  • Prediction of Washability as a Function of Breakage ACARP

    The washability and recovery of coal is governed by two processes: breakage and liberation of stone from coal. The efficiency of liberation is coal type and particle size dependent. Particle size distribution is a function of the material properties of the coal and the breakage energy imparted to the coal as it is mined, handled and processed.
