摘要：
Spiral separator is a gravity concentration device. It was invented by Humphreys in 1941.It is firstly designed and developed based on experience and through many testing of prototypes and modifications. The main objective of the present study is simulation of the particulate-flow of more realistic solids concentration (15% solids by weight) in spiral separator. The study is based on Eulerian approach and RNG K-epsilon turbulence modeling. The results focus on particulate-flow characteristics such as velocity, and distribution and concentration of particulates on the spiral trough. The predicted results are compared with the experimental in case LD9 coal spiral. Comparisons between numerical and measured data show good agreement.
