烧结机漏风是烧结厂的棘手问题，由于漏风导致烧结矿产量降低、质量下降、反矿增多；设备磨损严重；能耗升高等。针对这一问题提出了新的密封结构——高负接触头尾密封装置、无铆接双板簧和新的传动方式——星轮传动的变齿距设计以及增设尾部液压阻尼装置。在现场实施后证明是行之有效的，烧结机总漏风率下降了27%。
Air leak is a intractable problem of sintering machine. Air leak may lead to depression of sinter output, lower quality, increment of waste ore, serious equipment attrition, as well as high energy consumption. A new air seal equipment, that is the high minus pressure contact airproof technology for wind box of the head and tail of sinter machine, without riveting twin sheet iron are proposed. The alternation of teeth space of spider drive are designed, hydraulic damper on tail spider are added. The practice had demonstrated that the total air leak of sinter machine are reduced 27%.
