The flat mold fertilizer granulator and the new fertilizer granulator each have their own unique features in the field of fertilizer production. Below is a detailed analysis of the differences between them.

In terms of working principle, the flat mold fertilizer granulator is driven by a motor to rotate the flat mold, and the pressure roller applies pressure to the material. The material is extruded through the mold holes on the flat mold under the action of centrifugal force and friction, and then cut into particles by a cutting blade. The new fertilizer granulator utilizes a high-speed rotating disc, where the raw materials are dispersed from the center to the edges under centrifugal force. At the same time, the nozzle sprays a binder to form particles under the combined action of centrifugal force and gravity.

In terms of particle characteristics, the particles produced by the flat die granulator are generally in the shape of columns and have a relatively uniform size. The length of the particles can be controlled by adjusting the cutting blade. This type of particle has good stability during storage and transportation. The particles produced by the new fertilizer granulator are nearly spherical, and spherical particles have better dispersibility in soil, which is conducive to the uniform release of fertilizer nutrients.

In terms of production efficiency, the production efficiency of the flat mold fertilizer granulator depends on the size and speed of the flat mold. Generally speaking, its processing capacity is relatively moderate and suitable for medium-sized production. The new fertilizer granulator, due to its high-speed rotation, can quickly process a large amount of raw materials, resulting in high production efficiency. However, the stability of the equipment and the continuity of raw material supply are also highly required.

In terms of raw material adaptability, the flat mold fertilizer granulator has certain requirements for the viscosity of the raw materials. Raw materials with moderate viscosity are easier to form through the mold holes. If the viscosity of the raw material is too high, it may cause blockage of the mold hole; If the viscosity is too low, it will be difficult to shape the particles. The new fertilizer granulator requires high flowability of raw materials, which need to be able to quickly disperse on a high-speed rotating disk, and have a strong dependence on binders.

There are also differences in energy consumption and maintenance costs of the equipment. The energy consumption of the flat mold fertilizer granulator is relatively low, and its structure is relatively simple. Maintenance mainly focuses on the wear inspection and replacement of the flat mold and pressure roller, and the maintenance cost is relatively low. The new fertilizer granulator has high energy consumption due to its high-speed rotation, and the maintenance of the equipment is also complex, requiring regular inspections of the wear of rotating components, resulting in relatively high maintenance costs.

From the perspective of equipment footprint, the flat mold fertilizer granulator has a relatively compact structure and occupies a small area. The new fertilizer granulator requires a large rotating space and supporting facilities, and occupies a large area.

There are significant differences between the flat mold fertilizer granulator and the new fertilizer granulator in terms of working principle, particle characteristics, production efficiency, raw material adaptability, energy consumption maintenance, and footprint. Fertilizer production enterprises should comprehensively consider these factors based on their actual situation and choose the most suitable granulation equipment to improve production efficiency and product quality.
