Ring Die Pelletizer Production Line
- Information
Product Overview
The Gofine Ring Die Pellet Production Line is a comprehensive, fully integrated granulation system designed for the efficient production of high-quality organic fertilizer, bio-fertilizer, compound fertilizer (NPK), and animal feed pellets. Engineered for continuous operation, this production line combines advanced crushing, mixing, conditioning, granulation, polishing, cooling, screening, and packaging equipment into a seamless workflow.
At the core of the system is a high-precision ring die pellet mill. It has a steam conditioning function, resulting in particles that are smooth and compact in shape.
With adjustable pellet diameters from 2mm to 8mm and customizable configurations, the line offers the flexibility to process a wide range of raw materials—including chicken manure, compost, crop straw, wheat, corn, millet, diatomaceous earth, and various agricultural residues—into market-ready fertilizer or feed granular products.
Features of Ring Die Granulator
Flexible Conditioning System
Single or double-layer stainless steel conditioner with steam injection (80–90°C) thoroughly mixes and gelatinizes materials, improving binding properties and pellet durability.
Uniform Feeding with VFD
Variable frequency drive-controlled feeder ensures consistent material flow, stabilizing the granulation process and producing uniform pellet quality batch after batch.
Adjustable Pellet Size
Quick-change ring dies available from 2mm to 8mm; adjustable cutters control pellet length for full product specification flexibility.
Superior Pellet Quality
Produces smooth, glossy, high-density pellets with excellent mechanical strength (>95% durability), minimal dust, and attractive appearance for higher market value.
Application of Ring Die Granulator
Manure: chicken, cow, pig, horse
Crop residues: wheat straw, corn stover, rice straw, grass
Agricultural byproducts: peanut shells, sunflower husks, coffee grounds
Minerals: diatomaceous earth, Seaweed slurry, bentonite
Compost: municipal organic waste, mushroom residue, garden waste

Ring Die Granulation Production Line Process
| Process Stage | Equipment | Technology | |
| 1 | Raw Material Pre-treatment | Dehydrator / Crusher | Reduce moisture (if >40%); crush large lumps to uniform size |
| 2 | Drying | Rotary Dryer | Control moisture to 15–20%; adjust temperature to prevent nutrient loss |
| 3 | Fine Grinding | Vertical Crusher / Hammer Mill / Raymond Mill | Grind to fine powder for optimal granulation |
| 4 | Accurate Feeding | Automatic Batching System | Precisely weigh and proportion raw materials (organic matter, NPK, binders) |
| 5 | Intensive Mixing | Ribbon Mixer / Double Shaft Paddle Mixer | Blend thoroughly with steam or water to achieve 20–25% moisture |
| 6 | Conditioning | Stainless Steel Conditioner (Single/Double) | Steam-heat to 80–90°C; activate starches and natural binders |
| 7 | Granulation | Ring Die Pellet Mill | High-pressure extrusion forms cylindrical pellets (2–8mm diameter) |
| 8 | Polishing (Optional) | Polishing Machine | Smooth pellet surfaces; remove burrs for glossy appearance |
| 9 | Cooling | Counter-Flow Cooler / Rotary Cooler | Reduce temperature and moisture; harden pellets for storage |
| 10 | Screening | Vibrating Screen | Classify pellets; on-spec product to packaging, fines return to Step 4 |
| 11 | Packaging | Automatic Packing Machine | Weigh and bag finished pellets for sale |
