A Double Roller Extrusion Granulator is a highly efficient machine used in the production of organic and compound fertilizer pellets. This equipment operates through a dry granulation process, making it a popular choice for pelletizing materials like organic fertilizer, compound fertilizer, and other materials that are sensitive to moisture. The double roller extrusion granulator ensures high-quality, uniform pellets without requiring additional drying or cooling systems, which makes it both cost-effective and energy-efficient.

Working Principle

The double roller extrusion granulator works through the principle of dry extrusion granulation. The material is fed into the granulator through a hopper and then enters the compression zone between two counter-rotating rollers. As the rollers rotate, they compress the material, forming it into small, dense pellets. The pellets are then extruded through the granulator’s die holes, resulting in uniform-sized fertilizer granules.

Unlike traditional granulation methods that require wet processing, the roller press granulation process relies on the mechanical force exerted by the rollers to compact the material. This eliminates the need for binders or large amounts of water, making the process more environmentally friendly and reducing operational costs.

Key Features

1. Dry Granulation Process: One of the main advantages of using a double roller extrusion granulator is the dry granulation process. This allows for the production of high-density pellets without the need for drying, which saves energy and reduces the overall production time.
2. Efficient and Cost-Effective: The design of double roller pellet machine minimizes energy consumption while ensuring high throughput. Additionally, since it requires no binder, there are fewer raw materials and costs associated with pellet production.
3. Wide Applicability: The machine is suitable for making both organic and compound fertilizer pellets. It is capable of processing a variety of raw materials, including those that are hard to granulate using wet methods. Materials like ammonium bicarbonate, potassium sulfate, and organic compost can all be processed into high-quality fertilizer pellets.
4. Customization: The extrusion granulator is highly versatile. The size and shape of the pellets can be adjusted based on the die’s design and the operating conditions. This makes it suitable for meeting the specific needs of different fertilizer formulations.
5. Environmental Benefits: Since the granulation process is dry, it generates minimal waste and reduces the carbon footprint of the production process. There is no need for drying or cooling stages, further conserving energy and water.

Applications in Fertilizer Production

The double roller extrusion granulator is widely used in the production of both organic and compound fertilizers. It produces pellets with a uniform size and excellent strength, making them ideal for agricultural use. These pellets release nutrients slowly, ensuring a steady supply to plants over an extended period. The granulator’s ability to handle a variety of raw materials also makes it a flexible option for producing fertilizers tailored to specific crops or soil conditions.
