Twin Screw Extruder Machine
Product Introduction
What is Twin Screw Extruder Machine?
Capacity: 0.5-12 T/H
RICHI twin screw extruder is a machine that produces pellets continuously and steadily, with uniform diameter and a well‑cooked texture. These pellets are widely used in the high‑end feed market. The machine can handle high‑end floating fish feed, specialty aquatic feed, pet food, and similar products.
The whole machine can adapt to all kinds of complex, high‑nutrition formulations and delivers good shaping results. That’s why it’s a key piece of equipment for producing high‑quality feed.

Composition of Twin Screw Extruder Machine
The final quality of your pellets has a lot to do with the twin screw extruder machine‘s structure and the technology behind it. So we’ll break this machine down for you and give you a full picture of its main components.
Feeding System
This system has two main parts: an arch‑breaking device and a variable‑frequency feeder.
The arch‑breaking device uses blades to stir the raw materials, so they move evenly and smoothly into the conditioner. This stops high‑moisture or high‑oil materials from blocking the inlet during production. The variable‑frequency feeder adjusts the feed rate based on the current pelleting condition. That keeps the production flow steady and prevents the extruder from overloading or running empty.
Extrusion System
Extrusion is a crucial step in the production of high-end aquatic feed and pet food, forming the core of the entire pelleting process.
RICHI twin screw extruder machines come with a fully intermeshing, zero‑backlash twin‑screw design, paired with a bimetal liner inside the barrel. The twin screws distribute the shear force evenly within the chamber, giving you good control over both the cooking time and the expansion rate of the material.
Drive System
The motor is a key part of the power system – it supplies all the drive the machine needs. That keeps the twin‑screw extruder running for long periods without unexpected shutdowns due to fluctuations in production.
With that motor in place, you can adjust the screw speed freely to match different production requirements – whether you’re making aquatic feed, pet food, or other products.

Customer Cases of Twin Screw Extruder Machine
RICHI twin screw extruder machines have been sold to many countries and regions worldwide. We’ve helped tons of farmers and feed producers solve their feed processing headaches. Here are some real examples.
Advantages of Twin Screw Extruder Machine
The RICHI twin screw extruder machine comes loaded with high-quality core components. Once you start using it, you’ll really feel the difference it makes for your feed production.
We’ve equipped this twin screw extruder with a PLC and touchscreen control system. Key parameters can be adjusted directly—no complicated steps. Even if you’re new to feed production, you can get up to speed fast and run it like a pro. That means way fewer human errors.
Easy to Operate
The screw is the heart of the twin screw extruder machine. Ours is made of 38CrMoAl—a fully wear-resistant alloy. The barrel has a bimetallic liner, so wear resistance is solid. That means the machine stays stable even under heavy, nonstop production. Bearings are from FAG and SKF—top brands. So power transmission is reliable, failure rates are low, and you don’t have to stress about maintenance or downtime costs.
Reliable and Durable
Unlike single-screw designs, the fully intermeshing, zero-clearance twin-screw setup is the biggest advantage here. The two screws intermesh and spin in the same direction, creating steady, uniform shear and kneading inside the barrel. That stops sticking, slipping, and uneven cooking. Whether you’re dealing with high-oil or high-moisture ingredients, everything gets heated evenly.
Superior Structure
We’ve specially designed and optimized how power is distributed inside the barrel. That way, material gets just the right amount of shear, kneading, and heat in different zones—no local hot spots, no uneven cooking, no insufficient shearing. So in the same amount of time, our twin screw extruder machine gives you both higher quality and greater output.
Superior Feed Quality
Applications of Twin Screw Extruder Machine
RICHI’s twin screw extruder machines cover capacities from 0.5 T/H all the way to 12 T/H. Different models suit different needs. All of them handle pellet diameters from 0.6 mm to 20 mm. Here’s a quick summary to help you choose.
Small Pellet Production Plant
Suitable Model: SPHS75×2
Capacity: 0.5–1 T/H
Suitable For: Small feed pellet plant projects, start‑up pet food brands, and small‑to‑medium aquaculture support workshops.
Advantages:
The main motor runs at 55kW, keeping energy consumption low. The machine has a compact design and a small footprint, so it fits easily into smaller factory spaces. You can switch flexibly between producing floating aquatic feed, slow‑sinking feed, and small‑to‑medium formula pet food. That gives you high equipment utilization. In short, it’s a cost‑effective choice for small‑batch, high‑end extruded feed production.
Medium Pellet Production Plant
Suitable Model: SPHS120×2
Capacity: 1.5–4 T/H
Suitable For: Medium‑sized feed mills, regional brand suppliers, and emerging pet food processing plants.
Advantages:
Capacity jumps significantly compared to the smaller models, so you can comfortably cover medium‑to‑large production runs. It comes with a dedicated DC500‑244 conditioning system, which ensures thorough and even cooking of the material. You can produce water‑stable, highly palatable specialty aquatic feed with it, and it also handles high‑meat, high‑protein, and hypoallergenic pet food formulas really well. That helps boost final product quality and lock in more nutrients.
Medium‑to‑Large Pellet Production Plant
Suitable Model: SPHS150×2
Capacity: 5–6 T/H
Suitable For: Large‑scale feed companies, specialized aquaculture feed plants, and professional high‑end pet food manufacturers.
Advantages:
This model comes with a 200kW main motor and a large‑capacity DC600‑300 conditioner. Mixing, cooking, and expansion are all taken to a higher level. It handles demanding formulas with high fishmeal, high oil content, or fresh meat additions – without any trouble. The equipment supports long, continuous production runs, and a single operator can manage the whole system. That cuts labor costs significantly and matches the pace of industrialized, standardized high‑end feed production.
Large‑Scale Pellet Production Plant
Suitable Model: SPHS185×2
Capacity: 10–12 T/H
Suitable For: Large aquatic feed and pet food manufacturers that are leaders in their field.
Advantages:
The main motor delivers 355kW of power, giving you strong performance and high load capacity – perfect for filling very large orders on a continuous basis. It features a DC600‑300 differential speed conditioning system, which boosts material processing efficiency and ensures more uniform mixing. That makes it easy to handle all kinds of complex, premium formulations. The machine also comes with a fully automatic intelligent control system, so it runs steadily, quietly, and with a low failure rate. It’s an excellent match for high‑load, standardized, and even unattended production lines in large factories.

FAQ
Below are answers to common questions from past customers. You might have the same ones. If not, feel free to reach out anytime.
What’s the difference between single screw and twin screw extruder machine?
→
Single screw extruders are pickier about raw materials and don’t mix as well. They’re okay for standard feeds. Twin screw extruder machines can handle high-oil, high-moisture, and sticky materials. The two screws spin together, giving you stronger shear and more even cooking. So they’re better for high-end feed pellets.
If you’re planning to make high-value feed, a two screw extruder is the smarter choice.
What types of aquatic feed can a twin screw extruder machine mainly produce?
→
By adjusting moisture content, screw speed, and other parameters, you can switch between processes and produce multiple feed types.
Floating fish feed: For tilapia, salmon, trout, ornamental fish—surface feeders.
Sinking fish feed: For sturgeon, catfish, largemouth bass, flounder—bottom dwellers.
Shrimp and crab feed: Produces high-quality sinking feed for shrimp and crab farming.
Does the twin screw extrusion machine have any special raw material requirements?
→
Ourtwin screw extruder machine is highly versatile. It can handle all kinds of ingredients – corn, soybean meal, fish meal, wheat, and bran, for example. It also processes high‑moisture materials like fresh meat paste and wet fish meal, as well as high‑oil and high‑fat raw materials. The twin‑screw design does a great job of managing moisture during processing. It ensures even mixing and thorough cooking, so you don’t lose valuable nutrients.
What’s the warranty period?
