Introduction to double roller granulator:

1.In both blended and NPK fertilizer production lines, the Double Roller Granulator is a key piece of equipment.
2.Featuring advanced technology, compact structure and minimum energy consumption.
3.Ensures continuous and mechanized production with specific capacity by seamlessly integrating with complementary equipment to form a compact production line.
4.The double roll granulator uses a unique formulation that eliminates the need for drying and facilitates room temperature processing. The product meets the technical requirements of compound fertilizer due to the single rolling and forming process.
5.This plant is designed for the production of special compound fertilizers of high, medium and low concentration, tailor-made for different types of crops. It is a ground-breaking development in terms of energy efficiency in the complex fertilizer industry.

Below is a table of technical parameters of different models of double roller granulators, customers can choose the model according to the production output.

Working principle of double roller granulator:

• 1.The electric motor drives the belt and disc, transmitting power to the active shaft via the reduction gear.
• 2.Synchronised with the passive shaft by a set of open gears, the two roller skins work in opposite directions.
• 3.The material enters through the hopper where it gets extruded and shaped by the rollers, resulting in granulation.
• 4.The material then passes through a pair of chains to the crushing and screening area, where it is screened and separated to produce finished pellets.
• 5.The recycled material is then mixed with the new material for a further round of granulation.
• 6.As the motor continues to rotate, a steady flow of material is maintained, enabling seamless mass production.

Advantages of double roller granulator:

Produce efficiently:

The high speed rotation and the squeezing action of the rollers facilitate the rapid conversion of the raw materials in powder form into fertilizer granules without the need for additional water or steam. This efficiency results in a streamlined and resource-saving production process.

Flexibility and adjustability:

One of the key strengths of the double roll granulator is its ability to adapt to changing requirements. To suit different raw material characteristics and specific product requirements, the machine can be easily adjusted and controlled. Parameters such as roll speed, roll pitch and roll surface shape can be fine-tuned to allow the manufacturer to achieve the desired particle shape and size.

Broad range of applications:

The versatility of the Twin Roller Granulator extends well beyond the production of fertilizer. It is invaluable in the production of solid feed pellets, granular pesticides, herbal tablets and more. It is an indispensable tool in many industrial and agricultural sectors due to its flexibility and adjustability.

Improved granulation quality:

The superior formulation of the twin roll granulator eliminates the need for drying. This allows production at room temperature. Granules that meet the technical indicators required for compound fertilizer are produced by rolling and shaping the product once. This meets the industry’s demand for precise technical specifications as well as improving the overall quality of the end product.

Cost effective and energy efficient:

In the blended fertilizer industry, the Twin Roller Granulator represents a new generation of energy-saving and consumption-reducing technology. With the elimination of the drying step, the machine significantly reduces energy consumption, contributing to both cost savings and environmental sustainability.

Smooth operation:

The double roll granulator ensures stable and consistent operation with synchronized movements of the belt, pulley, active shaft and open gears. The material is efficiently processed as it passes through the feed hopper, is extruded and shaped by the rollers and finally screened in the crushing and screening room.
