STUDY ON SOME DIFFERENT OPERATING PARAMETERS AFFECTING THE PERFORMANCE OF COMPOST TURNING MACHINES

Experiments were carried out to evaluate the performance of two compost turning machines for producing organic fertilizer by recycling agricultural wastes. To fulfill objective this research work, some operating parameters affecting taken into consideration: Three different types field crop residues  rice straw, cotton stalks and corn stalks, four machine forward speeds 1.0, 1.2, 1.4 1.6 km/h, drum 150, 200, 250, 300 rpm times 1, 2, 3 4 times/month considered. Evaluation was taking consideration density, period maturity, productivity, energy requirements final quality. The obtained data revealed that quality in optimum range with use self-propelled under conditions km/h speed, 250 speed three times/month. Results also required least maturity 8 weeks, followed rice straw 12 weeks while longest of16 weeks.
