Powder Conveying Screw with Bunker

Description

Key Features:

1. Conveyor Type:

   • Screw Conveyor: The screw auger (also called an Archimedes screw) moves the powder through a tube or trough by rotating, providing continuous flow.

2. Capacity:

   • Customizable depending on the application; typically ranges from 500 kg/hr to several tons per hour depending on material and system size.

3. Material of Construction:

   • Screw Shaft & Housing: Typically made from stainless steel (304 or 316) for durability and hygiene, especially in the food and pharmaceutical industries.
   • Powder Flow Bunker/Hopper: Often made of stainless steel or Mild Steel for cost-effectiveness.

4. Dimensions:

   • Bunker sizes vary, but common configurations include 500L to 2000L bunkers to store powder for short or medium-term use.
   • Screw Diameter: Varies from 100 mm to 500 mm based on material size and flow rate.

5. Powder Handling:

   • Can handle dry powders, granules, or bulk solids.
   • Prevents segregation and dusting, ensuring smooth, consistent flow.

6. Motor and Power:

   • Equipped with a motorized drive ranging from 0.5 kW to 5 kW, adjustable speed to optimize powder movement.
   • Optional variable speed drives to fine-tune the flow rate for different powders.

7. Hopper/Bunker Features:

   • Vibration systems (optional) may be included to help facilitate powder flow and reduce clogging.
   • Level sensors to monitor the powder level inside the bunker and ensure a consistent feed.

8. Safety Features:

   • Explosion-proof motors (if handling flammable powders).
   • Overload protection to prevent motor damage.
   • Anti-jamming devices to ensure smooth operation.

9. Cleaning & Maintenance:

   • Easy access points for cleaning.
   • CIP (Clean-in-Place) option is available for hygienic operations, especially in the food or pharmaceutical sectors.

Applications:

• Food Processing: Transferring dry ingredients like flour, sugar, or spices.
• Pharmaceuticals: Conveying powders like active ingredients, excipients, or API (Active Pharmaceutical Ingredients).
• Chemicals: For transporting chemical powders or bulk materials in industrial plants.
• Plastic or Recycling Industries: Moving plastic pellets or other fine powders.

Advantages:

• Compact Design: Can be customized to fit within tight spaces.
• Efficient Powder Flow: Ensures smooth and continuous powder transfer with minimal wastage.
• Versatile: Suitable for a wide range of powders and granular materials.
• Minimal Dusting: The enclosed design reduces airborne dust, improving workplace safety.
