Abstract

Spiral chute is an efficient equipment for gravity separation. A numerical simulation model concerning sorting flow pattern and particle trajectory of the spiral chute was built using Computational Fluid Dynamics (CFD) technology to study the effect of the diameter and pitch to diameter. Trajectory of the spiral chute was built using Computational Fluid Dynamics (CFD) technology to study the effect of the diameter and pitch to diameter ratio on the sorting performance. The trajectories of the mineral particles with different particle sizes and specific gravities were modeled. Results show that the small-diameter spiral chute with a constant pitch to diameter ratio for the 5µm fine-grained heavy minerals; the spiral chute with a diameter of 1200mm and a pitch to diameter ratio of 5µm was modeled. The results show that the small-diameter spiral chute with a constant pitch to diameter ratio for the 5µm fine-grained heavy minerals; the spiral chute with a diameter of 1200mm and a pitch to diameter ratio of 0.45 can obtain more obvious enrichment effect for the 50µm fine-grained heavy minerals; the spiral chute with a diameter of 1200mm and a pitch to diameter ratio of 0.6 has a better sorting performance for the 100µm fine-grained heavy minerals. This thesis research provides guidance for the selection of industrial spiral chutes and the development of new spiral chutes.
