从1959年开始,我厂的赤泥洗條系统采用了直径12米的三层沉降槽。最初,由于对赤泥膨胀性能没有掌握,经常出现溢流跑浑和垮槽事故,主要技术经济指标很差,因此有人认为,烧结法赤泥洗條系统不宜采用三层沉降槽。但从1961年以后,我们经过试验研 Since 1959, the red mud washing system of our factory has adopted the three-layer settling tank with a diameter of 12 meters. Initially, due to the lack of mastery of the red mud swelling performance, often overflow run muddy and collapse trough accidents, the main technical and economic indicators are poor, so some people think that sintered red mud washing system should not be used three sedimentation tank. But after 1961, we passed the experimental research
