Introduction of rotary drum granulator for fertilizer
The rotary drum granulator (also called a rotary granulator) is a key machine in the compound fertilizer industry—it shapes materials into specific granules. It works for both cold and hot granulation processes, and can produce large quantities of compound fertilizers, including high-concentration, medium-concentration, and low-concentration ones.
Its main working principle is wet granulation. Specifically, we add a controlled amount of water or steam to the basic fertilizer ingredients. This lets the ingredients react fully inside the drum. At the same time, the pressure between particles makes the materials clump into round granules, which finally completes the granulation.

Applications of Drum Granulators
A drum granulator is highly versatile and can process a wide range of raw materials, primarily used in fertilizer production (the core application field) and also applicable to some industrial particle processing scenarios. The specific raw material categories are as follows:
Core Application: Raw Materials for Fertilizer Granulation
This is the most common use of drum granulators, suitable for both organic and inorganic fertilizer production, with raw materials including:
Inorganic fertilizer (compound fertilizer) raw materials:
Nitrogenous fertilizers: Urea, ammonium nitrate, ammonium sulfate, ammonium chloride (usually mixed with other materials to avoid caking).
Phosphatic fertilizers: Superphosphate, diammonium phosphate (DAP), monoammonium phosphate (MAP), calcium magnesium phosphate fertilizer.
Potassic fertilizers: Potassium chloride, potassium sulfate.
Mixed nutrients: Blends of the above nitrogen, phosphorus, and potassium (NPK) raw materials, or with trace elements (such as boron, zinc, iron compounds) added.
Q&A
Q: Does your factory offer after-sales service for the equipment sold?
A: Yes. We provide after-sales service coverage for all equipment purchased from our factory.
Q: How much NPK fertilizer can a drum granulator produce in one year?
A: The TIANCI drum granulator can produce 10,000 to 600,000 tons of NPK compound fertilizer annually. To meet customers' demands for higher output, we offer customization services.
Q: Could you please confirm whether installation services for the drum granulator are available following its purchase?
A: Yes. After the equipment arrives at your factory, we will send experienced engineers to your site to provide installation guidance and ensure the equipment operates normally.
Q: Could you please specify the hourly output range of your drum granulator?
A: The standard hourly output of our drum granulator ranges from 1 to 25 tons. If you have higher output demands (e.g., over 25 tons per hour), we can tailor a customized solution based on your specific production needs.
