In the world of fertilizer production, the double roller granulator stands out as an innovative solution for manufacturing high-quality organic compound fertilizer granules. This advanced granulation equipment has revolutionized how we process organic materials into valuable fertilizers, offering numerous advantages over traditional methods.

What is a Double Roller Granulator?

A double roller granulator, also known as a dry granulation machine, is a specialized piece of fertilizer manufacturing equipment that transforms powdered materials into uniform granules through mechanical compression. Unlike wet granulation methods, this process requires no liquid additives or drying procedures, making it both economical and environmentally friendly.

• Key Features and Advantages

The roller granulator boasts several remarkable features that make it ideal for organic compound fertilizer production:

Dry Process Technology: As a dry granulator, it eliminates the need for moisture addition and subsequent drying, significantly reducing energy consumption.

High Compression Strength: The machine produces dense, durable granules that maintain their integrity during handling, storage, and transportation.

Versatile Material Compatibility: It effectively processes various organic materials including: Animal manure, Agricultural waste, Food processing byproducts, Green waste, Other organic compounds

Environmentally Friendly Operation: The closed-system design minimizes dust emissions and material loss, contributing to a cleaner production environment.

Low Operating Costs: With minimal moving parts and no requirement for drying facilities, maintenance and operational expenses are significantly reduced.

• Working Principle

The double roller press granulator operates on a straightforward yet effective principle. Raw materials in powder form are fed between two counter-rotating rollers. Under high pressure, the materials are compacted into a thin sheet, which is then broken into uniform granules through a crushing and screening process. This mechanical process ensures consistent granule size and quality.

Applications in Organic Fertilizer Production

The organic fertilizer granulator finds extensive applications in various aspects of fertilizer manufacturing:

• Organic Compound Fertilizer Production: Perfect for creating balanced nutrient formulations by combining multiple organic materials.

• Specialty Fertilizer Manufacturing: Suitable for producing customized fertilizer blends tailored to specific crop requirements.

• Waste Recycling: Effectively converts organic waste materials into valuable fertilizer products.

• Bio-fertilizer Production: Maintains the viability of beneficial microorganisms through its gentle compression process.

Technical Specifications

Modern roller granulators come with various technical features:

• Capacity ranges from 1-20 tons per hour

• Adjustable roller pressure for different material requirements

• Customizable granule sizes from 2-12mm

• Robust construction with wear-resistant materials

• Automated control systems for consistent operation
