1. In the solid granulation process of rotary drum granulator, urea, ammonium chloride, ammonium sulfate, potassium chloride and other single base fertilizers are used as raw materials and mixed in a certain proportion (mainly determined by the local market demand and soil test results)).
2. Then use fertilizer mixer to mix the dispersed raw materials evenly and crush them to a certain fineness. Next is the main necessary step – granulation, here you need a drum granulator.
3. The material is sent to the drum granulator by belt conveyor, and agglomerates to form particles through a series of humidification and heating processes.
4. The particles here are only semi-finished products. They need further treatment, including drying, screening, cooling and packaging. After all these steps, high quality compound fertilizer products can be obtained.
Drum granulator is the key equipment of NPK fertilizer granules production line, which is suitable for cold and hot granulation in large and medium-sized compound fertilizer plants. It and ordinary fertilizer granulator are wet granulation. By adding a certain amount of water and steam, the raw materials in the drum will become even and moist in the granulation process. Then, as the drum rotates, the material will combine and roll into particles. The fertilizer particles are spherical with a diameter of 3-4mm.

Why choose?
1. High granulation rate, drum granulator can adjust speed and control granulation.
2. Using solid granulation method, raw materials are easy to obtain and processing is relatively simple.
3. Liquid and steam injection is easy, and pipes and frames are provided.
4. Low investment, low production cost and high return.
5. The drum granulator uses the corrosion-resistant rubber engineering plastic as the lining to better protect the material from drum damage.
6. The particles produced belong to the secondary processing of base fertilizer, so there is almost no environmental pollution problem.
7. High quality steel and gear, stable operation, low noise.
8. Equipped with armrest shovel to help clean the roller.
