A: Due to their excellent versatility and reliability, screw conveyors are widely used in:

1. Wood Processing: Sawmills and furniture factories use them to transport waste such as wood chips, sawdust, and bark.
2. Biomass Power Generation: Transporting wooden fuels and清理 combustion ash.
3. Pulp and Paper: Mixing pulping chemicals and conveying wood chips.
4. Environmental Treatment: Transporting dewatered sludge in wastewater treatment plants.
5. They are also commonly used in grain processing, building materials, chemical, and food industries, among others.

A: The main reasons for the widespread popularity of screw conveyors include:

1. Simple structure, reliable operation, and low maintenance costs.
2. Enclosed conveying prevents spillage and dust, meeting environmental requirements.
3. Low energy consumption, high conveying efficiency, and cost-effective operation.
4. Flexible layout, allowing horizontal, inclined, or vertical installation.
5. Wide applicability to various materials, including powders, granules, and semi-fluids.

A: The core components of a screw conveyor include:

1. Helical Blade (Auger): Serves as the propulsion element, responsible for pushing materials forward.
2. Conveying Trough (Trough/Casing): Provides an enclosed space to prevent material leakage and dust dispersion.
3. Drive Unit (Motor & Gearbox): Supplies power to the system and controls the rotation of the screw.
4. Inlet & Outlet: Enable continuous feeding and discharging of materials.

A: A screw conveyor is a conveying device that utilizes rotating helical blades to continuously move bulk materials within an enclosed trough. Its working principle can be vividly described as "a rotating screw pushing materials through a pipe." Despite its simple structure, it enables highly efficient and stable material handling.
