### Screw Conveyor
A **screw conveyor** is a mechanical device that uses the rotational movement of screw blades to achieve axial transportation of materials. It is widely used in industries such as chemical engineering, food processing, metallurgy, building materials, and mining, primarily for conveying powdery, granular, and small lumpy materials (e.g., cement, coal powder, sand, grains, etc.).
#### Structure and Working Principle
1. **Core Components**
- **Screw Shaft**: A central shaft with fixed screw blades (classified as solid screws, ribbon screws, paddle screws, etc.).
- **Trough**: A closed U-shaped or tubular housing that holds materials and guides the conveying direction.
- **Drive Unit**: An electric motor drives the screw shaft through a coupling or speed reducer.
- **Inlet/Outlet**: Located at opposite ends of the trough (typically the inlet at the lower end and the outlet at the higher end).
2. **Working Principle**
When the screw blades rotate, materials are pushed by the blades and friction from the trough's inner wall, moving axially along the screw shaft to achieve transportation from the inlet to the outlet.
#### Advantages
1. Simple and compact structure with small footprint, suitable for installation in narrow spaces.
2. Good sealing performance, preventing material dust from escaping or external contamination, ideal for high environmental requirements.
3. Capable of multi-point feeding and discharging, facilitating system integration.
4. Can simultaneously perform auxiliary functions such as mixing and stirring during transportation.
#### Application Scenarios
1. **Industrial Production**: Conveying powder and ore in chemical engineering; transporting cement and sand in building materials; handling ore and coal powder in metallurgy.
2. **Agriculture and Food Processing**: Transporting grains and beans in food storage; conveying pellet feed in feed processing.
3. **Environmental Protection**: Conveying sludge in wastewater treatment plants; handling solid waste in garbage disposal facilities.
4. **Logistics and Warehousing**: Short-distance loading/unloading of bulk materials in ports and docks.
