The screw conveyor for powder transport (Screw Conveyor) is a specialized device used to transport powder, fine particles, and bulk materials such as flour, cement, plastic pellets, chemical powders, etc., horizontally, at an incline, or vertically. With stable operation, easy adjustment, and a fully enclosed design, it is an ideal solution for automated production lines in modern manufacturing.
⚙️ Basic Structure
– **Screw shaft (helical shaft)**: Made from carbon steel, stainless steel 304, or 316
– **Conveying tube**: Round or U-shaped, fully enclosed
– **Gear motor**: Stable transmission, flexible speed adjustment
– **Feed hopper**: Customizable based on installation space
– **Cleaning or discharge port**: Facilitates easy cleaning
✅ Key Advantages
– Efficient transport of powder, fine, or small granular materials
– Fully enclosed – dust-proof, ensuring food safety and hygiene
– Space-saving – flexible installation in vertical or inclined configurations
– Smooth operation, easy maintenance
– Customizable length, material, and configuration
📌 Practical Applications
🌾 **Food industry**: Flour, milk powder, coffee, pepper
🏗️ **Construction materials**: Cement, lime, fly ash
🧪 **Chemical industry**: PVC powder, activated carbon powder, fertilizer
♻️ **Recycling & environmental industry**: Sludge, plastic powder, fine solid waste
