Abstract (2. Language): 
In this study, the tea factory wastes were pelleted for the utilization as a solid fuel. The moisture content and geometric mean diameter of ground tea wastes were 12.68% and 0.62 mm, respectively. A laboratory-scale pelleting machine with an electrical motor powers of 3 kW was used for pelleting of raw material. Physical properties related to pellet quality such as bulk density, particle density, durability, compressive resistance and moisture sorption of pellets were determined. Also, the average capacity of the pelleting machine was measured. The pellets were stored under ambient conditions of 24 °C temperature and 55% relative humidity during 7 days before testing. At the end of study, the average diameter, length and mass of the pellets were 6.1 mm, 23.5 mm and 0.8 g, respectively. The average bulk density, particle density, durability and compressive resistance of pellets were found as 601 kg m-3, 1158 kg m-3, 81% and 476 N, respectively. Moisture content of pellets were decreased at low temperature and relative humidity conditions. As a result, physical tests showed that produced pellets were strong. The average pellet production capacity of the pelleting machine was found to be 46 kg h-1.

Abstract (Original Language): 
Çalışmada, çay fabrikası artıkları katı yakıt olarak kullanılmak üzere peletlenmiştir. Öğütülmüş çay atıkları, %12.68 nem içeriğinde ve 0.62 mm geometrik ortalama çapında ve laboratuvar ölçekli 3 kW güçlü pelet makinesinde çevre şartlarında peletlenmiştir. Peletlerin kalitesi ile ilgili fiziksel özellikleri olarak hacim yoğunluğu, parça yoğunluğu, mekanik dayanıklılık direnci, darbe dayanım direnci, basınç direnci ve nem alma durumu belirlenmiştir. Ayrıca çalışmada, pelet makinesinin kapasitesi ölçülmüştür. Fiziksel testler öncesinde peletler 7 gün süre ile 24 C sıcaklık ve %55 bağıl nem şartlarında bekletilmiştir. Çalışma sonunda, ortalama 6.1 mm çapında, 23.5 mm uzunluğunda ve kütlesi 0.8 g peletler elde edilmiştir. Çay peletlerinin hacim ve parça yoğunluğu 601 kg m-3 ve 1158 kg m-3, mekanik dayanıklılık direnci %81 ve basınç direnci 476 N bulunmuştur. Peletlerin nem alma direnci ortam sıcaklığı ve nemine bağlı olarak değişmiştir. Peletler düşük sıcaklık ve bağıl nem koşullarında nem kaybetmiştir. Çay peletlerinin fiziksel testler sonucu sağlam yapıda olduğu görülmüştür. Pelet makinesinin kapasitesi 46 kg h-1 olarak bulunmuştur.
