| 摘 要： | 由于充填料浆属于非牛顿体,其粘度值受多种因素影响而变化,不可能像普通牛顿体那样采用管流法、落体法、圆盘法、振动法等进行简单量测.根据充填料浆特性,以新桥硫铁矿尾矿浆(质量浓度70%)为研究对象,进行了充填料浆粘度测定方法的探讨.结果表明,待测充填料浆充分搅拌后2 min内利用旋转粘度计测得的粘度值变化幅度小于±15%,...

| Abstract: | Tailings backfilling slurry is one of non-Newtonian fluids,of which viscosity is affected by many factors,can not be measured easily with tube-flowing method,ball-dropping method,plate-rotating,and vibration method.Taking the tailings slurry with a mass concentration of 70% from Xinqiao Pyrite Mine as the object of study,according to the characteristics of backfilling slurry,the method to measure the viscosity of backfilling slurry was discussed.A rotary viscometer was used to measure the viscosity of the t... |
