Product Description

Product Description

Overview of Ring Die Granulator

The Gofine Ring Die Granulator is a high-performance system engineered for producing organic fertilizers, bio-fertilizers, compound fertilizers, animal feed, and other granular products. Designed for stable, continuous operation, it processes a wide range of raw materials—including chicken manure, compost, crop straw, wheat, corn, millet, diatomaceous earth, forage, and agricultural wastes. Finished granules are adjustable from 2 mm to 8 mm in diameter, offering flexibility to meet diverse market demands.

Features of Ring Die Granulator

• Single or Double-Layer Conditioner — Selected based on material characteristics to dry and mature the material using steam.

• Uniform Feeder — Ensures a stable material flow rate, facilitating the smooth operation of the granulation process.

• Smooth, Dense Pellets — Produces high-quality pellets with a glossy surface, high structural strength, and minimal dust.

Application of Ring Die Granulator

Gofine ring-die pellet mills are widely utilized across various industries:
Bio-organic Fertilizer Production: Converting composted livestock and poultry manure (chicken, cattle, and pig manure), crop residues, landscaping waste, and spent mushroom substrate into pellets.
Compound Fertilizer (NPK) Granulation: Forming mixed powdered formulations into cylindrical pellets.
Animal Feed Industry: Processing grains (corn, wheat, millet, soybean meal) into pellets for the production of livestock, poultry, and aquaculture feeds.
Soil Amendments: Granulating diatomaceous earth, zeolite, bentonite, or mineral mixtures.
Biomass Fuel Production: Processing wood chips, sawdust, crop stalks, and rice husks into biomass fuel pellets.

How to Produce High-Quality Organic Fertilizer Granules?

Step 1: Raw Material Pre-treatment — Dewatering or Coarse Crushing
Dewater high-moisture raw materials (such as fresh chicken manure) or crush large-sized materials to ensure uniform particle size.

Step 2: Drying
Utilize a rotary dryer to control moisture content, thereby preventing nutrient loss and minimizing dust generation.

Step 3: Fine Grinding
Grind the raw materials to an optimal fineness to ensure a smooth and efficient granulation process.

Step 4: Precise Feeding
Employ an automatic batching system to precisely proportion the raw materials, ensuring a balanced nutrient composition.

Step 5: Intensive Mixing
Thoroughly mix the raw materials to ensure that all components are uniformly distributed.

Step 6: Ring Die Granulation
Through a high-pressure extrusion process, force the raw materials through die holes to form cylindrical granules (2–8 mm in diameter).

Step 7: Polishing and Shaping
Remove surface burrs from the granules to render them smooth and lustrous, thereby enhancing the product's aesthetic quality.

Step 8: Cooling and Drying
Reduce the temperature and moisture content of the granules to increase their hardness and facilitate storage.

Step 9: Automated Packaging
Screen the granules; qualified granules are automatically bagged, while fine fragments and undersized particles are recycled for re-granulation.
