An insert system for changing the pattern of material flow in a bulk storage hopper during the discharge process, from a form where a channel flow develops within a mass of smile material into a form where the entire stored contents are caused to flow. This change is affected by the provision of insert members supported within the hopper, which modify the stress pattern in the flowing contents to allow the bulk material to deform more readily and for slip to take place on all contact surfaces between the material and the hopper walls.
