Introduction of Rotary Drum Granulator

Rotary drum granulator is a critical machine in fertilizer production line. It is applied to cold and hot granulation in large and medium size compound fertilizer factory.

By adding a certain number of water, steams and vapors, raw materials in the rotary drum will become uniformly humid during the granulation process.

Then materials will be connect together and rolled into particles because of the drum rotating. The formed fertilizer particles are of 3-4mm in ball shape.

Feature of Rotary Drum Granulator

1. Easy operation and maintenance, stable working in fertilizer production line.

2. High granulating rate: the granulation ratio can be 70% and strength is higher

3. Long service life: inning with anti-corrosive rubber engineering plastic which can better protect raw materials harm to the inner of drum

4. Large capacity with low power in NPK fertilizer production line.

5. Steam and liquid spraying available

Advantage of Rotary Drum Granulator

1. High fertilizer granulation ratio, speed can be adjusted as granulating can be controlled

2. Liquid and steam injecting easily, pipe and frame provided in rotary drum granulator supplier

3. Use anti-corrosive rubber engineering plastic as inner lining, better protect materials harm to the drum

4. Super quality steel and gear, stable working with low noise

5. Rational shoveling plates equipped to help drum cleaning

6. Various materials testing for different formula fertilizer processing

Working Principle of Rotary Drum Granulator

1. Raw materials go into the rotary drum granulator for fertilizer processing by conveyors.

2. They will be better mixed and granulated with the constant rotating of drum.

3. Materials will form one rolling bed and move along a certain path.

4. Under the extrusion force and rolling, the powders will be one small particle with liquid injecting.

5. These small particles will be the core and then attach other powders around to form the final granules.

6. There is angle in drum installation, granules will be out from rotary drum granulator outlet easily.
