Screw conveyors are a type of material handling equipment that use a rotating screw or auger to move goods and products from one place to another. They are commonly used in industries such as agriculture, food processing, mining, and construction to transport materials such as grain, powders, and bulk solids.
Screw conveyors consist of a screw or helical blade that rotates within a trough or tube, pushing and moving material along the length of the conveyor. The screw is usually powered by an electric motor and can be designed to run at different speeds to control the rate of material flow.
Screw conveyors can be configured in various ways to suit different applications. They can be horizontal or inclined, and the trough or tube can be designed to have different shapes, such as U-shaped or tubular. They can also be equipped with different types of screw blades, such as standard, ribbon, or paddle, depending on the material being transported.
Screw conveyors are particularly useful for handling materials that are prone to segregation or degradation, as the gentle and continuous movement of the screw helps to prevent the material from separating or breaking apart. They can also be used to mix, blend, and heat materials in some applications.
