Comparison Between Tubular and Trough Screw Conveyors
| Feature | Tubular Screw Conveyor | Trough Screw Conveyor (U-Type Screw Conveyor) |
|---|---|---|
| Structure | Round tubular casing with the screw shaft inside | U-shaped trough casing with the screw shaft inside |
| Advantages | Enclosed conveying to prevent dust and material loss, easy to clean, suitable for materials with poor flowability | Simple structure, easy to manufacture, low cost, easy maintenance, suitable for various materials |
| Disadvantages | Difficult to observe material flow, harder to repair in case of failure, not suitable for fragile materials | Prone to dust generation and material loss, not suitable for highly corrosive materials |
| Applications | Food, pharmaceuticals, chemicals, volatile materials, high-moisture materials | Cement, sand, stone, coal, agricultural products, construction materials |
| Material handling capability | Powder, fine granules, viscous materials | Granules, lumps, powder |
| Conveying efficiency | High | Medium |
| Investment cost | Lower | Higher |
| Durability | Good | Average |
| Ease of cleaning | More difficult | Easier |
Note: The above comparison is only relative and may vary depending on the specific design of each type of screw conveyor. Selecting the right type should be based on the properties of the material, required capacity, operating conditions, and investment budget.
