COAL MILL PERFORMANCE OPTIMISATION Continued. Coal is first crushed by coal crushers to a size of 20 to 25 mm and is then fed to coal bunkers. Coal feeders feed this crushed coal continuously to coal mill as per requirement. Coal gets ground by grinding elements in stages. Coal particles get recirculated around four times before achieving required fineness.
