Analysis on feasible way of the separation of coarse coal slime in coal preparation plant
LI Yu-yun
Abstract：Because that the separation of coarse slime was the emphasis and difficult points in the management of coal preparation plant, the feasible way of the separation of coarse slime in coal preparation plant was analyzed.The research shows, Spiral separator and interference bed are the feasible methods for separation of coarse slime in coal preparation plant, spiral separator is suitable for high density separation of coarse slime, low density separation is suitable for the use of interference bed separator, but the sorting accuracy of conventional interference bed is generally low, and it is suitable for washability or optional medium coarse slime.Application of interference bed with internal structures is one of the most important research direction washability in the future of the separation of coarse slime.
