   • Applications: Ideal for semi-dry, granular, or powdered materials like cement, fly ash, or food products.
   • Advantages: Compact design, can handle sticky materials, and suitable for enclosed transport.
3. Bucket Elevators:
   • Description: Use a series of buckets attached to a belt or chain to move materials vertically.
   • Applications: Transport materials like grains, cement, or ash into silos or hoppers.
   • Advantages: Space-saving vertical design, high capacity, and customizable height.
4. Drag Chain Conveyors:
   • Description: Use a chain with paddles or flights to drag material along a trough.
   • Applications: Efficient for abrasive, hot, or sticky materials like clinker or ash.
   • Advantages: Rugged design, enclosed operation, and handles high temperatures.
5. Pneumatic Conveying Systems:
   • Description: Use air pressure or vacuum to transport fine, powdered, or granular materials through pipes.
   • Applications: Common in cement plants, food processing, and chemical industries.
   • Advantages: Dust-free, suitable for complex layouts, and handles fragile materials gently.
6. Vibratory Conveyors:
   • Description: Use vibration to move materials along a trough or tray.
