1. Overview
In the era of intensive livestock and poultry breeding, the demand for high-quality, large-batch animal feed pellets has grown exponentially. The Industrial Ring Die Feed Pellet Mill stands as a cornerstone of modern feed processing, leveraging mature technology to produce premium pellets for chickens, cattle, horses, ducks, and other livestock.
Renowned for its high throughput, low energy consumption, and reliable performance, this machine has secured a leading position in both domestic and international markets. It is the ideal choice for large-scale operations—including commercial feed factories, intensive livestock farms, and professional feed processing facilities—enabling efficient, standardized production of nutritious animal feed.
2. Product Introduction
The Industrial Ring Die Feed Pellet Mill is engineered exclusively for large-scale industrial production, with capacities ranging from 1.5T/H to 20T/H. It transforms accessible raw materials (corn, wheat bran, rice, soybeans, agricultural by-products, etc.) into uniform, dense pellets with smooth surfaces—enhancing feed palatability, reducing waste, and improving nutrient absorption in animals.
Unlike small-scale equipment, this mill integrates advanced transmission and conditioning technologies to meet the rigorous demands of continuous, high-volume production, making it a critical asset for scaling feed operations.
3. Main Structure
The AMS Industrial Ring Die Feed Pellet Mill features a modular, precision-engineered structure, comprising key components that work in synergy to ensure efficient production:
- Feeding Device: Controlled by a frequency conversion motor to regulate material supply, ensuring consistent pelleting and avoiding overloads.
- Conditioning System: Includes optional extra-large or jacketed conditioners to fully temper raw materials with steam, enhancing pellet binding and nutritional retention.
- Press Chamber & Transmission System: Houses the ring die and pressure rollers, driven by a high-precision gear system for stable power transfer.
- Overload Protection: Automatically shuts down the machine during jams or excessive load to protect core components.
- Electrical Control System: Centralized panel for easy operation, monitoring, and adjustment of production parameters.
4. Core Advantages
4.1 Mature Technology & High Efficiency
Built on proven engineering, the mill delivers 20% higher productivity compared to belt-driven models, thanks to its high-precision gear transmission system. This reduces energy consumption while maintaining consistent output—critical for large-scale operations aiming to lower per-unit costs.
4.2 Stable & Reliable Performance
Equipped with imported SKF bearings and NAK oil seals, the transmission system operates smoothly with minimal noise (≤90dB(A)). The international advanced compensation-type spring coupling ensures a compact, safe structure with low failure rates, supporting continuous 24/7 production.
4.3 Customizable for Versatility
- Multiple Ring Die Apertures: Choose from 2mm to 10mm die holes to produce pellets tailored to different animals (e.g., 2mm for chicks, 8-10mm for cattle).
- Flexible Conditioning Options: Extra-large or jacketed conditioners can be added to meet specific tempering needs, improving pellet hardness and stability.
4.4 Superior Pellet Quality
The precision-machined ring die (with long service life) ensures pellets have a shaping rate of ≥95%—uniform in size, dense, and resistant to crumbling. This reduces feed waste during transportation and feeding.
4.5 Ideal for Large-Scale Production
Compared to flat die pellet mills, this ring die model excels in high-volume scenarios, with capacities up to 20T/H—making it indispensable for commercial feed factories and large livestock operations.
5. Suitable Raw Materials
The mill processes a wide range of agricultural materials and by-products, including:
- Grains: Corn, wheat, rice, barley
- Oilseed meals: Soybean meal, rapeseed meal
- By-products: Wheat bran, rice husk, straw powder, agricultural leftovers
- Additives: Vitamins, minerals, probiotics (mixed with base materials for balanced nutrition)
6. Usage Tips & Maintenance Guidelines
To maximize efficiency and extend equipment lifespan, follow these best practices:
- Pre-Purchase Planning: Consider production demand, raw material types, and budget to select the right model (e.g., SZLH508 for 4-20T/H capacity).
- Proper Operation: Train staff to use the electrical control system correctly, avoiding manual adjustments during operation.
- Regular Maintenance:
- Inspect wear parts (ring die, pressure rollers) weekly; replace when worn to maintain pellet quality.
- Change gearbox lubricating oil per the manual to reduce friction.
- Clean the conditioner and press chamber daily to prevent residual material buildup.
- Avoid Overloading: Adhere to rated capacity to prevent motor or gear damage. Use the overload protection system as a safety net.
