Screw Conveyor
Product description
A screw conveyor is a conveying equipment that pushes materials in
a closed shell by rotating screw blades. Its core structure
consists of a screw shaft, U-shaped or tubular material troughs, a
drive device and bearings. It can achieve material transmission in
horizontal, inclined (inclination Angle ≤20°) or vertical
directions. It has the advantages of compact structure and
space-saving, sealed conveying to prevent dust, and the conveying
capacity can be adjusted by rotational speed. It is often used in
industries such as grain processing, chemical engineering, and
building materials to convey powdered and granular materials.
However, it has poor adaptability to sticky or large pieces of
materials, and when conveying over long distances, it needs to be
arranged in sections. This kind of equipment occupies an important
position in industrial material transmission due to the high
efficiency of mechanical transmission and the flexibility of
structural design.
Working principle
The working principle of a screw conveyor is as follows: The drive
device rotates the screw shaft, causing the screw blades to rotate
synchronously. After the material enters the shell, it moves
axially and directionally under the combined action of the blade
thrust, the shell friction force and the centrifugal force (when
conveying at an inclined or vertical Angle). When conveying
horizontally, it is directly pushed by the blades; when conveying
at an inclined or vertical Angle, it needs to overcome gravity.
Among them, the friction between the shell and the material can
prevent the material from idling along with the blades, ensuring
the conveying efficiency. This principle makes it more adaptable to
powdery and granular materials, while when conveying viscous
materials, special structures such as variable-pitch blades need to
be adopted to avoid clogging.
Product characteristics
1. Compact structure: Small footprint, suitable for installation in
narrow Spaces.
2. Sealed and environmentally friendly: The fully enclosed shell
prevents dust leakage and is suitable for clean environments.
3. Flexible direction: It can be conveyed horizontally, at an
incline (≤20°) or vertically, and supports multi-stage rotation.
4. Controllable conveying: The conveying capacity can be adjusted
by rotational speed, making it suitable for quantitative conveying
of powdery/granular materials.
5. Easy maintenance: The components are simple, wear is easy to
inspect, and the replacement cost is low.
6. Obvious limitations: It is not suitable for sticky or large
pieces of materials. For long distances, it needs to be segmented.
The energy consumption for inclined conveying increases with
height.
