Distribution Feeder Principles. Distribution in the Power Hopper Design Principles Chemical Engineering Page 1,Feeders can also be a source of hopper flow problems if the incorrect devices are used or if they are improperly designed. This is especially true for hoppers with slotted outlets, where feeders should be designed to draw uniformly along the entire cross-section of the outlet in order for mass flow to occur. However, even hoppers with round outlets can have uneven flow if a proper interface is not utilized.
