RICHI Pellet Machine, a professional manufacturer of agricultural and industrial granulation equipment, has won wide recognition in the global market with its advanced fertilizer granulator solutions. This article will comprehensively interpret the fertilizer granulator machine, focusing on its main types, working principles, core advantages, multi-field applications and scientific purchasing strategies, to provide practical guidance for fertilizer manufacturers, agricultural cooperatives and investors.

Main Types of Fertilizer Granulator Machine & Their Core Working Principles

Different types of fertilizer granulator machines are designed for different raw material characteristics, production scales and product requirements. RICHI provides a complete series of fertilizer granulator equipment, covering the main types required for organic and compound fertilizer production. The core types and their working principles are as follows:

1. Double Roller Extrusion Granulator: This type adopts dry granulation technology without adding water or binders, realizing normal temperature molding. The core working principle is that two sets of relatively rotating pressure rollers apply high pressure to the powdery material, making the material undergo plastic deformation and bond into particles. The whole process includes feeding, high-pressure extrusion, cake breaking and screening. The finished particles are mostly cylindrical or oblate, with high hardness and good stability. RICHI double roller extrusion granulator is equipped with an intelligent hydraulic pressure control system, which can accurately adjust the pressure according to the material characteristics, ensuring the granulation rate and particle quality.
2. Rotary Drum Granulator: It is a typical wet granulation equipment, suitable for large-scale production of high, medium and low concentration compound fertilizers. The working principle is that the drum rotates to make the material in a fluidized state. At the same time, the spraying system sprays an appropriate amount of water or steam to humidify the material. Under the combined action of extrusion, collision and friction between materials, the particles gradually agglomerate and grow into granules. RICHI rotary drum granulator adopts counterflow design and rubber engineering plastic lining, which improves heat transfer efficiency, prevents material adhesion, and has the advantages of high output, low energy consumption and long service life.
3. Disc Granulator: Relying on the combined effect of centrifugal force, friction and gravity, the tilted disc rotates to roll the material inside the disc. At the same time, spraying adhesive promotes the aggregation and growth of material particles, and finally forms circular particles that roll down from the edge of the disc. This type of equipment has the advantages of simple operation, good particle roundness and strong adaptability, and is suitable for small and medium-sized production of organic fertilizer and special compound fertilizer. RICHI disc granulator can adjust the disc inclination and rotation speed through frequency conversion, flexibly controlling the particle size and production efficiency.
4. Flat Die Granulator: It uses mechanical extrusion for granulation, conveying the pretreated material between the flat die and the pressure wheel. The pressure wheel applies pressure to the material to force it through the die holes on the flat die to form columnar particles, which are then cut into fixed-length particles by a cutter. This equipment does not need high-temperature drying, which can maximize the retention of active ingredients in heat-sensitive materials. It is suitable for small-batch production of organic fertilizer, bio-organic fertilizer and slow-release fertilizer. RICHI flat die granulator has a compact structure and low energy consumption, and is an ideal choice for small workshops and experimental lines.
