pellet and benificiation process pellets of 13-19 mm size with 3.47 to 3.56 Kg per pellet green strength. After air drying followed by heat hardening at 250-300°C the pellets had an average compression strength of about 80 Kg per pellet. It was observed that due to sudden raise in temp. in the rotary kiln some of the pellets were crushed.
