Abstract
This paper improves the existing pressure pipe rheological and resistance characteristic test system and optimizes the pressure and flow data acquisition method. Taking coal slime as an example, it conducts an experimental study on dense paste's rheological characteristics. It ensures the coal slime's rheological model transported in different pipe diameter of which the volume concentration is 57.06%～45.44%and analyses the rheological characteristic trend changing with diameter and volume concentration. The experiment proves that the new system is practicable and easy-operated and reliable. Also the original experimental data and processed result are in accordance with theoretical regulation.
