Overview of Rotary Drum Granulator Machine

The rotary drum granulator (also known as a rotary granulator) is a core forming equipment developed based on wet granulation technology. It is widely used in the large-scale production of organic fertilizers, compound fertilizers, and other fields. The equipment uses a rotating inclined drum, combined with precise humidity control and material rolling and agglomeration, to process powdery raw materials (such as livestock manure, ammonium phosphate powder, straw powder, etc.) into granules with uniform particle size and meeting strength standards. It is suitable for cold and hot granulation processes and the production of high, medium, and low concentration compound fertilizers.

Features of Rotary Drum Granulator Machine

1. Highly efficient granulation with strong stability:

≥90% pelletizing rate, controllable particle size of 2–5mm, round and uniform particles, minimal material return.

2. Low energy consumption and easy maintenance:

Motor + reducer drive reduces energy consumption by 15%–20%; wear-resistant and corrosion-resistant lining, automatic descaling, long service life.

3. High adaptability and flexible processes:

Supports water, steam, and binder humidification; compatible with both hot and cold granulation methods; suitable for various raw materials.

4. Simple operation and high degree of automation:

Compact structure, stable operation, can be equipped with online moisture monitoring and automatic spraying, suitable for continuous production lines.

Working Process of Rotary Drum Granulator Machine

The drum granulator adopts the wet granulation method, through a certain proportion of water or steam, after the material reaches a certain humidity in the cylinder, a corresponding chemical reaction occurs. With the help of the rotating motion of the barrel, the material is agglomerated into spherical granules by using the principle of continuous mosaic growth between molecules.

Gofine granulators can be used for the production of granules for organic fertilizers, NPK, Urea, cat litter, and fragrance beads.

How to Produce High-Quality Fertilizer Granules?

Application of Rotary Drum Granulators in Production Lines

1. Raw Material Pretreatment: Nitrogen, phosphorus, potassium, organic fertilizer, sludge, and other powders are uniformly mixed, and the moisture content is controlled.

2. Quantitative Feeding into the Granulator: The powder continuously enters the rotary drum, where it is atomized and sprayed with water/steam/binder to form core granules.

3. Rolling Granulation and Shaping: The granules continuously grow and become rounded within the drum, resulting in uniform particle size and high strength.

4. Granule Grading and Screening: Qualified granules are dried and cooled, while unqualified granules are recycled.

5. Finished Product Packaging: After coating and anti-caking treatment, the finished product is directly packaged as high-quality fertilizer.
