我国有丰富的石棉资源。但是,石棉的生产远不能满足莲勃发展的国民经济的需要。目前,石棉选矿工艺技术是石棉原料工业生产既重要又十分薄弱的环节。所以,石棉选矿工艺技术的改进和发展是增加生产能力,提高产品质量,改善劳动条件的关键。为了加速石棉生产的发展,国家建材总局下达了“石棉风选工艺技术研究及设备的研制”的科研项目,振动空气净化机(又称比重分选机)的研制就是该项目的组成部分。
Our country is rich in asbestos resources. However, the production of asbestos far can not meet the needs of the booming national economy. At present, asbestos beneficiation process technology is an important and very weak link in the industrial production of asbestos raw materials. Therefore, the improvement and development of asbestos dressing technology is the key to increase production capacity, improve product quality and improve working conditions. In order to speed up the development of asbestos production, the State Administration of Building Materials issued a research project “Research and Equipment for Asbestos Wind Selective Technology” and the development of vibrating air purifier (also called gravity separator) is an integral part of this project.
