Development of a DEM-Optimized Inclined Screw Fertilizer Distributor for Improving Discharge Stability and Metering Accuracy
Discharge uniformity and metering accuracy are essential for precision fertilization. An inclined screw fertilizer metering device with a spherical buffering outlet was designed and optimized using the discrete element method (DEM) and bench experiments. A particle-flow model was established using EDEM (DEM simulation...
