Burried Scraper Chain Conveyor

Buried Scraper Chain Conveyor

A Buried Scraper Chain Conveyor, also known as an En-Masse Conveyor, is a type of material handling equipment designed for the efficient and enclosed transport of bulk materials. It uses a chain-driven system with attached scrapers or paddles that move the material through an enclosed trough. This system is highly effective for horizontal or inclined conveying of powdery, granular, and small lumpy materials.

Features of Buried Scraper Chain Conveyors

1. Versatile Material Handling:
   • Suitable for materials such as coal, ash, clinker, cement, limestone, grains, sand, and more.
   • Can handle materials with different flow properties, including abrasive, sticky, and fragile materials.
2. Enclosed Design:
   • Ensures minimal spillage and dust emission, making it environmentally friendly and cleaner to operate.
3. Compact Structure:
   • The enclosed trough allows for space-efficient installation in facilities with limited space.
4. Efficient Transport:
   • Can convey materials horizontally, vertically, or at an incline, providing flexibility for various layouts.
   • En-Masse Effect: Material moves uniformly as a solid column with minimal disturbance, reducing wear and tear.
5. Durable Construction:
   • Made from abrasion-resistant materials for long service life, even with highly abrasive materials.
   • Heavy-duty chains and paddles ensure consistent performance in demanding environments.
6. Energy Efficiency:
   • Operates with relatively low power consumption compared to other conveyor types.

How a Buried Scraper Chain Conveyor Works

• A continuous chain is fitted with scrapers or paddles that travel along a sealed trough.
• Bulk material enters the conveyor through an inlet and is moved forward by the scrapers.
• The material forms a solid column that moves together, ensuring efficient conveying.
• The chain is driven by a motorized drive unit and circulates within the conveyor’s housing.

Applications of Buried Scraper Chain Conveyors

1. Power Plants:
   • Ash Handling: Transporting bottom ash and fly ash from boilers to silos or disposal areas.
   • Coal Handling: Moving coal from storage to feeding systems.
2. Cement Industry:
   • Conveying materials like clinker, gypsum, raw meal, and finished cement.
3. Biomass and Waste-to-Energy Plants:
   • Efficient transport of biomass ash, slag, and other residues.
4. Chemical and Fertilizer Plants:
   • Handling powdery and granular materials like fertilizers, chemicals, and phosphates.
5. Food and Grain Industry:
   • Transporting grains, sugar, salt, and other food-grade materials.
6. Mining and Aggregate Industry:
   • Moving minerals, ores, sand, and crushed stone.

Advantages of Buried Scraper Chain Conveyors

1. High Efficiency:
   • Capable of transporting large volumes of material over long distances.
2. Reduced Maintenance:
   • Durable components minimize the frequency of repairs and replacements.
3. Customizable Design:
   • Available in various sizes, materials, and configurations to suit specific applications.
4. Dust-Free Operation:
   • Fully enclosed design prevents dust leakage, ensuring a cleaner work environment.
5. Cost-Effective:
   • Low operational and maintenance costs compared to alternative conveying systems.
6. Flexibility:
   • Can be adapted to handle different material types and flow rates.

Key Design Considerations

1. Material Characteristics:
   • Flowability, abrasiveness, moisture content, and temperature of the material.
2. Conveyor Layout:
   • Horizontal, inclined, or vertical transport requirements.
3. Trough and Chain Material:
   • Choose abrasion-resistant materials for handling abrasive materials.
4. Capacity and Speed:
   • Designed to match the required throughput and flow rate of the material.
5. Power Requirements:
   • Motor and drive system should be designed to handle the load efficiently.

Maintenance Tips for Buried Scraper Chain Conveyors

1. Chain Tensioning:
   • Regularly inspect and adjust chain tension to prevent slack and wear.
2. Lubrication:
   • Ensure chains and moving parts are properly lubricated to reduce friction.
3. Wear Monitoring:
   • Inspect chains, paddles, and trough linings for wear and replace as needed.
4. Cleaning:
   • Periodically clean the conveyor to prevent material buildup that could hinder performance.
5. Drive System Inspection:
   • Check motors, gearboxes, and drive shafts for proper operation.

Conclusion

The Buried Scraper Chain Conveyor is a robust and versatile solution for handling bulk materials in a wide range of industries. Its ability to operate in challenging conditions, transport materials over long distances, and maintain a clean, dust-free operation makes it an essential tool for efficient material handling.
