| Abstract | ||
| The benefits of agricultural residues include several opportunities for processing them into economically products. Therefore, this study aimed to adapt the cutter-mixer machine “CMM” to manufacture green-garden residues (GGR) as the form of soil green-fertilizer (SGF). This process is the primary step for converting the GGR into fertilizer by constructing the cut-mixer machine. The cut-mixer machine (CMM) is tested and evaluated under three levels of mixing time (5.0, 7.5 and 10 mints) and three levels of cut-mixer shaft speeds (60, 90 and 120 rpm). The results concluded that the CMM can produce the green-fertilizer (SGF) at the appropriate levels of the studied variables: 7.5 min mixing time and the cut-mixer shaft speeds of 90 rpm. Comparing the calculated values of tracers (moisture and ash content) for the mix components (St) with the existing materials in the mixture, it was found that the moisture content decreased by 0.016% and the ash content decreased by 0.345%. The coefficient of variation for tracers (MC) and ash percentages were zero values and 1.37%, respectively. The mixing efficiency was about 99.06%, and the energy requirement was 7.77 kWh/ton. | ||
