Physico-Mechanical Properties of Pellets Made of Peach Pit and Lignite Coal Dust

In this study, peach pit (pp) with lignite coal dust-coal powder (cp) at specific ratios were pelletized by a pelletizing machine having flat die and roller with a capacity of 50-60 kg/h. the pellet die had an inlet hole diameter of 11 mm, an outlet hole diameter of 7 mm and a die height of 25 mm. the pellets mixtures was prepared as 100% cp, 90%cp+10%pp, 75%cp+25%pp, 50%cp +50%pp, 25%cp+75%pp, 10%cp+90%pp, and 100%pp as dry weight basis. the results showed that pellet particle density varied from 647.3 to 1059.15 kg/m^3 and increased with increase in the cp in the mixtures. durability resistance of the pellets ranged from 67.70 to 92.72%. the least durability resistant pellet (67.60%) was the one having the proportion of cp of 100% in the mixture. durability resistant increased with increase in pp in the mixture. the least shatter resistant pellet was the one having cp of 100% in the mixture. the highest shatter resistant pellet was the one having the mixture of 100% of pp.
