MATERIALS HANDLING RESEARCH: HYDRAULIC TRANSPORTATION OF COARSE SOLIDS

A fully automated pilot plant was constructed to study the hydraulic transportation of solids. An equation for the energy requirements to transport coarse solids hydraulically proved applicable to this system. Optimum velocities were obtained for limestone, mine refuse, and bituminous coal. The experimental data, calculations, and graphs show the effect of velocity, specific gravity, and solids concentration on head loss and power requirements. Other data were obtained and evaluated to determine the effect of particle size on head loss. Results also are given for (1) tests using friction reducing polymers; (2) tests using 7 test sections of steel alloy pipe to determine their wear characteristics; (3) tests to determine spatial segregation of moving particles; and (4) tests to determine the effect of shape, size and specific gravity on particle velocity in a horizontal pipeline. The lock hopper feeder system was found practical for continuous hydraulic transportation of the material types and size ranges tested.
