A screw conveyor in a wheat flour mill is a versatile mechanical system used for the horizontal or inclined transportation of flour, grains, or other materials. It consists of a rotating helical screw blade, known as an auger, enclosed in a tube or trough. As the screw turns, it moves materials along the conveyor, facilitating the efficient and controlled transfer of wheat or flour between different processing stages within the mill. Screw conveyors are integral in optimizing material flow and streamlining the milling operation.
