SYLH Series Ring Die Feed Pellet Mill – Product Introduction

1. Equipment Overview

The SYLH series ring die feed pellet mill is a rugged, high-capacity pelleting machine built for commercial feed production environments. With throughput reaching up to 20 tons per hour and main drive power ranging from 37 kW to 315 kW, this series supports medium to large-scale operations across the livestock, poultry, and aquaculture sectors.

Engineered for continuous heavy-load service, the SYLH series transforms diverse feed formulations into dense, uniform pellets with excellent durability and minimal fines—delivering consistent results shift after shift.

3. Key Product Highlights

Feature Advantage
Interchangeable ring dies Quick die change for pellet sizes from 0.5 mm to 12 mm—one machine serves poultry, livestock, and aquatic feeds
2, 3 or 4 roller options Match roller count to your ingredients; heavier materials benefit from more rollers for consistent compaction
Gear-driven main transmission Handles shock loads and continuous operation with less wear than belt drives—lower maintenance, higher uptime
304 stainless steel contact parts Resists corrosion from moisture and acidic ingredients; easy to clean and meets hygiene standards
Integrated conditioner Pre-conditioning with steam or molasses improves pellet quality and reduces die wear
Variable-speed feeder Precise feed rate adjustment to match the pelleting head, preventing overload or starvation

What this means for your operation:

  • Less downtime – Wear parts last longer and changeovers are straightforward

  • Better pellet quality – Uniform density and size reduce fines and improve animal intake

  • Lower energy cost per ton – Optimized power transmission and conditioning reduce specific energy consumption

4. Raw Material & Application Versatility

Processable materials:

  • Grains (corn, wheat, barley, sorghum)

  • Oilseed meals (soybean meal, rapeseed meal, cottonseed meal)

  • Fibrous materials (straw, hay, grass meal)

  • Animal by-products (meat & bone meal, feather meal, fish meal)

  • Aquatic ingredients (algae, aquatic plants)

Produced feed types:

  • Poultry feed (broiler, layer, breeder)

  • Livestock feed (pig, cattle, sheep, goat)

  • Aquafeed (fish, shrimp, crab)—floating or sinking pellets

  • Specialty feeds (pet food, horse feed, rabbit feed)

5. Built for 24/7 Production

The SYLH series is designed with industrial-grade components to support round-the-clock operation:

  • Heavy-duty gearbox – Precision-forged gears with splash lubrication handle continuous high-torque loads

  • Oversized main shaft – Reduced deflection means longer die and roller life

  • External bearing temperature monitoring – Optional sensors alert operators before overheating occurs

  • Automatic grease lubrication – Centralized system reduces manual maintenance intervals

Operational benefits:

  • 24-hour non-stop production capability

  • Consistent pellet quality across long runs

  • Predictable wear patterns—schedule maintenance, not emergency repairs

6. Installation, Training & After-Sales Support

Installation support:

  • Foundation drawings and site preparation guidance

  • On-site commissioning by experienced engineers

  • Remote technical assistance via video call for quick adjustments

Operator training (on-site or remote):

  • Daily startup, shutdown and cleaning procedures

  • Die and roller changeover techniques

  • Conditioner and steam system tuning

  • Troubleshooting common issues (overload, poor pellet quality, die blockage)

  • Safety protocols and lockout/tagout procedures

After-sales service:

  • 12-month warranty on the complete machine (excluding consumable wear parts)

  • Rapid response – Expert technical support team with defined escalation procedures

  • Spare parts availability – Critical components stocked for fast dispatch

  • Lifelong support – We stay with you for the life of the equipment, not just the warranty period

Our "5L" service commitment:

  • Listen to your needs

  • Locate the root cause

  • Layout a clear action plan

  • Launch the solution quickly

  • Long-term follow-up

7. Frequently Asked Questions

Q: How long can the equipment run continuously?
A: The SYLH series is designed for 24/7 continuous operation. The heavy-duty gear transmission and forced lubrication system maintain stable performance even under sustained full-load running.

Q: Does the equipment handle high-moisture or high-fiber materials?
A: Yes. The conditioner pre-treats fibrous or dry ingredients with steam and moisture, and the roller configuration can be selected (2, 3, or 4 rollers) to match material compressibility. For extreme cases, we offer customized conditioning and die specifications.

Q: How consistent is pellet quality across a long production run?
A: Very consistent. The variable-speed feeder maintains a uniform feed rate, and the gear-driven main shaft minimizes speed fluctuation under load. Regular die maintenance is the key factor—we provide clear guidelines for monitoring die wear.

Q: What support is provided during installation?
A: We supply detailed foundation drawings and installation manuals. For larger projects, we can dispatch field service engineers to oversee installation and commissioning. Remote video guidance is also available for quick troubleshooting.

Q: How do I choose the right model for my capacity needs?
A: Refer to the capacity table, but note that actual output depends on your specific formulation and moisture levels. We recommend contacting our technical team with your raw material details and target output—we can simulate expected performance and recommend the optimal model and die configuration.

Q: Can the equipment run on other Voltage?
A: Voltage and frequency can be customized .
