Screw Conveyor

Screw Conveyor Function and Working Method

The Screw Conveyor operates through the rotation of a spiral blade, also known as a screw, which is housed within a trough. As the screw rotates, it creates a pushing force that moves the material forward along the trough. The rotational motion of the screw ensures that the material is transported efficiently and consistently. This method of material handling is particularly effective for moving materials that are difficult to transport using traditional belt conveyors, such as sticky or damp substances.

Screw Conveyor Material and Construction

The Screw Conveyor is constructed from either carbon steel or stainless steel (SS304), depending on the specific application and material requirements. Carbon steel provides robustness and durability for general-purpose applications, while stainless steel offers excellent corrosion resistance and hygiene, making it suitable for food-grade and chemical applications.

Screw Conveyor Key Features

• Function: Transport palm fruits, nuts, kernels, and other small-sized materials.

Screw Conveyor Applications

The Screw Conveyor is widely used in palm oil mills and processing plants for transporting palm fruits, nuts, kernels, and other by-products. It is typically installed between different processing stages, such as from the sterilization tank to the threshing machine, or from the kernel separation stage to the drying unit. Additionally, it finds applications in other industries for transporting grains, seeds, chemicals, and various bulk materials. Its design and specifications make it suitable for integration into both new and existing processing facilities, enhancing their overall efficiency and productivity.
