Abstract

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.

Şeftali Çekirdeği ve Linyit Kömür Tozundan Yapilan Peletlerin Fiziko Mekanik Özellikleri

Abstract

Bu çalışmada, şeftali çekirdeği (SÇ) ile linyit kömür tozunun
(LKT) farklı karışım elde edilmiş ve 3 kW motor gücüne sahip (redüktör dönü
sayısı: 96 devir/dakika), işleme kapasitesi 50-60 kg/h olan, dairesel sıralı
delikli düz kalıp olan peletleme makinesinde peletlenmiştir. Pelet kalıbının
giriş delik çapı 11 mm, çıkış delik çapı 7 mm ve kalıp boyu 25 mm'dir. Peletler
%100 ŞÇ, % 90ŞÇ +%10 LKT, %75CP+%25 LKT, % 50ŞÇ +% 50LKT, % 25ŞÇ +%75 LKT, %10
ŞÇ +%90 LKT ve %100 LKT karışım oranlarında kuru halde peletlenmiştir. Pelet
parça yoğunlukları 647.03 ile 1059.15 kg/m3 arasında değişmiştir. En
düşük dayanıklılık direnci (%67.60) %100 LKT’da meydana gelmiştir. Şeftali
çekirdeğinin artmasıyla dayanılılık direnci artmıştır. En yüksek kırılma
direnci % 100 seftali çekirdeğinde (%99.57) meydana gelmiştir.
