回转窑连续运转,使其卸料管也经常处于高温工作状态。由于煅烧料在卸料管内不断地冲击,使其拐弯角内壁中心点处极易磨穿漏水。过去,往往因此迫使回转窑煅烧工序仃产抢修。一般每抢修、挖补一 Rotary kiln continuous operation, so that the discharge tube is often in high temperature working condition. As the calcined material in the discharge tube constantly impact, so that the corner of the wall at the center of the pole wear easily wear water leakage. In the past, it was often forced rotary kiln calcination process to stop production repair. Generally every repair, dig one
