改善矿山企业选矿厂劳动条件的重要措施之一,是厂房里的防尘和除尘工作,这个问题已引起科研设计及工厂试验等单位的重视。近年来,他们已研制了各种输送机和装料站的密封罩等许多除尘装置。根据苏联试验设计部门专家们研究结果,拟定了带宽为0.5～2米的带式输送机吸尘密封 One of the important measures to improve working conditions of concentrator in mining enterprises is to prevent dust and dust in the workshop. This issue has caused the attention of research institutes and factories. In recent years, they have developed a number of dedusting devices, such as sealed enclosures for various conveyors and loading stations. According to the Soviet Union’s experimental design department experts, the study developed a bandwidth of 0.5 to 2 meters belt conveyor vacuum seal
