Extrusion Granulator: Efficient and Eco-Friendly Solution for Fertilizer and Feed Production

Extrusion granulator is a widely used piece of equipment in fertilizer production that forms powder or fine granular materials into specific shapes and sizes through mechanical extrusion. This process is commonly applied in the production of compound fertilizers, granular fertilizers, feed, and other pelletized products. It is known for being efficient, environmentally friendly, and energy-saving. Below is a detailed explanation of the extrusion granulator.

Working Principle of Extrusion Granulator:

The core principle of the extrusion granulator is to physically compress materials under high pressure, typically through screws or roller pressing, transforming them into solid granules. The process does not require liquid binders and relies solely on the physical properties of the materials to form granules. The steps are as follows:

Material Feeding: Powder or small granular materials are fed evenly into the granulator through the feeding system.

Extrusion Process: Inside the granulation chamber, the material is pressed by two rotating rollers or screws, causing plastic deformation.

Granule Formation: Under pressure, the material is compressed into granules of a specified shape and size.

Granule Discharge: The formed granules are discharged through an outlet, then screened and cooled to produce the final granulated product.

Advantages of Extrusion Granulators:

Environmentally Friendly and Energy-Efficient: The extrusion process does not require heating or drying, saving significant amounts of energy.

High Production Efficiency: Granulation speed is fast, with high output, making it suitable for large-scale production.

No Chemical Binders: Granules are formed through physical compression without the need for binders, maintaining product purity.

Flexible Product Shapes: By changing the mold, the extrusion granulator can produce granules of different shapes and sizes, catering to varying market demands.

Extrusion Granulator Application Areas:

Compound Fertilizer Production: Extrusion granulators are widely used for producing NPK compound fertilizers, especially for low- and medium-concentration fertilizers.

Organic Fertilizer Production: Suitable for processing organic materials such as animal manure and straw into organic fertilizer granules.

Feed Processing: Can be used to make pelletized feed for livestock, poultry, and fish, improving feed’s physical properties and storability.

Other Industrial Applications: The extrusion granulation process is also used in industries such as chemicals and pharmaceuticals to produce granular products.

Common Types of Extrusion Granulators:

Double-Roller Extrusion Granulator: Forms granules by compressing material through two rotating rollers, suitable for producing compound fertilizers, potash fertilizers, and more.

Screw Extrusion Granulator: Uses rotating screws to push material toward the outlet to form granules, widely used in feed, plastics, and other industries.

Equipment Maintenance:

Regularly inspect extrusion components for wear and replace damaged parts in time.

Ensure proper lubrication of the equipment to avoid prolonged operation under dry friction.

Clean residual material to prevent clogging, which can reduce production efficiency.

How to selcet the right Extrusion Granulator for your production?

Here are the top 5 Request for Quotation (RFQ) items typically included when inquiring about an Extrusion Granulator:

1. Production Capacity

Specify the desired output (e.g., tons per hour or per day) to ensure the granulator meets your production needs.

2. Material Type and Characteristics

Provide details about the materials you intend to process (e.g., NPK compound, organic fertilizer, feed), including particle size, moisture content, and any special characteristics.

3. Granule Size and Shape

Indicate the preferred granule size and shape (e.g., diameter, cylindrical, spherical) to ensure the machine can deliver the desired product.

4. Power Requirements and Energy Consumption

Request details about the machine’s power specifications (e.g., voltage, power consumption), especially for ensuring compatibility with your facility’s infrastructure.

5. Customization Options and Additional Features

Ask about available customization options, such as mold changes for different granule shapes, or additional features like automatic feeding, cooling, and screening systems.

These RFQs will help you gather essential technical specifications and pricing to make an informed decision.

Due to its high efficiency, environmental benefits, and adaptability, the extrusion granulator has become an essential piece of equipment in industries such as fertilizer and feed production.
