Abstract

Compost is considered an important source for agricultural fertilization, because it contains a high level of nutrients and organic matter. The compost is produced from different agricultural wastes and some additives like water and animal poultry residues. In this study, experiments were conducted to optimize some engineering and operating parameters affecting the performance of disk pelleting machine. The parameters under this study were four different roller rotating speeds of 175, 225, 275 and 325 rpm; fourdifferent die profiles of  Die-A (18.8 mm land length with 13.5 mm entry diameter), Die-B (20.3 mm land length with 13.5 mm entry diameter), Die-C (18.8 mm land length with 14.2 mm entry diameter) and Die-D (20.3 mm land length with 14.2 mm entry diameter); four different compost raw martial moisture contents of(15, 20, 25 and30%) wb.The obtained results revealed that the pelleting machine has a high efficiency and maximum pellets quality under conditions of 20% compost raw material moisture content, 275rpm rollers speed and die profile (C) of (18.8 mm land length with 14.2 mm entry diameter). The optimum results were 287.79 kg/h pelleter productivity, 19.81 kW.h/Mg energy requirements, 93.68% pellets durability and 108.31 L.E/Mg cost per mass unit.
