The flow of solid‐liquid mixtures in a novel tube configuration was investigated and the results were compared to those obtained with a single‐helical tube configuration. Residence time distribution (RTD) of polystyrene and acrylic particles as affected by different processing parameters was determined. The studied parameters included flow rate, carrier fluid consistency, particle concentration, and curvature ratio of the helical tube. Curvature ratio and flow rate were found to be the most important factors affecting the RTD of particles. Interactions between particles appeared to be important, as the RTD of acrylic particles decreased significantly whereas that of polystyrene particles increased slightly upon mixing the two types of particles.
