Cold crushing strength (CCS) of iron ore pellets varies widely from as low as 80 Kgf / pellets to as high as 350 Kgf /pellets depending upon the input material quality and the process variables. The most preferred range of CCS of iron ore pellets is 180-240 Kg f / pellets which were normally found in the proportion of 35-40% at the plant.
