Goldlong Machinery And Engineering Co., Ltd. designs and builds feed processing lines from individual machines to complete turn-key plants. From our own 14,000 m² manufacturing facility in Liyang, Jiangsu, China, we manufacture grinding, mixing, pelleting, extruding, cleaning, cooling, screening, liquid coating and conveying equipment for poultry feed, livestock feed, aqua feed, premix, pet food and biomass applications. As Custom Feed Processing Machinery Manufacturers, we combine equipment supply with process design, installation, commissioning, operator training and after-sales technical support.
The Product Center is organised around the main process stages of a feed plant. This allows us to match each machine to its duty and also coordinate the whole line from one supplier.
| Product line | What we supply | Typical application fit |
|---|---|---|
| Pellet Mill | Ring die pellet mills with stainless steel feeder, conditioner or DDC, gear drive and overload protection. | Poultry, livestock, aquatic and biomass pellet production where die size, conditioning time and throughput must be matched. |
| Hammer Mill | SFSP series, tear circle, wide type and vertical pulverizer grinders with balanced rotors and wear-resistant hammers. | Coarse and fine grinding of corn, grains, soybean meal and other raw materials with controlled particle size distribution. |
| Mixer | Double shaft high-efficiency mixers, stainless steel single shaft paddle mixers and ribbon mixers. | Mash feed, premix, aqua feed and additive blending with uniform liquid addition and low segregation. |
| Extruder | Extrusion systems for gelatinized and expanded feed products. | Floating and sinking aqua feed, pet food and specialty feed requiring controlled starch cooking. |
| Pre-Cleaner | Rotary and powder cleaning sieves for raw material intake and pre-grinding treatment. | Removal of stones, dust, fines and oversize impurities before grinding and pelleting. |
| Cooler | Counterflow or vertical coolers for pellets and extruded products. | Reducing pellet temperature and moisture after pelleting or extrusion to stabilize finished feed. |
| Crumbler | Double roll crushers for controlled size reduction of cooled pellets. | Production of crumble feed for chicks, piglets and other young animals. |
| Rotary Sifter | Rotary screens and grading sifters for pellets, crumbles and powders. | Removal of fines and on-spec separation before bagging or bulk loading. |
| Oil and Liquid Adding System | Spray systems for post-pellet coating with oils, molasses, flavors and liquid additives. | Enriching pellets with fats and liquids while maintaining uniform coating and avoiding fines buildup. |
| Bucket Elevator and Conveyor | Vertical bucket elevators and belt, screw or chain conveyors for raw material and finished feed. | Connecting process machines and bins with gentle handling and stable flow. |
| Other Auxiliary | Dust collectors, gates, bins, discharge devices, magnet separators and supporting equipment. | Completing the process line, protecting machines from metal debris and controlling dust. |
| Spare Parts | Ring dies, rollers, hammers, screens, seals, bearings and critical replacement components. | Minimizing downtime and keeping production running between scheduled maintenance windows. |
We arrange equipment by process stage so the machinery range supports a logical material flow from raw material intake to finished feed bagging or bulk loading.
The current model range is shown on our Pellet Mill, Hammer Mill and Mixer pages. We configure the selected model to the duty and integrate it with the surrounding line.
Line design starts with raw material and formulation, not with a fixed equipment list. We ask for the starting ingredients, target capacity, pellet diameter, expected moisture and the level of automation required. Engineering then selects the process path, machine sizes, conveying route, conditioning and post-pellet coating steps.
For turn-key projects we supply the electrical control system with the line. We configure motor control, interlocking, batching logic and monitoring around your plant layout and operating method. The same control package can also be adapted to existing equipment where the project requires a line upgrade rather than a new building.
Each proposal defines the scope boundary: equipment supply, mechanical installation, electrical connection, steel structure, ducting and commissioning. We use our factory quality control and project coordination to meet agreed delivery dates. At handover, we train operators and maintenance staff, provide technical documentation and agree a spare-parts plan.
To prepare a configuration and quotation, we work from the following project information. The more complete the input, the closer the proposal is to your real operating conditions.
Yes. We sell individual machines and plant sections as well as complete turn-key projects. The proposal will show the machine, its connection points and the support needed to install it into an existing process.
We need the raw materials, final feed type and formula direction, target capacity in tons per hour, pellet or crumble size, available utilities and the desired automation level. With these inputs we can prepare a process flow, equipment list and budget configuration.
Our processing equipment is used in poultry and livestock feed, aquatic feed, premix, pet food, grain storage and biomass energy projects. We adapt the material contact surfaces, conditioner options and post-processing stages to the specific product.
We support installation and commissioning with technical documentation, remote diagnostics and, where required, on-site supervision. Operator training covers machine operation, maintenance routines and process adjustment so the local team can run the plant independently.
The most important spares are ring dies, roller shells, hammers, screens, seals and drive belts. We prepare a recommended spare-parts list with each line and keep common wear parts available for rapid dispatch.
