摘　　要：探讨了膨润土焙烧活化改性的机理,找到了焙烧活化的最佳工艺参数,即焙烧温度为450℃,焙烧时间为2h。并用改性前后的膨润土进行了对比造球试验,试验结果表明球团的生球落下强度、抗压强度、爆裂温度均有所提高。Bentonite roasting modifying mechanism has been studied in this paper and optimal process conditions have been found. That is temperature 450℃ ,2 hour of response time, and the contrasting experiments have been done by using the bentonites that modified and unmodified. Results indicate that the incidence intensity of greenball,the compressive strengty and the bursting temperature are all improved.
