Overview:
A scraper conveyor is a type of mechanical conveying system used to move bulk materials, typically in a horizontal or slightly inclined direction. It is widely used in industries such as mining, agriculture, cement, and chemical processing. The conveyor consists of a trough or tube with a series of scrapers or flights attached to a chain or cable, which drags the material along the trough.
Key Components:
1.Trough/Tube: The enclosed or open channel through which materials are transported.
2. Scrapers/Flights: Metal or plastic blades attached to the chain or cable that push or pull the material.
3. Chain/Cable: The driving mechanism that moves the scrapers along the trough.
4. Drive Unit: The motor and gearbox that power the conveyor.
5. Tail Section: The end of the conveyor where the chain or cable returns.
6. Tensioning Device: Adjusts the tension in the chain or cable to ensure smooth operation.
1.En-Masse Conveyor: Designed for gentle handling of materials, often used in food processing and agriculture.
2. Heavy-Duty Scraper Conveyor: Built for rugged applications, such as mining and cement industries.
3. Tubular Scraper Conveyor: Features a circular tube for enclosed material transport, reducing dust and spillage.
Applications:
Mining: Transporting coal, ore, and other minerals.
Agriculture: Moving grain, feed, and other agricultural products.
Cement Industry: Handling raw materials and finished products.
Chemical Processing: Conveying powders, granules, and other bulk materials.
Efficient handling of bulk materials.
Can operate in harsh environments.
Enclosed designs reduce dust and contamination.
Low maintenance and long service life.
Regular inspection and maintenance are crucial for optimal performance. Key maintenance tasks include:
Checking and adjusting chain tension.
Lubricating moving parts.
Inspecting scrapers and replacing worn components.
Monitoring drive unit performance.
Safety:
Ensure proper guarding of moving parts.
Follow lockout/tagout procedures during maintenance.
Regularly inspect for wear and tear to prevent failures.
Conclusion:
Scraper conveyors are versatile and reliable solutions for bulk material handling across various industries. Proper selection, installation, and maintenance are essential for maximizing efficiency and longevity.
