Advantages of Coal Hammer Mill. Efficient Grinding: We use hammer mills to efficiently grind coal into tiny particles, which create a lot of surface area for combustion or other uses. It enables the effective and comprehensive pulverization of coal, which can improve coal-fired power plant combustion efficiency or assist other coal-useGrinding of the samples has been conducted in following two devices. One was hammer mill where breakage is predominantly by impact of the hammers on the coal. The hammer mill used in this experiment is a laboratory hammer mill. A mill has been designed which is a horizontal plate crusher type. In which particle breakage take place by shear.Effect of Grinding Behavior on Liberation of Coal Macerals J
