Removal of fusain with a small-diameter H.M. cyclone operating with ultrafine medium particles
- Coal Preparation Research Inst., Tangshan (China)
As evidenced by study of physio-chemical property and liberation characteristics of the macerals of Shenfu young coal, the vitrain differs slightly with fusain in density, with the density of the former being about 0.1g/l higher. After being crushed to {minus}0.5mm, the individual maceral can be liberated, and the fusainite content in the {minus}0.043mm size fraction is noticeably higher than that in the 0.5--0.043mm size fraction. Based on the theory and practical cleaning result obtained through using a small-diameter cyclone for efficient cleaning of fine coal according to density, tests on the removal of fusain from 0.5--0.043mm size coal were conducted with a small-size cyclone operating with ultrafine medium. The test proved to be successful, with a fusain removal rate of up to 50%.
