Multi-Circuit Chain Disc Feed System

The Multi-Circuit Chain Disc Feed System is an automated dry-feed conveying solution designed for commercial pig farms with multiple barns, production zones or feeding groups. It uses a continuous chain fitted with durable conveying discs to transport mash, crumbs, pellets and other suitable dry feeds through an enclosed pipe network.

Unlike a simple single-line conveyor, the multi-circuit configuration allows a farm to divide the feed distribution network into independent or coordinated conveying loops. Different circuits can serve gestation houses, farrowing rooms, nursery barns, finishing houses or other production areas according to the farm layout and feeding program.

The modular system can be integrated with feed silos, transfer hoppers, feed dispensers, automatic feeders, sensors and electronic controllers. Its flexible pipe routing makes it particularly suitable for large pig farm construction, existing barn modernization and complex steel structure building projects where feed must be transported around multiple corners and between different livestock houses.

• Multi-Circuit Feed Distribution: Multiple conveying loops can serve different livestock houses, production stages or feeding zones from a coordinated feed storage system.
• Flexible Pipe Routing: Straight pipes and corner assemblies allow the feed line to follow complex barn layouts and pass around structural columns, partitions and livestock equipment.
• Enclosed Feed Transport: Dry feed travels inside a closed pipe system, helping reduce contamination, feed loss and unnecessary exposure to the barn environment.
• Gentle Feed Conveying: Chain-mounted discs move feed through the pipeline with controlled mechanical action, suitable for mash, crumbs and compatible pellet feeds.
• Independent Circuit Control: Individual circuits can be operated according to feeding schedules, barn requirements or feed demand when equipped with suitable control equipment.
• Direct Silo Connection: The conveying system can be arranged from the feed silo or transfer hopper to indoor feeding points according to project design.
• Expandable System Architecture: Additional feed drops, dispensers, feeders or circuits can be considered during farm expansion, subject to system capacity and engineering requirements.
• Automation Ready: Compatible sensors, controllers and farm management equipment can be incorporated for automatic start-stop operation and feeding supervision.
• Low Routine Labor Requirement: Automated feed delivery reduces repetitive manual feed transport between silo areas and livestock houses.
• Suitable for Commercial Farms: Designed for intensive pig production facilities requiring reliable and repeatable feed distribution throughout daily production cycles.

• Feed Intake / Transfer Hopper: Receives dry feed from the silo or upstream feed handling equipment and introduces it into the conveying circuit.
• Chain and Disc Assembly: Continuous steel chain fitted with engineered polymer discs carries feed through the conveying pipes.
• Conveying Pipe: Enclosed tubular feed line forms the main transport route between storage and feeding points.
• Drive Unit: Electric motor and transmission assembly provide controlled movement of the chain-disc loop.
• Corner Assemblies: Guide the chain and discs smoothly through changes in direction within complex barn layouts.
• Chain Tensioning Device: Maintains suitable operating tension and compensates for normal changes occurring during long-term operation.
• Feed Outlets: Positioned at required feeding points to discharge feed into dispensers, hoppers or automatic feeders.
• Volumetric Dispensers: Optional transparent or enclosed dosing devices can provide controlled feed quantities for individual sows or designated pens.
• Drop Pipes: Transfer feed vertically from the main conveying line to feeders, troughs or dispensing equipment.
• Feed Sensors: Optional sensors detect feed presence or hopper filling status and communicate with the control system.
• Electrical Control Panel: Coordinates drive units, sensors, circuit operation and safety functions according to the selected automation level.
• Suspension and Support Components: Pipe clamps, brackets, hangers and structural supports secure the conveying line inside the livestock building.

Dry feed enters the system from a silo discharge, transfer hopper or metering device. When a feeding circuit starts, the drive unit pulls the continuous chain through the enclosed pipe network.

Discs mounted at regular intervals on the chain carry feed through horizontal, vertical and curved sections of the conveying circuit. Corner wheel assemblies guide the chain around changes in direction while maintaining continuous circulation.

As feed reaches designated outlets, it is discharged into volumetric dispensers, intermediate hoppers, automatic feeders or other feeding equipment. Feed level sensors can stop the circuit automatically when the required downstream filling condition is reached.

In a multi-circuit installation, separate conveying loops can supply different barns or production zones. Circuit operation can be scheduled independently or coordinated through a centralized controller according to farm management requirements.

System Planning: Confirm feed silo locations, barn dimensions, pen arrangement, required feeding points and production groups before determining the number and routing of conveying circuits.

Pipe Installation: Conveying pipes should be securely supported and correctly aligned. Suspension spacing and mounting brackets should be selected for the actual pig house or steel structure building.

Corner Installation: Corner assemblies should remain accessible for routine inspection and should be positioned to provide smooth chain movement without unnecessary changes in direction.

Drive and Tension Adjustment: The drive unit and chain tensioning system should be commissioned according to the completed circuit length and operating load.

Sensor Commissioning: Feed level sensors and automatic controls should be tested with the actual feeding equipment before normal livestock operation begins.

Routine Maintenance: Periodically inspect chain tension, conveying discs, corner wheels, bearings, drive components, pipe joints, feed outlets and electrical sensors. Remove accumulated feed or foreign material where necessary and replace worn components before they affect circuit performance.

Multi-Barn Pig Farm: One central feed storage area can supply several independent chain disc circuits serving gestation, farrowing, nursery and finishing buildings. Each circuit can be configured according to its own feed demand and feeding schedule.

Large Sow Farm: Multiple circuits can supply volumetric dispensers positioned above individual sow stalls or farrowing pens, allowing automated filling of a large number of feeding points.

Farm Modernization: The modular pipe conveyor concept is suitable for upgrading existing livestock buildings because routes can be designed around existing pens, columns, ventilation equipment and other farm infrastructure.

Q: What is the advantage of a multi-circuit chain disc system?
