Wood pellets transport with vibrating conveyor: experimental for DEM simulations analysis

Abstract This work presents a comprehensive overview of the mechanical-physical parameters of the transport material affecting the vibratory transport. For this purpose, spruce pellets of different lengths, oak rods and spruce crush were tested. The determined parameters were particle size distribut...
