The flow of spherical particles in a conical hopper with the cone angle 45° is studied using DEM. Density and size of particles are 2500 kg/m3 and 9 mm, respectively. Diameter of the conical hopper is 20 cm and diameter of the exit orifice is 8 cm. A wide, flat wide plate is located 14 cm below the exit orifice on which a pile of discharged particles is formed. The DEM simulation consists of two stages: the first stage is filling of the conical hopper in which the exit gate is closed, the second stage is discharging the conical hopper in which the exit gate is removed and particles are allowed to exit the hopper under the gravity.
