Separation of coal fines with dry-type pneumatic separator

The most common method of treating fine slime is pressure filtration without separation,so the slime products with high moisture need further treatment.To reduce moisture of fine slime,improve its calorific value,lighten the load of coal slurry preparation system,provide the dry-type pneumatic separation method.Introduce its principles and feasibility theoretically.Analyse the basic processes,find that this method can avoid part of fine slime into primary cleaning system.Setting the separating room as ideal condition,carry out force analysis of single coal powder granule,calculate the main separating parameters in separation room.Primary benefits estimation indicate that,dry-type pneumatic separator for coal fines worth further promotion due to its considerable social and economic benefits.
