    Feed Extruder Machine: Premium Aqua and Pet Feed Explained

    Why Thermal Extrusion Sets the Standard for Aqua and Pet Feed Fish, shrimp, dogs and cats share one nutritional reality: they only benefit from what they can digest.

    Animal Feed Mixer Machine: How to Choose for Uniform Batches

    Every batch of feed is only as good as its weakest scoop. When a few grams of vitamin premix, trace minerals, or a medicated additive land unevenly in a ration, some animals receive too little while others receive too much. Choosing the right animal feed mixer machine is therefore a nutrition decis...

Manufacturer of Custom Animal Feed Pellet Machines

As a Custom Animal Feed Pellet Machine supplier, Goldlong Machinery And Engineering Co., Ltd. designs and builds the SZLH ring die pellet mill series for poultry, livestock, aqua feed and biomass projects. We are a China-based manufacturer operating from a 14,000 m² production facility, and we supply either individual pellet mills or complete feed milling lines on a turn-key basis.

Our engineering scope starts with process design and continues through manufacturing, installation, commissioning, operator training and after-sales support. This is why a Goldlong pellet mill is quoted as a production asset with a defined capacity, conditioning performance, safety protection and line interface, not as a standalone machine.

Pellet Mill Range and Application Fit

We currently offer three SZLH configurations built around the same gear drive and ring die platform. Each version is matched to a different conditioning duty and product group.

  • SZLH High-Grade Poultry Feed Pellet Mill — an optimized rotor and wear-resistant die combination for rapid, uniform pelleting. It is suitable for pig, chicken, duck, cattle and sheep feed and fits medium and large feed plants and breeding bases.
  • SZLH Poultry Feed Pellet Mill With DDC and Conditioner — combines differential speed and single-shaft conditioning for uniform humidification, heating and thorough steam mixing. This version is intended for high-grade livestock, poultry and aquatic feed lines.
  • SZLH High-Grade Aqua Feed Pellet Mill — uses screw extrusion plus ring die technology to produce dense, stable pellets for fish, shrimp and crab feed. Temperature and pressure monitoring, adjustable pellet size and food-grade stainless steel make it suitable for dedicated aquatic feed production.

Typical SZLH Sizing Data

Model Typical Application Capacity (t/h) Main Motor (kW) Die Inner Dia (mm) Feeder / Conditioner (kW)
SZLH320 Poultry and livestock farm lines 2–5 37 320 0.75 / 2.2
SZLH400 Medium-scale feed mills 3–10 75 / 90 400 1.5 / 5.5
SZLH508 Commercial feed plants 5–20 132 / 160 508 1.5 / 7.5
SZLH678 High-throughput feed lines 5–25 200 / 220 / 250 672 2.2 / 15
SZLH768 Large industrial feed mills 10–36 250 / 280 / 315 762 2.2 / 15

Capacity values are based on typical poultry feed formulations with adequate steam conditioning. The final operating point is set during proposal engineering from the customer formula, moisture, die specification and steam supply.

Engineering Features Configured for Your Process

  • Stainless steel feeder with variable pitch anti-bridging mechanism and frequency conversion speed control for consistent feeding.
  • Extended stainless steel reinforced conditioner with a dedicated steam inlet arrangement to extend conditioning and maturation time.
  • High-precision gear drive with SKF bearings and imported oil seals for stable transmission and lower noise.
  • Quick-release ring die clamp and serpentine spring coupling for efficient die changes and smoother running.
  • Stainless steel door cover and inclined chute for easier cleaning and longer service life.
  • Overload protection and external discharge mechanism to protect the main machine and simplify clearing.
  • External thin-oil lubrication system is standard on SZLH678 and SZLH768, and optional on other models.
  • Optional steam pipeline, two- or three-layer jacketed conditioner, ring die lifting device and electric automatic oiling.

The DDC version also includes iron removal protection before conditioning, plus an adjustable feeder speed to handle different feed varieties without compromising pellet quality.

Process Fit and Line Integration

A pellet mill works between upstream grinding and mixing and downstream cooling and screening. In a complete feed line, correctly sized Hammer Mill and Mixer equipment must supply mash with the right particle size and uniformity for the ring die.

We design the pellet mill as part of a material flow that includes pre-cleaning, grinding, mixing, conditioning, pelleting, cooling, crumbling, sifting and liquid addition. Because we manufacture this full range, we can match the mill to existing process equipment or supply a complete engineered line with one point of responsibility.

  • Poultry and livestock feed: high-grade poultry mill or DDC version depending on formulation complexity.
  • Aquatic feed: dedicated aqua mill for dense pellets, or DDC version when flexibility across species is required.
  • Biomass and custom applications: ring die configuration selected from raw material, moisture and required pellet density.

Quality Assurance and Project Delivery

Our own 14,000 m² manufacturing facility gives us direct control over production, assembly and quality management. ERP management tracks workshop operations, and comprehensive inspections are carried out before shipment covering performance, stability, safety and full system testing.

Project implementation follows a defined cooperation process: requirement communication, process design, solution confirmation, equipment manufacturing, on-site installation, commissioning and training, then ongoing support. Common wear parts and critical components are kept in stock for rapid dispatch.

We have delivered machinery and turn-key projects to markets including Russia, Romania, Indonesia, New Zealand, the Philippines, Bangladesh, Pakistan, Iran, Syria, Jordan, Saudi Arabia and Sudan. Our service team provides remote diagnostics, regular follow-up and 24-hour rapid response support.

Information We Use to Configure Your Solution

For a precise quotation and process design, send us the project data below. Our engineering team then selects the model, ring die hole pattern, conditioner length and control interface.

  • Target species and feed type: poultry, livestock, aqua, premix, pet food or biomass.
  • Required capacity in tons per hour and planned operating shifts per day.
  • Raw formula and key ingredients, including moisture and fat content.
  • Target pellet diameter, hardness or water stability requirements.
  • Steam pressure and boiler output, or whether the line must run without steam.
  • Available electrical voltage, frequency and plant layout constraints.
  • Desired automation level: local panel, PLC line control or remote monitoring.

Pellet Mill Project FAQs

What pellet mill capacities can Goldlong engineer?

We build SZLH models from SZLH320 to SZLH768, covering approximately 2–36 t/h in the high-grade poultry range. Project capacity depends on formula, moisture, conditioning and die selection, so we confirm the operating point during process design.

Can one pellet mill handle both poultry and aqua feed?

Our DDC and conditioner version is used for high-grade livestock, poultry and aquatic feed. For dedicated floating or sinking aquatic feed, the high-grade aqua pellet mill with screw extrusion plus ring die is the better fit because it provides adjustable pellet sizes and dense, water-stable pellets.

What should we prepare before sending an inquiry?

Provide the raw material formula, target capacity, pellet diameter, available steam and site electrical data. If a full line is planned, include upstream grinding and mixing steps as well as downstream cooling and screening.

Do you supply complete feed mills or only the pellet mill?

Both. We supply individual pellet mills and turn-key projects from design, installation and commissioning to training. We can include hammer mills, mixers, coolers, crumblers, rotary sifters and conveying systems as part of the same engineering package.

What after-sales support is included?

We commission the equipment, train operators, keep common spare parts in stock and provide rapid response support. Our service scope includes remote diagnostics, regular follow-up and technical consultation throughout the equipment lifecycle.
