Do you really understand the spiral conveyor?
The screw conveyor, whether by its name or its compact physical structure, often gives users the mistaken impression that it may look impressive but isn’t very practical. However, this couldn’t be further from the truth—it’s actually a device that uses the rotation of a helical shaft to efficiently convey materials, capable of handling both horizontal and inclined transport tasks. Let’s now take a closer look at its structure and key features!
1. The primary structure of the screw conveyor consists of several key components, including the drive unit, head-end fittings, housing, helical central shaft, trough bottom plate, inlet and outlet ports, cover plates, base frame, and more. Below, we will introduce each of these components individually.
2. Drive Equipment: The primary options are either a harmonic drive or a hardened-gear reducer—both types of drive equipment. When designing, we aim to mount the drive unit as close as possible to the discharge end, ensuring that the entire screw assembly remains in tension during rotation.
3. The head end of the screw conveyor is equipped with a thrust bearing, primarily designed to withstand the axial forces generated during material transportation. 4. The body—typically U-shaped or O-shaped—is usually fitted with a weatherproof cover on its upper section. The body is commonly made from either stainless steel or carbon steel.
The spiral center shaft primarily uses stainless steel and carbon steel as its raw materials.
5.槽体底板: The primary materials are three types—wear-resistant plastic sheets, rubber sheets, and cast stone sheets.
6. Feed and Discharge Ports: These come in two shapes—square and round—but users can also choose the shape that best suits their needs.
