Chain Disc Feed Conveyor Chain

The Chain Disc Feed Conveyor Chain is the primary moving component inside an enclosed chain-disc feeding system. It combines a high-strength steel chain with regularly spaced polymer carrier discs that move dry livestock feed through tubular conveying circuits.

As the chain travels through the pipeline, each carrier disc pushes feed forward while maintaining controlled spacing between material sections. This operating principle allows feed to move through straight pipes, horizontal sections, vertical changes and multiple corners within commercial pig farm feeding systems.

Reference PigTek systems use surface-hardened alloy chain with high tensile strength and solid nylon discs molded around the chain links. Completely enclosed molded discs help maintain consistent spacing and reduce the risk of individual discs becoming loose during long-term operation.

Chain diameter, carrier disc diameter, disc spacing, chain length and connecting links can be configured according to conveyor tube size, drive unit, corner design and project requirements.

• High-Tensile Chain: Surface-hardened or heat-treated steel chain provides resistance to stretching and mechanical fatigue under continuous conveying loads.
• Molded Nylon Carrier Discs: Wear-resistant polymer discs move feed efficiently through the conveying pipe.
• Whole-Link Disc Construction: Suitable designs mold the nylon disc around the complete chain link for improved retention and consistent spacing.
• Stable Disc Spacing: Uniform carrier spacing helps maintain smooth feed movement and predictable system capacity.
• Low-Friction Conveying: Smooth polymer discs reduce direct metal contact with the pipe wall and support efficient chain travel.
• Flexible Circuit Routing: The articulated chain can travel through multiple corner units in horizontal and vertical feed-line layouts.
• Suitable for Long Feed Lines: Properly engineered systems can cover long conveying circuits across large livestock buildings.
• Replaceable Chain Sections: Hardened connecting links can be used to join or replace chain sections during installation and maintenance.
• Commercial Farm Durability: Designed for continuous use in farrowing, gestation, nursery and finishing facilities.
• Custom Specifications: Chain size, disc diameter, spacing and total length are available according to project requirements.

• Steel Chain Links: Load-bearing links transfer pulling force from the drive unit throughout the feed circuit.
• Nylon Carrier Discs: Molded discs push feed through the tubular conveyor.
• Disc-to-Chain Interface: Injection-molded construction provides secure positioning of the disc around selected chain links.
• Connecting Link: Hardened open or detachable connector allows separate chain sections to be joined during installation or repair.
• Directional Disc Profile: Disc geometry is matched to the conveyor pipe and corner-wheel design for smooth movement.
• Protective Surface Treatment: Suitable chain surfaces can be treated or plated to improve durability in livestock farm environments.

The conveyor chain forms a continuous loop inside the feed transport pipeline. A motor-driven sprocket engages the chain and pulls it through the complete conveying circuit.

As the chain moves, the carrier discs sweep dry feed forward through the tube. Feed is transported between consecutive discs until it reaches an open drop outlet, feed dispenser, hopper or other discharge point.

At corners, the chain passes around guide wheels designed to maintain alignment and minimize resistance. Correct chain tension keeps the links and carrier discs properly engaged with the drive and corner wheels.

A correctly matched chain, disc, pipe and drive configuration provides stable feed transport while helping reduce feed segregation, excessive mechanical damage and unnecessary operating resistance.

System Compatibility: Confirm conveyor tube diameter, corner-wheel dimensions, drive sprocket profile and existing chain specification before installation.

Chain Direction: Directional carrier discs should be installed in the correct orientation according to the conveyor design and drive direction.

Chain Connection: Use the specified hardened connecting link when joining chain sections. Confirm that the connector is correctly closed and moves freely through the drive and corners.

Chain Tension: Set the correct tension before commissioning. Excessive tension can increase component wear, while insufficient tension can cause unstable engagement and irregular movement.

Initial Test: Run the empty system first and verify smooth movement through all straight sections, corners and the drive unit before introducing feed.

Routine Inspection: Periodically check the chain for elongation, damaged links, loose or worn discs and abnormal wear around connecting links.

System Maintenance: Inspect drive sprockets, corner wheels and chain tension at the same time. Replacing worn mating components helps prevent accelerated wear of a new conveyor chain.

In a typical commercial pig farm, the chain disc conveyor forms a continuous loop between the feed silo, drive unit, multiple corner assemblies and feed drops located throughout the livestock buildings.

Long circuits can supply several production areas while allowing the pipeline to change direction around building columns, pen layouts and other livestock equipment. Chain and disc dimensions must remain compatible with the pipe, corners and drive unit throughout the complete circuit.

For retrofit projects, compatible adapters and matched replacement chain configurations can allow existing tubular feed circuits to remain in service while worn or obsolete conveying components are upgraded.

Q: What is a chain disc feed conveyor chain?

A: It is a continuous steel chain fitted with regularly spaced polymer carrier discs. The chain travels inside a tube and moves livestock feed around the conveying circuit.

Q: Why are nylon discs used?

A: Nylon provides good wear resistance, mechanical strength and relatively low friction when moving through suitable feed conveyor tubing and corners.

Q: What is the advantage of molding the disc around the complete chain link?

A: Whole-link molding helps secure the disc to the chain and maintain consistent spacing, reducing the risk of individual carrier discs becoming loose during operation.

Q: Can damaged chain sections be replaced?

A: Yes. Suitable hardened connector links allow damaged or worn sections to be removed and replacement chain sections to be installed.

Q: Can the chain pass through multiple corners?

A: Yes. Chain-disc systems are designed for circuits with multiple directional changes. The allowable number of corners depends on total circuit length, drive capacity and system design.

Q: Can it replace the chain in an existing feed system?

A: Replacement is possible when the chain pitch, disc diameter, disc spacing, pipe size, drive sprocket and corner components are compatible. Existing system dimensions should be confirmed before ordering.

Q: What information is required for a quotation?

A: Please provide conveyor tube diameter, chain link dimensions, carrier disc diameter, disc spacing, total required length, drive unit type, corner configuration and photos or drawings of the existing system when replacement compatibility is required.
