Development of dry coal gravity separation techniques

Dry separation method was used at the beginning of 20 th century to separate coal separation process First industrial applications of dry separation took place in the middle of 1930s At that time air separator Frazer Yankey based on aero suspension was used in in Pittsburgh and Lundale West Wirginia coal preparation plants Later some more constructions like RAW air jig air table V

coal gravity separation how it works

Coal washing involves grinding the coal into smaller pieces and passing it through a process called gravity separation One technique involves feeding the coal into barrels containing a fluid that has a density which causes the coal to float while unwanted material sinks and is removed from the fuel mix
