Knowledge of the rheological behavior of saturated particulate networks is crucial for every process in which a particulate network is built-up, dewatered, or transported, as in a decanter centrifuge. However, difficulties arise as to how to characterize the material properties. Thus far, no standardized method or measurement device has prevailed. In this work, the requirements for a useful device are discussed, followed by the design of a modified shear cell for a Schulze ring shear tester RST-01.pc and its measurement procedure. Shear experiments under normal load with different sediments consisting of inorganic and organic particles whose material properties strongly affect the rheological behavior were performed. The results demonstrate the potential of the modified shear cell. Furthermore, current challenges in characterization are discussed. The characterization possibilities of the developed shear cell are a further step toward understanding the rheological behavior of liquid-saturated particulate networks.

改进的剪切池用于表征压缩状态下颗粒网络的流变行为

就像在can析器离心机中一样,对于饱和的颗粒网络的流变行为的了解对于建立,脱水或运输颗粒网络的每个过程都至关重要。然而,关于如何表征材料特性出现了困难。迄今为止,还没有一种标准化的方法或测量设备能够盛行。在这项工作中,将讨论对有用设备的要求,然后讨论Schulze环形剪切测试仪RST-01.pc的改进剪切单元的设计及其测量过程。进行了在正常载荷下使用由无机和有机颗粒组成的不同沉积物的剪切实验,这些沉积物的材料性质对流变行为有很大影响。结果证明了改进的剪切池的潜力。此外,讨论了表征方面的当前挑战。
