Types of Conveyor Chains
  • Roller Chains: Commonly used for power transmission, made of a series of rollers that rotate around a sprocket.
  • Block Chains: Often used in inclined or vertical applications; they consist of block-shaped links.
  • Plate Chains: Used in heavy-duty applications; these chains have flat plates that allow for stable load support.
  • Pin Chains: Features a pin that runs through a series of connected links, allowing flexibility and strength.
  • Modular Plastic Chains: Made of plastic, they are lighter and resistant to corrosion; commonly used in food processing and packaging.
Key Components
  • Links: Individual components that make up the chain.
  • Pins: Connect links and allow rotation.
  • Sprockets: Gear-like wheels that the chain loops around, facilitating movement.
  • Guides: Assist in the alignment and support of the chain during operation.
Measurements and Specifications
  • Pitch: The distance between the centers of adjacent links, typically measured in inches or millimeters. Common pitches include 1/2", 3/4", and 1".
  • Example: For a 1" pitch roller chain, the center-to-center distance between the rollers is 1 inch.
  • Width: The width of the chain, measured from the outer edges of the side plates.
  • Example: A standard roller chain may have a width of 0.75 inches.
  • Working Load Limit (WLL): The maximum load the chain can safely carry.
  • Example: A chain with a WLL of 2,000 lbs should not be subjected to loads exceeding this limit.
  • Strength: The tensile strength of the chain, often measured in pounds or newtons.
  • Example: A heavy-duty chain may have a tensile strength of 10,000 lbs.
Calculation of Load Capacity
  • To determine the load capacity of a conveyor chain, you can use the following formula:
  • Load Capacity=WLL × Number of Chains

Design Elements

Standard Scraper Chains

ICC can provide a range of conveyor chains with attachments fitting metal scrapers. Our standard scraper conveyor chain features a riveted construction, hardened and tempered link plates and case-hardened pins and bushes. The chain also features anti-rotation flats on the ends to improve efficiency and minimise wear. Welded pins and bushes and higher specification side plate materials can also be supplied for more demanding applications.

  • Chain Links
  • Construction: Links are typically constructed from steel and can be designed in various shapes, including oval, round, or flat profiles.
  • Interconnection: Links are connected by pins, which allow for rotational movement and flexibility in operation.
Scraper Attachments
Types of Scrapers:
  • Conventional Scrapers: Designed for general applications, typically featuring a flat edge for effective material movement.
  • Specialized Scrapers: Custom shapes for specific materials (e.g., wedge-shaped for heavy clays).
  • Attachment Method: Scrapers can be bolted, welded, or snap-fitted onto the chain links.
Chain Pitch
  • Definition: The distance between the centers of adjacent links, influencing the chain's strength and load capacity.
  • Standard Sizes: Common pitches range from 1 inch to 2 inches, with custom sizes available based on application.
Types of Scraper Chains
Single-Strand Chains
  • Use Case: Best for lighter loads and simpler conveyor designs.
  • Design: Typically simpler, with a single row of links.
Double-Strand Chains
  • Use Case: Suitable for heavy-duty applications requiring higher load capacity.
  • Design: Two parallel rows of links providing increased strength and stability.
Heavy-Duty Chains
  • Use Case: Designed for extreme environments, such as mining and heavy industrial application
  • Features: Thicker links, reinforced connections, and often heat-treated for added strength.
Material Selection
Steel Alloys
  • High Carbon Steel: Commonly used for its strength and wear resistance.
  • Alloy Steels: Can be alloyed with elements like chromium and nickel for enhanced toughness and corrosion resistance.
Stainless Steel
  • Corrosion Resistance: Ideal for applications in corrosive environments, such as food processing and chemical handling.
  • Grades: Common grades include 304 and 316 stainless steel.
Applications
Mining
  • Function: Used in haulage systems to transport ore and coal from extraction points to processing areas.
  • Features: Often includes wear-resistant coatings for durability.
Waste Management
  • Function: Used in conveyor systems for municipal solid waste, recycling, and composting.
  • Importance: Reliable performance under heavy loads and abrasive materials.
Agriculture
  • Function: Employed in grain handling systems, including silos and elevators.
  • Benefits: Efficient movement of bulk agricultural products.
Manufacturing and Assembly Lines
  • Function: Integrated into conveyor systems for efficient material handling.
  • Design: Can be customized to specific layouts and production requirements.
Maintenance and Inspection
Lubrication
  • Types of Lubricants: Grease and oils are common, with options for food-grade lubricants in food processing.
  • Frequency: Regular lubrication schedules should be established based on operational hours and conditions.
Alignment
  • Importance: Proper alignment ensures even wear and reduces stress on links and scrapers.
  • Methods: Use alignment tools or visual inspections to verify the straightness of the chain path.
Wear Inspection
  • Visual Checks: Regularly inspect for wear, deformation, or cracking of links and scrapers.
  • Measurements: Use gauges to measure wear on key components, replacing them as necessary.
Operational Considerations
Load Capacity
  • Determining Factors: The type of material, chain design, and operational speed affect the load capacity.
  • Safety Factor: Always calculate and include a safety margin based on operational needs.
Speed and Efficiency
  • Operational Speed: The speed of the chain should be optimized to prevent material spillage while ensuring efficient movement.
  • Monitoring: Use sensors or visual indicators to monitor performance and identify potential issues early.
Environmental Factors
  • Temperature: Extreme temperatures can affect material properties, particularly in plastics and rubber scrapers.
  • Chemical Exposure: Select materials resistant to the chemicals encountered in specific applications.
Innovations and Trends
Customization
  • Tailored Solutions: Increasing demand for custom-designed scraper chains to meet specific operational challenges.
  • Rapid Prototyping: Advances in manufacturing techniques allow for quicker iterations and more effective design modifications.
