Introduction of high efficient “Flip-Flow Screens” for screening of very high moisture materials more specifically “Coal“ has changed the philosophy of conventional screening methods in power sector. In India coal is most sought after fuel for Thermal Power units and most of the time either coal will be imported or mined from open cast mines and stored in open areas leading to high moisture absorption. The high moisture levels in the coal will be crushed and screened before it goes for boiler firing the challenge lies in screening “high moisture coal “ conventional screening methods used will not able to productive and meet the demands of the plant. Introduction of Flip Flow Screen has ability to screen coal with moisture of 40% and efficient enough to the levels of 90% screening
