Work Principle of Double Roller Granulator 

Structure of Double Roller Extrusion Granulator

Double roller press granulator make granules through the process of extrusion and pelletizing. Besides, the extrusion process is the dry material under pressure agglomeration into dense hard chunk materials. And the pelletizing process make fertilizer granules by demoulding after the roller extrusion granulation.

Why We Suggest Choose Double Roller Extrusion Granulator?

The extrusion granulation produce at the room temperature without drying, requiring no fuel, gas or other drying steps when compared to other methods.

Dry granulation requires only the application of the material’s inter-molecular forces, simplifying the process and reducing energy consumption.

Due to the elimination of the drying process, no return material, one-step forming, and low noise, the system is simple to operate and maintain so that you can reduce more investment costs.

Extrusion granulation production with a wide range of raw materials, can produce a variety of concentrations and types of compound fertilizer. Additionally, the use of extrusion granulation is flexible in a very short period of time to achieve product formulation replacement, and a set of devices can apply several product formulations.

The driving force of double roller extrusion granulator is electricity, with no three waste emissions, in accordance with the enterprise’s environmental protection growth policy.

The main parts such as the frame is made of new metal that is resistant to corrosion and wear. Moreover, its bearing frame body is made of excellent quality and anti-corrosion materials with good stability, extending the service life of rolling bearings.
