Abstract
A method of discharging particulate material from a hopper which minimizes vibration and impact loading is disclosed. The method provides a centrally located discharge column having a series of discharge openings extending vertically of an annular mass of particulate material in the hopper. The particulate material is discharged from a generally conically shaped, downwardly and inwardly directed, top portion of said mass of particulate material, progressively downwardly, through a choked flow discharge path provided by the interior of the discharge column.
