, they invented the automatic time transmitter, and then there were many inventions. They completed more than 2000 inventions in their lifetime. In 1928, they were awarded the US Congress gold medal. On October 18, 1931, Edison died in West Orange at the age of 84. On October 21, 1931, the lights were turned off in the United States to show his mourning. Scientific achievements

Edison is a world-famous great inventor. The invention of his life is unparalleled in the world. Edison's main contributions are as follows:
1. Edison's most important contribution in science and technology is the invention of phonograph and incandescent lamp. Today, it's hard to imagine life without electricity - unable to turn on a light, listen to a record, go to the cinema, or call someone. However, all these things we take for granted are the result of a practical invention - Thomas Edison. Before Edison, on the road, in the living room, in the factory, can only use by hand lit dim gas lamp. As night fell, factories closed. Electricity or the telephone was not invented by Edison. But his practical invention and improvement pushed the use of electricity and telephone to every corner. Edison was perhaps the greatest inventor ever. He was the pioneer of technological innovation in the modern world. This tireless inventor brought us from the steam age into the 20th century< Edison also made many famous inventions in film, tram, mining, architecture and weapons< The discovery of hot electron emission laid the foundation for the development of electron tubes, Thomas Alva Edison was born in Milan, Ohio in 1854. His family moved to Port Huron, Michigan. Soon Edison got scarlet fever and was seriously ill. This serious illness became the main cause of his later deafness< In 1855, Edison studied in ingel school for three months< In 1859, at the age of 12, Edison became a newsboy on a Detroit train in Port Huron< The civil war broke out in 1861 and the battle of Shiloh in 1862; In 1863, at the age of 16, Edison became a newspaperman. Later, he wandered around and worked as a newspaperman.
in 1868, Edison arrived in Boston and found a job in the United Telegraph Company. He applied for the first patent (voting device), and the news of his two-way telegraph was published in the magazine of the telegraph operator< In January 1869, Edison became a free inventor.

Edison is a world-famous great inventor. The invention of his life is unparalleled in the world. Edison's main contributions are as follows:
1. Edison's most important contribution in science and technology is the invention of phonograph and incandescent lamp. Today, it's hard to imagine life without electricity - unable to turn on a light, listen to a record, go to the cinema, or call someone. However, all these things we take for granted are the result of a practical invention - Thomas Edison. Before Edison, on the road, in the living room, in the factory, can only use by hand lit dim gas lamp. As night fell, factories closed. Electricity or the telephone was not invented by Edison. But his practical invention and improvement pushed the use of electricity and telephone to every corner. Edison was perhaps the greatest inventor ever. He was the pioneer of technological innovation in the modern world. This tireless inventor brought us from the steam age into the 20th century< Edison also made many famous inventions in film, tram, mining, architecture and weapons< The discovery of hot electron emission laid the foundation for the development of electron tubes, Thomas Alva Edison was born in Milan, Ohio in 1854. His family moved to Port Huron, Michigan. Soon Edison got scarlet fever and was seriously ill.
