The behavior of slurries and suspensions made by mixing solid particles and liquids is very important for various industrial applications. The latest accidental failure events at tailings facilities (Kolontár, Baia Mare) have focused public interest into this field. Nowadays, environmental practice is turning to use dry deposition techniques or at least as high concentration slurries or pastes as possible, to avoid large spills in case of an accidental failure of an embankment. High concentration slurries are becoming widely accepted in many environmentally related operations such as underground backfilling or simple tailings deposition. However, the hydraulic transport of pastes or high density slurries requires higher energy input via pumps, and, in addition, the energy requirement or pressure loss calculation methods are also different because the rheology of pastes differs from that of dilute slurries. At the University of Miskolc, Institute of Raw Materials Preparation and Environmental Processing, Miskolc, Hungary, this topic has been studied for many decades. The fine suspension – coarse mixture flow model was introduced, and it has been determined that the flow behavior of fine suspensions made of solid particles smaller than a limit particle size can be measured and interpreted in almost the same way as for single phase clear liquids. Based on these measured rheological parameters of fine suspensions, the frictional energy loss can be calculated. The aim of this paper is to give a summary and data base about the rheological behavior of different industrial materials based on pilot scale hydraulic loop measurements. An Anton-Paar rotational viscometer and a tube viscometer with three measuring pipe sections, – developed by our institute – were used for testing. The results of measurements of various granular materials, such as sands, fly ashes, perlite, tailings and red mud are presented in connection with environmental applications. Based on these results, empirical relationships are presented, where the parameters are determined by simple function fitting into the data of measurements carried out at discrete concentration values. The rheology of fine suspensions of any concentration up to the measured maximum can be calculated by these relationships.

通过混合固体颗粒和液体制成的浆料和悬浮液的性能对于各种工业应用而言非常重要。尾矿厂（Kolontár，Baia Mare）的最新意外故障事件已将公众的关注集中在该领域。如今，环境实践正在转向使用干式沉积技术或至少使用尽可能高浓度的浆料或糊剂，以避免在路堤意外倒塌的情况下发生大量泄漏。高浓度泥浆已在许多与环境有关的操作中被广泛接受，例如地下回填或简单的尾矿沉积。但是，浆液或高密度浆液的水力输送需要通过泵输入更多的能量，此外，能量需求或压力损失的计算方法也有所不同，因为糊的流变性与稀浆的流变性不同。在匈牙利米什科尔茨的米什科尔茨大学原料制备和环境加工研究所，这个主题已经研究了数十年。引入了细悬浮液-粗混合物流动模型，并确定可以用与单相透明液体几乎相同的方式测量和解释由小于极限粒径的固体颗粒制成的细悬浮液的流动行为。基于这些测得的细悬浮液的流变参数，可以计算出摩擦能损失。本文的目的是基于中试规模的液压回路测量结果，提供有关不同工业材料流变行为的摘要和数据库。由我们研究所开发的Anton-Paar旋转粘度计和具有三个测量管段的管式粘度计用于测试。结合环境应用介绍了各种颗粒材料的测量结果，例如沙子，飞灰，珍珠岩，尾矿和赤泥。基于这些结果，提出了经验关系，其中通过简单的函数拟合将参数确定为在离散浓度值下执行的测量数据。可以通过这些关系来计算任何浓度的悬浮液的流变性，直至测量的最大值。由我们研究所开发的Anton-Paar旋转粘度计和具有三个测量管段的管式粘度计用于测试。结合环境应用介绍了各种颗粒材料的测量结果，例如沙子，飞灰，珍珠岩，尾矿和赤泥。基于这些结果，提出了经验关系，其中通过简单的函数拟合将参数确定为在离散浓度值下执行的测量数据。可以通过这些关系来计算任何浓度的悬浮液的流变性，直至测量的最大值。由我们研究所开发的Anton-Paar旋转粘度计和具有三个测量管段的管式粘度计用于测试。结合环境应用介绍了各种颗粒材料的测量结果，例如沙子，飞灰，珍珠岩，尾矿和赤泥。基于这些结果，提出了经验关系，其中通过简单函数拟合将参数确定为在离散浓度值下执行的测量数据。可以通过这些关系来计算任何浓度的悬浮液的流变性，直至测量的最大值。飞灰，珍珠岩，尾矿和赤泥与环境应用有关。基于这些结果，提出了经验关系，其中通过简单的函数拟合将参数确定为在离散浓度值下执行的测量数据。可以通过这些关系来计算任何浓度的悬浮液的流变性，直至测量的最大值。飞灰，珍珠岩，尾矿和赤泥与环境应用有关。基于这些结果，提出了经验关系，其中通过简单函数拟合将参数确定为在离散浓度值下执行的测量数据。可以通过这些关系来计算任何浓度的悬浮液的流变性，直至测量的最大值。
