Organic fertilizer granulator

I. Product Overview

The organic fertilizer granulator machine is a specialized equipment designed to process powdered or small granular organic materials into granulated organic fertilizer. It is widely used in the production of organic fertilizers, bio-fertilizers, compound fertilizers, agricultural waste treatment, and the resource utilization of livestock manure. Through the granulation process, organic fertilizer particles are uniform in shape, moderately hard, nutritionally stable, and convenient for storage and transportation, thereby enhancing the market competitiveness of organic fertilizer products.

There are various types of organic fertilizer granulators, including disc granulators, rotary drum granulators, double roller extrusion granulators, stirring tooth granulators, flat die granulators, and ring die granulators. Each type is suitable for different materials and process requirements.

The organic fertilizer granulator features a high granulation rate, uniform particles, low energy consumption, and stable operation.

II. Working Principle

The working principle of an organic fertilizer granulator mainly involves mechanical extrusion, rotary rolling, wet adhesion, or dry molding to convert powdered or small granular materials into uniform granules. Different types of granulators have slight variations in their working mechanisms, as outlined below:

(1) Disc Granulator (Wet Granulation)

• The material is added into a rotating disc, where it gradually rolls into spherical granules under the influence of the disc’s tilt angle and centrifugal force.
• A spraying system applies an appropriate amount of water to enhance particle adhesion and gradually increase granule diameter.
• The formed granules are discharged through the outlet and proceed to the drying and cooling stages.

(2) Rotary Drum Granulator (Wet Granulation)

• The material enters a rotating drum via a conveyor belt, where internal lifting devices help the material tumble along the drum wall.
• Spraying water or adhesive promotes particle aggregation into spherical granules.
• The drum is slightly inclined, allowing the granules to move towards the discharge end gradually.

(3) Double Roller Extrusion Granulator (Dry Granulation)

• The material passes through two high-pressure rollers, where it is compressed into sheet form.
• The sheets are then crushed and screened to obtain uniform granules, eliminating the need for drying.
• This method is suitable for low-moisture materials and has low energy consumption.

(4) Stirring Tooth Granulator (High-Moisture Granulation)

• High-speed rotating stirring teeth use shear force, collision, and friction to agglomerate materials into spherical granules.
• Suitable for high-moisture organic materials such as livestock manure, sludge, and sugar residue, eliminating the need for drying before granulation.

Each process is designed for different materials, allowing users to choose the most suitable granulation equipment based on production needs.

III. Product Applications

(1) Organic Fertilizer Production

• Suitable for processing livestock manure (chicken, cow, pig, sheep manure), straw powder, crop residues, bark, sawdust, and other biomass materials.
• The granulated organic fertilizer has uniform particles and stable nutrients, suitable for various crops.

(2) Agricultural Waste Recycling

• Effectively processes agricultural by-products such as sugar residue, distiller’s grains, mushroom residue, cassava residue, and cottonseed hulls, improving resource utilization and reducing pollution.

(3) Soil Conditioner Production

• Produces granular organic fertilizers that improve soil water retention, aeration, and organic matter content, promoting crop growth.

(4) Compound Fertilizer Production

• Suitable for organic-inorganic compound fertilizer production, improving fertilizer efficiency and reducing chemical fertilizer loss.

The organic fertilizer granulator machine is widely used in organic fertilizer production enterprises, agricultural cooperatives, livestock farms, and ecological agriculture parks.

IV. Product Features

(1) High Granulation Efficiency & Yield

• The granulation rate reaches over 90%, producing uniform particles with minimal powder recycling.

(2) Wide Applicability & Strong Compatibility

• Capable of processing high-moisture materials (30%-50% moisture content), low-moisture powder materials, and compound materials.

(3) Low Energy Consumption & Stable Operation

• Reasonable structural design ensures low power consumption and cost-effective large-scale production.

(4) High-Quality Granules Meeting Agricultural Standards

• The granules are uniform, moderately hard, and resistant to breakage, making them easy to store and transport.
• Slow nutrient release improves fertilizer utilization efficiency.

(5) Environmentally Friendly with Minimal Dust Emission

• Enclosed granulation design reduces dust pollution and meets environmental protection standards.
• Optional dust collection systems improve working conditions and comply with environmental regulations.

(6) Durable Equipment with Easy Maintenance

• Key components are made of wear-resistant alloy, stainless steel, or carbon steel for long service life.
• The well-designed structure allows easy disassembly and maintenance, reducing maintenance costs.

V. Technical Parameters

Note: Specific parameters can be customized based on requirements.

VI. Purchasing Recommendations

When selecting an organic fertilizer granulator, consider the following key factors:

• Production Capacity: Choose the appropriate machine model to avoid inefficiencies due to undersized or oversized equipment.
• Granulation Method: Select the right granulator based on material moisture content (wet granulation, dry granulation, or high-moisture granulation).
• Material Selection: Prefer equipment made from wear-resistant alloy or stainless steel for extended durability.
• Power Configuration: Opt for high-efficiency and energy-saving motors to reduce operating costs.
• After-Sales Service: Choose manufacturers that offer installation, debugging, maintenance, and spare parts supply.

The organic fertilizer granulator machine is a core piece of equipment in the organic fertilizer, bio-fertilizer, and compound fertilizer industries. It enhances fertilizer quality and market competitiveness. Selecting the right granulator model improves production efficiency, reduces energy consumption, and optimizes product quality, meeting the sustainable development needs of modern agriculture.
