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/m3 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
