rotary drum granulator machine making compound fertilizer

Rotary drum granulator belongs to one of the key fertilizer granulation equipment for compound fertilizer granules. It is suitable for cold and hot granulation for high, medium and large scale production. This compound fertilizer granulator can manufacture low and high concentration compound fertilizer granules. The internal finish of the rotary drum granulator is made of special polyethylene resistant rubber sheet. This rotary granulator has the advantages of high granulation rate of compound fertilizer, beautiful appearance, corrosion resistance, low energy consumption, easy operation and maintenance, etc.

In addition to this drum granulator, our multifunctional double roller granulator can also produce compound fertilizer. High efficiency fertilizer granulator is considered to be the most important equipment in large-scale compound fertilizer production. By adding a certain amount of steam and vapor, the raw material in the rotary drum granulation machine becomes homogeneous and moist during the granulation process. Then a series of chemical reactions will take place. In this rotary granulating machine, the fertilizer granules are pressed against each other and rolled into fertilizer pellets. Uniform fertilizer granules of up to 3-8 mm are formed. With the continuous addition of raw materials and the rotation of the drum, large-scale production and work efficiency are ensured.

Rotary Drum Granulator

Working Principle of rotary Granulator

The main working mode of rotary granulator is aggregate wet granulation. The base fertilizer is wet mixed inside the drum granulator tube after a certain amount of water or steam has been fully chemically reacted. Under certain liquid conditions, with the rotary motion of the rotary drum, the material particles produce extrusion stress and re-agglomerate into balls.

Features of rotary Granulator

1. High granulation rate of rotary granulation machine, about 70% or more, unqualified granules can be re-granulated.
2. hot steam to improve the material moisture, so that compound fertilizer granulation easy
3. compound fertilizer granulator inner layer of polyethylene, so that raw materials are not easy to stick to the machine, anti-corrosion and heat preservation.

Why Our Drum  Granulator

1.The inner drum is fixed with polyethylene plastic sheet to prevent sticking and protect the drum from corrosion.

2. The drum is placed at an angle in a support made of strong carbon steel plates and channels.

3. The drum wall of the drum pelletizer is equipped with a shovel plate, which is convenient for pelletizing and cleaning.

4. The drum is machined by our vertical lathe, which is strong and suitable for pelletizing.

5. Reasonable design. The motor drives the gear, and the gear drives the drum.

6. Energy-saving, smooth granulation process, low noise.
