Technical Structure of SZLH558 Feed Pellet Granulator

By strengthening core components and optimizing internal space, the feed pellet granulator achieves long-term stable operation under heavy loads.

Feeding and Conditioning System

Variable Frequency Feeding System: The unit includes a screw feeder driven by a 1.5KW variable frequency motor. The control system automatically adjusts the speed in real-time based on the main motor’s load current. This design ensures even feeding and prevents clogging.

Multi-stage Stainless Steel Conditioner: The conditioner is made of 304 stainless steel and equipped with an 11KW motor. Raw materials mix thoroughly with saturated steam inside. This process fully gelatinizes starch and significantly improves material stickiness.

Ring Die and Pelletizing Chamber

Large Diameter Wear-resistant Ring Die: The feed pellet granulator ring die diameter is 558 mm. Parts are made of high-quality high-chromium stainless steel. The mold undergoes vacuum quenching treatment. This process ensures consistent hole sizes, which minimizes discharge resistance.

Roller and Cutter Assembly: Two sets of reinforced rollers are installed inside the chamber. The roller bearings connect to an automatic lubrication system. The position of the cutter assembly is flexible, allowing users to easily control the length of the pellets.

Drive and Transmission System

Precision Gear Direct Drive: The main shaft uses a two-stage hard-tooth surface grinding gear drive. Compared to belt drives, this structure reduces energy loss by about 15% and prevents slipping during heavy loads.

Premium Bearings and Cooling System: The transmission part uses imported bearings. The gearbox features an independent circulating lubrication and heat dissipation system. Combined with an oil filter, the system ensures clean oil and stable temperatures.

Overall Frame and Design

Heavy-duty base: The frame is welded from ultra-thick steel plates. The base undergoes tempering treatment to eliminate internal material stress. The low center of gravity minimizes shaking during operation, ensuring the frame stays stable even after long-term use.

Safety Protection Devices: A strong magnetic separator is installed at the inlet. The system also includes a pneumatic external discharge mechanism. In case of motor overload or other issues, the feed pellet granulator quickly discharges material to protect the main engine.

Feeding and Steam Cooking

A reliable speed control feeder sends the raw materials into the feed pellet granulator smoothly and evenly. Inside the stainless steel conditioner, high-temperature steam quickly heats and softens the ingredients. This deep cooking process makes the feed much easier for animals to digest. It also helps the mixed materials stick together perfectly for the next shaping step. You can control the steam flow easily to get the best results every time.

High Pressure Pressing

The well-conditioned raw materials then enter the heavy-duty pressing chamber. A fast-rotating ring die and strong rollers press these materials through small holes with great force. This heavy mechanical pressure instantly turns the loose powder into solid, hard feed pellets.

This key process ensures that every single piece has a smooth surface, a dense structure, and consistent high quality and a highly durable shape.

Cutting and Final Output

As the long sticks of hot feed come out of the ring die holes, sharp adjustable knives cut them into the exact right length. Operators can easily change the final pellet size by moving the position of these cutters. This simple and stable cutting system works quickly to deliver a large amount of premium feed in a short time.

The finished pellets are now ready for the final cooling stage and next packaging process and shipment storage.

Buyer’s Guide & Support Center

All your questions are answered here! Below are answers to frequently asked questions about the SZLH558 pellet granulator, providing you with comprehensive answers.

What are the floor requirements for installing this gear-driven machine?

→

Since SZLH558 feed pellet granulator is heavy equipment that vibrates during operation, it must be installed on a reinforced concrete floor. The concrete thickness should be at least 200mm to ensure long-term stability.

What should the saturated steam pressure be?

→

The steam pressure entering the conditioner should stay between 0.2-0.4MPa. Pressure that is too high will damage nutrients, while pressure that is too low will not cook the material properly.

How do I choose the ring die compression ratio based on raw materials?

→

We recommend a compression ratio of 1:8 to 1:10 for standard poultry and livestock feed. For high-fiber grass powder, we suggest a lower ratio of about 1:6 to ensure smooth discharge.

Can I manually control the automatic lubrication system?

→

Yes. The system defaults to automatic interval lubrication. You can also manually adjust the oiling frequency on the control cabinet based on production time to prevent bearings from overheating.

How long does it take to clean the pelleting chamber after a sudden clog?

→

This model features quick-disassembly devices and a pneumatic discharge mechanism. A skilled operator can usually finish cleaning and restart the machine within 15-30 minutes.

Can RICHI provide upgrade plans for old production lines?

→

Yes. Our engineers will provide customized plans based on your existing factory space and power load to ensure the new feed pellet granulator connects efficiently with your old system.
