Ni paulownia wood, 1900 was born on January 16, Songjiang County, Shanghai, childhood out in the imperialist "concessions" could not bear to see a lot of things to see. When the Japanese invasion of Shanghai, home destroyed in the enemy's shells, the saving from childhood, power of desire. Northern Tianjin University in 1918 obtaining matriculation classes, determined to save the country industry. 1924 cum laude graduate of Mining and Metallurgy, Department of limited financial difficulties, give up the opportunity to study abroad in Shanghai, the public donated patrol bureau office warehouse rather Motors three years later, to any coal mine in Tangshan Kailuan division. Kailuan coal mine in 11 years, he often go to mine, to master the law of the coal seam characteristics and output, flexible use of various mining methods and equipment, effective organization of coal mining. After the outbreak of war, for national survival, he decided to abandonment westward to the development of new mines, coal mines have to build Yiluo Henan, Hunan Enhong mine. After the war the south because of Guangxi, Guangxi Bureau of Mines at the level of resources survey and smelting in the work.
In 1941, afraid of hard Ni paulownia wood safety, border town to the motherland, the world-famous tin production powerhouse - old, hard-working, contributed to the development of Tin's own life. Began his employment as a factory manager selection old, part-time new plant in 1945, and tin Kuangkuang Chang, director of public works in 1946 and was appointed chief engineer of Yunnan Tin Co., Ltd.. In the same year, Ni paulownia wood to go to London, England in the World Tin meeting, and to Canada, the U.S. investigation, joined the American Mining Association. In other countries, see the still in its infancy, several new mineral processing equipment, back to Yunnan Tin Co., Ltd., he was determined to change the old situation behind indigenous beneficiation of mineral processing equipment, a reform process, much has been achieved attracted the attention of international mineral processing industry. However, behind the chaotic social environment, limiting the play of his intelligence. Numerous grim fact that he recognized the KMT's corruption. His sympathy, support progressive forces and the Chinese Communist Party. In December 1949, when Nationalist troops retreat old, he co-Lu Mian Yunnan Tin Co., Ltd. Associate effectively resist the KMT South Eighth Army, twenty-sixth military harassment of Yunnan Tin Company Limited damage, with the underground Communist Party and the People's Liberation Army, intact, Yunnan Tin Co., Ltd., ushered in the Yunnan tin mine life.
After the founding of the People's Republic, Ni paulownia wood with greater enthusiasm into the cause of building socialism. In 1950, Ni paulownia wood Yunnan Tin Corporation, was appointed chief engineer in the mining, mineral processing, smelting technology in both work to accomplish something, especially in the development of gravity beneficiation equipment has made remarkable achievements. In 1958, he was wrongly classified as "rightists", who put him removed from YTC. He was the personal gains, insisted to stay in the YTC complete re-election have not yet done the work on the development of new equipment. 1974 retirement, left the old man, although the heart is still tied YTC, actively and conscientiously to the parties put forward their own ideas and proposals. In 1979, Yunnan Tin Company of Ni paulownia wood to be classified as right wing to give correct the wrong case. 1980 Ni paulownia wood is 80 years old, was invited to participate in Yunnan Tin Company's utilization of the meeting held in Ministry of Metallurgical Industry, the development of Yunnan Tin Company made a number of recommendations. May 20, 1984, Ni paulownia wood died of illness in Jinan.
Mineral processing equipment in China pioneer of modern gravity
Old history of mining, but the backward technology and equipment, mostly with homemade dressing, use only the mechanical shaker concentrator is imported from Britain. When Ni paulownia wood came here in 1941 as the election Yunnan Tin Co., Ltd. old factory manager at a time when World War II. Japanese troops occupied Hong Kong and Vietnam Hai Phong, the old processing plant Mianlin import?vibrating table?To continuously without loss supplement supply, production will not be seeing the situation. Ni paulownia wood is not satisfied, self-determined development. 1943 in the second half, a successful trial?table concentrator?cement surface, tested in production, the results are satisfactory; but still needed the cement imported from abroad, cement shaker can not promote. He did not despair and continue to develop new shaker. In the development, the Ni paulownia wood Huang adopted the recommendations of skilled workers, the use of lacquer waterproof characteristics, developed shaker lacquer surface. Through trial and modified in 1944, made a successful paint shaker. Shaker lacquer surface hardness, friction and wear are not breathable, immortal loss, separation of fine grade ore is good, technical indicators over imports shaker. Ni paulownia wood lacquer shaker written papers, the importance of the international mineral industry. Thus, instead of imported paint shaker shaker, and long-term production practice constantly improve and perfect. 40 years later, "YTC" brand paint shaker Brazilian exports in 1984 and the United Kingdom.
Old mine homemade dressing, employing bucket of water, workers, regardless of cold and heat, standing in pond operation, not only work hard, fine-grained cassiterite and low recoveries. Ni paulownia wood made with artesian water supply of curtain method. Just when the ineffective trial, reinvent the wheel. After repeated trials, in 1943 the successful development of artesian water supply of the "uniform sub-tank", the role of the use of slope water to achieve the enrichment of selected other purpose than the artificial brick Cao law advanced bucket of water, can improve efficiency and save 80% of workforce .
Old mine ore Shizhong Xi Shi disseminated fine grain size, tin with dense, fine-grained cassiterite ore recovery is one of the key production technologies. Ni paulownia wood With their solid theoretical knowledge and practical experience of long-term, break through the traditional theory of re-election, convection film dressing made of new ideas, and other engineering and technical personnel, workers together in the late 1950s developed a turn-bed, six sludge recycling shaking so fine cassiterite particles re-election of many new devices, so that fine particles in the YTC cassiterite mineral recovery technology has reached international advanced level at the time. His design, development and continuous improvement of the water analysis device, pulp enhanced gravity concentrator meter of the production technology management played an important role. His theory of gravity beneficiation flow membrane, have a profound impact in beneficiation industry, respected by the academic community, has become a prestigious dressing experts.
Tin industrial base of the "boss"
Ni paulownia wood knowledgeable, proficient not only theory and technology of mineral processing and mining, smelting, machinery, construction is also very good at it. In 1950, he was appointed chief engineer for the Yunnan Tin Corporation, after enthusiastically take on the burden of building a new technology YTC. To meet the national need for the construction of the tin, a wealth of development resources into the development of Yunnan Tin tin old plant produced the key. After argument, decided to build a frame length of 16 km two-lane cable transport ore, tin ore the old plant shipped to Datun concentrator for washing. Central Ministry of Heavy Industry Nonferrous Metals Industry Administration in the country for no one volunteered to design the case, presided over by the Ni paulownia wood design and construction of command. YTC's scientific and technical personnel were not designed cable experience, Ni paulownia wood, I have never seen such a big load cable. For the design of cable, he and Li Fengtong, Pi chapter and other mountains, site investigation. The end of 1951 the design is completed, start in January 1952, completed 1953 test. In the testing process, to resolve the issue out of the bucket, the total Ni rolled up bedding, living for a month to move mine a whole. He asked his wife to his meal, his focus on observation, measurement, thinking, calculation, and finally to obtain the necessary data to solve the problem out fighting. This mine was China's longest cableway, to 90 years is still running, for the construction of our cable accumulated experience to develop a pool of talent. Same period, he also presided over the design and built a modern day processing 1,500 tons of tin concentrator - Datun oxidized ore dressing plant and part of the renovation and expansion project for the restoration, development and training of Yunnan Tin production technology has made important contributions.
Mining front and never retired, "soldiers"
Ni Tong mining wood love, love the YTC, with a high degree of professionalism and responsibility. In 1958, he was wrongly classified as a "rightist", punished by dismissal pay cut and proposed to him transferred. Although he was in difficult circumstances, but the personal gains, still insist to stay in Yunnan Tin to complete the re-election have not yet finished work on the development of new equipment. Yunnan Tin Company to meet his demands, he fully energy into mineral research. 1958 to 1960, he completed "YTC Flip", "20-layer bed turning" and "On the hydrocyclone used in several problems in the field of study" and six papers, the technical equipment used in production actually described and summarized. In 1960, Ni paulownia wood, the "rightist" After take off the hat, was appointed chief engineer of the Yunnan Tin-center trial. He offered to bed turn-based processing 600 tons of sludge on plant-building program. In 1963, Ni paulownia wood chair with a chute (Flip) and shaking the joint, poor sorting Donganshan hematite experiments, to feed grade 34.5% concentrate grade 60.58%, 88.05% recovery indicators, than the Soviet Union's full flotation and magnetic separation processes all the indicators is slightly higher for the poor hematite Donganshan lay the foundation for re-election.
In 1974, Ni paulownia wood retirement, with his son to settle in Jinan, Shandong. Have left the tin man, heart still maintain the mine. In 1974, he wrote to the Yunnan Tin Corporation, pointed out that the four production problems and their solutions. In 1975, he proposed to the Ministry of Metallurgical Industry vibration red iron ore concentrator pilot program to address the problem of poor iron ore beneficiation. In 1976, he learned that old drought, Yunnan Tin Company for nine consecutive times to write, to propose solutions of water ways. May 15, 1978, he gave the Ministry of Metallurgy Office of Science and Technology letter comrades, once again made using a vibrating sorting hematite mineral processing machine, "take off the red ore beneficiation technology," he wrote: " I was nearly ten days, and suffering from coronary heart disease, but also hoping to force out a little before the end of life take this off for a great four modernizations made a modest contribution. "At the same time, he gave the company responsible comrades of the YTC proposed development of vibration concentrator problem, Yunnan Tin Company personnel were studied. He also raised the "stick-generation ball" to address the recommendations of crushed ore over by the company's attention and use. In 1980, he traveled regardless of the frail and elderly, were invited to participate in Yunnan Tin Company's utilization of the meeting held in Ministry of Metallurgical Industry, to the Yunnan Tin Corporation made many good suggestions.
Ni paulownia wood production and construction concern YTC, YTC is more concerned about the growth of technical personnel. Back in the 1950s, he worked tirelessly to learn not only their own, personal counseling and training the younger generation. Under his care, some people have been self-taught, grew from a junior high school senior engineer for the dressing. After retirement, he continued to write to inform their colleagues, themselves from the old society, seen and heard strong feelings, Chinese people have stood up in 1949, but industrial and agricultural production developed, only a half points, but not all station, pay close attention to colleagues Love limited to mining science and technology rapidly developed. He was a middle-aged engineers and technicians to the letter affectionately wrote: "I came in 1941, YTC, you feel old this great non-ferrous metal ore, is the motherland of a large treasure." "No one wanted a strong country. it must be powerful four modernizations. to achieving the four modernizations, we all bear a heavy responsibility and hard, I can not put this responsibility on the edge of death. "YTC's advice to his comrades technical problems, he eleven to be technical guidance through correspondence. In his last breath of life, also left behind a letter to an engineer of the Yunnan Tin Company has not yet finished writing the letter. He dedicated his life to the motherland, mining, expressed his utter devotion to the socialist motherland.
