TESTING OF THE HYDROFLOAT SEPARATOR FOR COAL CLEANING

teeter bed. In coal applications, the selective attachment of air bubbles makes it possible to recover very coarse, low-ash particles that would otherwise report to the reject stream of traditional hindered-bed separators.

Processing of coal fines using air fluidization in an air

10.04.2016· The progress of segregation by air fluidization of coal particles over an inclined deck was studied by Chalavadi et al. (2015). The authors identified the separation pattern with reference to a high ash coal in this work. The applicability of an air table for fine coal cleaning was established by Chalavadi et al., 2016. The authors developed

Dry separation on coal–silica mixture using rotary

01.03.2015· The clean coal ash content reduces to 24.66% when the rotating speed is increased to 4000 rpm. It shows that the higher charger rotating speed could increase the particle charging efficiency and then improve the electrostatic separation efficiency. As the charger rotating speed continues rising to 5000 rpm, the clean coal ash content increases to 31.16%. It might result from the too severe
