Discharge Hopper Feed


Hopper Design Principles - stone Engineering | Page 1

Screw feeders are primarily used to control the discharge of powders from hoppers with slotted outlets A screw is comprised of a series of flights wound around one or more shafts A screw that has a constant pitch and diameter (and a constant shaft diameter) will give rise to the formation of a flow channel at the back of the hopper over the first flight of the screw
