In order to provide a technical basis for preventing the blockage of heterogeneous slurry pipelines, the unsteady characteristics of slurry transport were studied. Our experiments were carried out using a test pipeline of about 130m long and 50mm in diameter. The flow rate, the solid concentration and the pressures were measured in the pipeline, in terms of responses to a stepwise charge of solid particles. It became clear how behavior of slurry changed in the pipeline if it changed with the feed rate of solid particles and how the phenomenon of the pipe blockage happened. Various information and data were obtained from these experiments, which will be useful in planning and in operating heterogeneous slurry pipelines.
