Anotace	The flow behaviour of coarse-grained slurry depends on particle size, shape, density and concentration, and on the density and rheological properties of the carrier liquid. The present paper describes the results of an experimental investigation and flow visualisation of model coarse-grained slurries in a re-circulating pipe loop with smooth stainless steel pipes of inner diameter 36 mm. Glass balls and washed graded pebble gravel of mean diameter d₅₀ = 6 mm were used as models of coarse-grained material. The effect of slurry velocity and particle concentration on the slurry behaviour and pressure drop was evaluated. Particle distribution in the pipe cross-section and motion of particles along the pipe bottom, particle saltation and particle conveying in the carrier liquid were observed in a transparent pipe viewing section. Velocity profiles of the carrier liquid and conveyed particles were determined.
