Abstract
A novel dry type high gradient magnetic separation (HGMS) device comprising a fluidizing bed is studied for the purpose of the pulverized coal beneficiation. The separation performance of the device is examined related to powder size, gas velocity, amount of feed, processing time, wire size and repeated process. Chinese Coal in the size range of 44 and 297 μm in diameter with high magnetic susceptibility compared with other coals can be cleaned by magnetic effect. About 33% ash reduction at 86% coal recovery is observed at 1.5 minutes processing (3 passes).
