Custom Feed Machinery Spare Parts Manufacturers

Spare Parts Designed Around the Feed Line

At Goldlong Machinery And Engineering Co., Ltd., we are Custom Feed Machinery Spare Parts Manufacturers with our own 14,000 m² production facility in Liyang, Jiangsu, China. We supply replacement dies, roller assemblies, shafts, gears, couplings and clamps for feed mills, grain dryers and organic fertilizer lines. Because we build turnkey projects and complete machines as well, every part we produce is matched to the operating conditions of the original equipment.

For plants already running Goldlong lines or third-party machinery, we are a single supplier for standard and custom-machined components. Our scope covers wear parts that affect pellet quality and throughput, plus drivetrain and structural items that keep your line running without unplanned stops.

Spare Parts Range at a Glance

This range supports pellet mills, hammer mills, mixers, extruders, coolers, crumbler and conveying equipment. The table shows where each component is used and what we need to make it a direct replacement.

Wear Parts Engineered for Pelleting Duty

These wear parts are designed for ring-die pellet mills, including the Pellet Mill range. For high-utilization plants, we suggest pairing dies with roller shells or assemblies as a matched set. This keeps pressure even across the die face, avoids premature wear and stabilizes energy consumption.

Drivetrain and Structural Components

Gears, pinions, couplings, quill shafts, main shafts with hold plate and die clamps handle torque and maintain alignment. We produce these components from alloy steel with machining and heat treatment matched to the original design.

• Quill shaft: carries the ring die and transmits main drive torque.
• Main shaft with hold plate: supports the die or rotor assembly and maintains alignment.
• Gear and pinion: for gearbox and drive units, supplied as pairs where required.
• Coupling: connects motor and reducer shafts to the main drive.
• Die clamp: holds the die against the quill shaft flange with the correct bolt pattern.

Materials, Machining and Quality Control

Spare parts are selected for wear resistance, load-bearing capacity and precise fit. Workshop operations are managed through ERP, and every part is inspected before shipment covering performance, stability, safety and full system testing.

• Material and hardness selection based on working point and original specification.
• CNC machining and precision boring for die holes and shaft geometries.
• Dynamic balancing for rotating components.
• Pre-delivery inspection and test report package.

Configuration Options and Customisation

We machine components from customer drawings, samples or original part numbers. The most common custom variables are:

• Die hole diameter, effective length and compression ratio.
• Roller shell width, surface texture, hardness and coating.
• Shaft length, spline or flange dimensions, keyways and bearing seat tolerance.
• Gear module, tooth count, pressure angle and exact bore.
• Sealing and bearing specification for dusty or high-temperature operation.

Project Support and After-Sales Service

Spare parts supply is part of our turnkey scope, from requirement analysis, process design and equipment manufacturing through installation, commissioning and training. Common wear parts and critical components are held in stock for immediate dispatch, reducing downtime. We also provide remote diagnostics, rapid response support and maintenance guidance for continuous operation.

For complete lines and equipment, see our Product Center. We support poultry, livestock, aqua feed, grain storage and biomass projects across Europe, Asia, Africa and beyond.

Information We Use to Configure Your Solution

To prepare a precise quotation and drawing, we work from a combination of original equipment data and operating conditions:

• Machine brand, model, year and original part number.
• Part drawing, worn sample, or dimensional sketch with key measurements.
• For dies: pellet diameter, die thickness, working width, hole pattern and compression ratio.
• For rollers: diameter, width, surface profile, hardness requirement and bearing size.
• For shafts and gears: length, spline or module data, bore sizes, keyways and material grade.
• Production parameters: raw material type, moisture, target throughput and operating hours.
• Delivery scope: single part, matched set, or replacement with installation guidance.

Frequently Asked Questions

Which spare parts do you keep in stock?

Common wear parts and critical components, including ring dies, roller shells, roller assemblies, shafts, gears, couplings and clamps, are available for rapid dispatch. For slower-moving items, we schedule production once the exact specification is confirmed.

Can you make spare parts for another manufacturer's pellet machine?

Yes. We regularly machine to customer drawings or against worn samples. Provide the machine model and original part details, and we confirm feasibility, material, hardness and delivery before quoting.

What die information do you need for a quotation?

We need the pellet mill model, required pellet diameter, die thickness or effective working width, hole pattern, compression ratio and formula type. Photographs and measurements of the existing die speed up the process.

How is quality checked before shipment?

ERP-controlled workshop management, in-process inspection and a comprehensive pre-shipment check cover performance, stability, safety and full system testing. The final report accompanies the parts.

Do you support installation and commissioning?

Our after-sales team provides installation and commissioning support, operator training and maintenance guidance. For fast replacements, remote diagnostics help your team complete the job confidently with minimal line downtime.

Can spare parts be included in a turnkey feed project?

Yes. We supply recommended spare part packages for every turnkey line we design, so you start with the right wear parts, critical components and documentation for independent operation.
