Double Roller Press Granulator occupies an important position in the fertilizer manufacturing industry. It is a granulation equipment with a wide adaptability to raw materials, small investment and can bring great economic benefits.

The working process of the Double Roller Press Granulator is divided into two stages: extrusion and granulation.

1.Extrusion stage

Adding materials: Add dry materials from the feed hopper and enter between two counter-rotating rollers.

Roller drive: The rollers are driven by an electric motor through a transmission device, and the two rollers work synchronously and in opposite directions.

Extrusion effect: The air between the material particles is squeezed out, so that the dry material is compressed into a hard and dense block under the action of pressure.

2.Granulation stage

Crushing: The material pressed into blocks is broken into countless small particles under the crushing action of the Double Roller Press Granulator.

Screening: The crushed material is screened, and the finished particles flow out of the machine through the screen to the discharge trough, while the particles that do not meet the finished product specifications are returned and mixed with new materials for granulation.

The Double Roller Press Granulator has the following features:

1.Precision granulation

The Double Roller Press Granulator can accurately shape fertilizer particles. It uses the roller extrusion principle to ensure that the particles are regular in shape and uniform in size. Regular particles have great advantages in the packing, storage and transportation of fertilizers. They are not prone to breakage, agglomeration and other problems, ensuring the stability of fertilizer quality.

2.Reduce fertilizer costs

It can efficiently utilize fertilizer raw materials and reduce fertilizer loss and volatilization. In the process of extrusion granulation, almost all raw materials can be converted into usable fertilizer particles, and other substances can be added to increase the nutritional content, thereby reducing fertilizer costs.

3.Long service life

The main components of our Double Roller Press Granulator are made of new metals that are corrosion-resistant, wear-resistant and impact-resistant. The bearing frame also uses high-quality anti-corrosion castings, and the frame has also been upgraded, which greatly improves its service life.

In short, the Double Roller Press Granulator is an ideal choice for fertilizer production enterprises to achieve efficient, high-quality and environmentally friendly production, and is an important equipment to promote the development of the fertilizer industry.
