what kind of screw conveyor used in wood handling?

In wood handling, the following types of screw conveyors are commonly used:

1. **U-Trough Screw Conveyors**: These are effective for moving wood chips, sawdust, and other bulk wood materials. Their design allows for easier access for maintenance.

2. **Tubular Screw Conveyors**: Suitable for transporting finer wood particles and sawdust while minimizing dust and spillage.

3. **Shaftless Screw Conveyors**: Ideal for handling sticky or bulky materials like wood shavings and chips, as they can prevent material build-up around a shaft.

4. **Inclined Screw Conveyors**: Often used for elevating wood materials from one level to another, such as from a chipper to a drying area.

These conveyors are chosen based on the specific wood products being handled and the required transport distance and angle.
