20 10 Anshan heavy mining machinery co., ltd 4392 banana-shaped linear vibrating screen won the 2009 China machinery industry science and technology award.
20 1 1 released by Anshan Top 100 Industrial Enterprises, Anshan Heavy Mining Machinery Co., Ltd., as a leading vibrating screen enterprise in China, was selected as the 56th among the Top 100 Industrial Enterprises in Anshan.
20 1 1 In the first half of the year, the secondary vibration screening method for the screen surface of heavy mining machinery in Anshan, as well as the large vibrating screen, vibrating screen with motor and vibrating screen with gradually changing vibration frequency, won the national invention patent again. Over the years, Anshan Heavy Mining Machinery Co., Ltd. has always been aiming at "quality first, customer first" and passed the ISO900 1:2000: 2000 international quality standard certification.
Saddle weight patent: 4.3m×9.2m large banana-shaped 100 line vibrating screen. The screening area of this project is 39.56m (4.3m× 9.2m) aromatic vibrating screen. It is characterized by a screen surface width of 4.3m, a length of 9.2m, a height of 5m and a weight of 40t, and the screening capacity can reach 2500t per hour. It belongs to a new type of machinery in the field of high-tech transformation of traditional industries and technologies. Banana vibrating screen is a key screening equipment widely used in large coal preparation plants and mineral processing plants such as coal mines. Because the vibrating screen vibrates back and forth when working, the larger the screen surface, the easier it is to deform, which leads to the damage of the screen body and the shortened service life. Large vibrating screen technology has always been a worldwide problem. Previously, foreign manufacturers such as Australia and Germany monopolized the global banana big screen market. Australia developed a large banana screen with a screen surface of 38.4m(4.2m×9. 15m), while China only developed a large cold ore screen with a screen surface of 27m(3m×9m). Therefore, China needs hundreds of large banana screens every year, and has always relied on imports.
Aiming at the difficulty of low production capacity and screening efficiency of traditional vibrating screen, a new banana screen with wide screen surface was built by adopting the patented technology of banana-shaped multi-section screen surface linear vibrating screen and advanced multi-section screen surface structure, and the screening area reached 39.56 m, which significantly improved the production capacity and screening efficiency. Aiming at the difficulty that the wider the screen surface, the shorter the service life, the modern design methods such as finite element analysis and optimization design are innovatively used to scientifically calculate the main components. Breakthrough the scientific material selection and safe and reliable key technology of 39.56m banana screen, and improve the service life.
Compared with foreign similar products and international scientific and technological literature retrieval, it is proved that the screening area of this project is 39.56m, ranking first in the world. The technical performance indexes such as amplitude, vibration intensity and production capacity exceed those of advanced foreign manufacturers; The vibration frequency index is quite close to that at home and abroad.
In February 2008, it passed the technical appraisal. It is considered that the achievements of this project are innovative and fill the gaps at home and abroad. The overall technology has reached the international advanced level, and some indicators have reached the international leading level.
The product of this project has the advantages that a large banana screen can replace the parallel combination of several small and medium-sized vibrating screens, saving floor space and engineering investment. It has been widely used in coal, mining, metallurgy and other fields, which has promoted the industrial structure adjustment of equipment manufacturing industry and the economic development of equipment users.
