OPTIMIZATION OF ORGANIC FERTILIZER DISTRIBUTION USING EDEM SIMULATION ANALYSIS

This study investigates the distribution performance of solid organic fertilizers using vertical helical rotor equipment, focusing on the optimization of spreading uniformity. EDEM simulations were employed to analyse the particle flow and distribution patterns under varying rotor speeds (360, 440, and 540 rpm) and inclination angles (75°, 80°, and 85°). The results indicate that the most uniform distribution is achieved at 540 rpm with a 75° rotor inclination. The study was extended to a configuration with four rotors, simulating field-like conditions. Although a good lateral and longitudinal spread was observed, material concentration along the machine’s central axis suggests a second pass is needed for complete field coverage. These findings contribute to the design optimization of fertilizer spreading equipment to improve efficiency and application precision.
