Pellet - an overview ScienceDirect Topics

In accordance with ISO 4700, the cold crushing strength (CCS) of pellets is the arithmetic mean of measurements of a test sample of at least 60 pellets of − 12.5 + 10 mm particle size. From practical experience, a crushing strength of 200 kg, preferably 250 kg, is desirable for pellets to be used in large BFs. View chapter Purchase book

Study and Implementation of Quality Improvement

2015-11-13  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.
