摘要
Abstract
Heavy medium cyclones have been widely used in the field of coal preparation. The fine particles of Si and SiC in different densities are likely aggregated,resulting in difficulties in chemical separation. This paper presented an experiment in the separation of Si particles from SiC particle using a heavy medium mini-cyclone. Simulation of the tangential velocity in the heavy-media mini-cyclone was conducted in order to study the flow field characteristics,and the influences of density and viscosity on the tangential velocity in the cyclone. The simulation software was CFD Fluent. Results showed that the influences of the viscosity were greater than the density. The tangential velocity increased when the density of the heavy medium increased. The tangential velocity decreased with the increase in the viscosity of the heavy medium. The swirling decayed more quickly in smaller cyclones.关键词
