In the field of environmental protection granulation, wet granulation and dry granulation as two mainstream technologies, each has its own advantages, choosing the appropriate process is crucial to improve product quality, reduce energy consumption and meet environmental requirements. The choice of environmentally friendly granulation process should be based on comprehensive considerations, both to meet production needs, but also to take into account environmental benefits. Whether it is the wet granulator of the Disc Granulator, or the dry granulator of the Roller Press Granulator and the organic fertilizer Double die pelleting machine, it has its unique advantages and application scenarios. Through scientific comparison and reasonable selection, we can contribute more green power to the environmental protection pelletizing industry.

Disc Granulator: the model of wet granulation



With its unique rotating disk design, the Disc Granulator evenly sprays the binder on the material through the spray system, and uses the centrifugal force of the disc to promote the material agglomeration into pellets. In this process, the adhesion between wet materials is enhanced, and it is easy to form regular and dense particles, which is especially suitable for handling materials with large viscosity. However, wet granulation needs to be dried, which increases energy consumption and cost.

Roller Press Granulator : the elite of dry granulator



In contrast to the wet granulation process, the Roller Press Granulator does not need to add a lot of water, and the material is extruded by two relatively rotating rollers. This method has the advantages of low energy consumption, high efficiency, high particle strength and uniform particle size, and is especially suitable for handling dry and fragile materials. There is no need for additional drying in the dry granulation process, which reduces environmental pollution and energy consumption, and conforms to the modern environmental protection concept.

Organic fertilizer Double die pelleting machine: an innovative choice for dry granulator



As an innovative application of dry granulation technology, the organic fertilizer Double die pelleting machine adopts double mold design to form two rows of particles at one time, which greatly improves the production efficiency. Its unique granulation mechanism makes the material compressed and formed under high pressure, the particles are strong and the appearance is smooth, especially suitable for the production of organic fertilizer and other granular fertilizers. The dual-mode design also reduces mold wear, prolongs the service life of the equipment, and further reduces production costs.

Comparison and selection

When choosing wet or dry grain, it is necessary to consider the characteristics of raw materials, product requirements, production costs and environmental protection needs. Wet granulation is suitable for materials with large viscosity and not easy to form, but it is necessary to pay attention to the energy consumption and pollution in the drying process. The dry granulation has the advantages of high efficiency, energy saving and environmental protection, which is excellent in the treatment of dry and fragile materials. For specific fields such as organic fertilizer, the organic fertilizer Double die pelleting machine has become an ideal choice for dry granulator with its unique innovative design.
