China is rich in mineral resources, so it has great growth room in the development of the beneficiation equipment industry. With a large number of development and utilization of mineral resources, mining ore taste gradually reduces. The dressing products quality requirements of smelting and other subsequent processing are also increasing. At the same time, our environmental protection consciousness strengthens day by day.
At present, our country makes a lot of research work in the mineral beneficiation equipment, and has achieved certain achievement. The main classification of domestic beneficiation equipment products are dry magnetic separator, wet magnetic separator magnetic separator, iron remover electric separation machine, flotation machine, high frequency screen, spiral classifier, hydrocyclone and so on.
The reality has put forward higher requirements on mineral processing equipment. They encourages dressing equipment continuously to develop to the direction of bigger, better, high efficient and energy saving. Large scale and high efficiency beneficiation equipment is coupled with the effective automation control technology. This will obtain good economic benefit and social benefit.
Mineral beneficiation machinery and equipment with large scale can not only reduce the maintenance cost and production cost, but also can reduce occupation area and power consumption. Then, it can reduce the investment in infrastructure, and improve the mechanical processing ability. It is also easy to realize automatic operation. With the development of large-scale beneficiation machinery and equipment, production efficiency of large refineries in China will be further improved, and play a tremendous role in promoting national economic construction.
So the large-scale is so important for our future development. It is one of the current development emphases about the beneficiation equipment. Automatic control technology is also our current development emphases. We should make full use of the processing technology of new materials, new technology and science. Strengthen the development of large-scale machinery and equipment processing. Pay attention to the electromechanical integration and application of automatic control technology. Promote the development of high efficiency and energy saving of beneficiation equipment.
In a word, with the national energy saving and emission reduction, we should actively introduce advanced technology, and make t efforts to develop high-tech level beneficiation equipment. We are working hard to promote the beneficiation machinery and equipment toward the high efficient and large-scale development direction.
Current Development Of Vibrating Screen Abroad
Host: Are you all familiar with the vibrating screen? Do you all understand the current development situation of vibrating screen? Today, we are honored to invite the expert from the Shanghai ZENITH—Mr. Wang. Welcome him to introduce the vibrating screen.
Mr. Wang: Good morning, everyone. I’m happy to participate in the interview. Hope today’s introduction will help you.
Host: Mr. Wang, someone may be familiar with vibrating screen. But he or she may be strange with the development of it. Can you first introduce it for us?
Mr. Wang: No problem. In sixteenth century, Britain first began to study the screening machinery, and created the world's first fixed sieve for coal industry. In eighteenth century, during the European industrial revolution, screening machines has the rapid development. At the beginning of the nineteenth century, some of the coal mining enterprises began to use cylindrical sieve, shaking screen. Some places appeared some simple vibration screening machinery.
Host: In recent years, social demand for energy and mineral increase sharply, so that vibrating screen in abroad is rapid to develop. How about the current development of vibrating screen in abroad?
Mr. Wang: At present, the well-known foreign enterprises make use of computer aided design technology, and advanced manufacturing technology. They not only produce the machine with a very wide applicability and a variety of specifications, but also produce the high reliability, good performance, large and oversize vibration sieve. The vibration device has the world's leading technology. They represent the current trend of the industry development.
Host: At present, what are the breakthroughs about the vibrating screen in the world?
Mr. Wang: At present, the foreign research mainly has the following several kinds of vibration sieve. Germany HayerSoecker company manufactures the world's largest vibration sieve (R1E4x 10.5m). The vibrating screen’s work area is 42 square meters. The weight is 115 tons. The largest processing capacity is 10000t / h, and the total power is 264kW. The original Swedish Svedala group created the world's largest double linear vibrating screen. The equipment’s maximum processing capacity is 5000t / h. American company manufactures the high frequency vibrating fine screen. The grading capacity of Large vibration screen produced by Japanese Kobe Steel is 500t / h.
Host: OK. Thanks Mr. Wang’s detailed introduction about the current development of vibrating screen in abroad.
Mr. Wang: You are welcome.
