The rotary drum granulator, with its unique rolling granulation method, has demonstrated high efficiency in the field of organic fertilizer production.
After the mixed organic fertilizer materials enter the rotary drum granulator, a wonderful granulation journey begins as the drum rotates at a constant speed. The materials constantly roll and collide inside the drum, like a lively gathering in a huge ‘drum’. In this process, the moisture in the material acts as an important “adhesive”, promoting the gradual aggregation and growth of particles.
To accelerate the granulation speed, operators can spray an appropriate amount of adhesive solution into the drum to further enhance the viscosity between materials. The adhesive solution evenly covers the surface of the material, making it easier for the originally loose material to aggregate together and accelerating the formation of particles.
The granulation method of the rotary drum granulator determines its extremely high production efficiency. The continuous rotation of the drum enables the granulation process to proceed uninterrupted and can process a large amount of material per hour. This is crucial for large-scale organic fertilizer production enterprises to meet the growing market demand for organic fertilizers and enhance their market competitiveness.
This granulation method has a wide range of adaptability to raw materials. Whether it is various organic materials such as animal manure, crop straw, kitchen waste, or mixed raw materials containing a certain proportion of inorganic components, the rotary drum granulator can include them in the “granulation plan”. It can flexibly control the size and strength of organic fertilizer particles by adjusting parameters such as drum speed, material filling rate, and binder spraying amount based on the characteristics of different raw materials. For example, appropriately reducing the rotational speed of the drum can prolong the residence time of materials in the drum, which is beneficial for the formation of larger particles; Increasing the spraying amount of adhesive can improve the strength of particles.
The rotary drum granulator, with its efficient rolling granulation method, wide adaptability to raw materials, and flexible parameter control ability, has become an indispensable and important equipment on the organic fertilizer production line, playing an important role in promoting the large-scale development of the organic fertilizer industry.
