How make organi fertilizer granules with drum granulation equipment

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.

Dry Granulation Fertilizer Production Technology

Non drying fertilizer granulation technology is mainly used for products with low water content. Generally, moisture content below 10% is a critical value. (some materials can reach 16%, for example, some contain only crystal water). Some organic fertilizer manufacturing processes have low water content, no need to dry, and save energy.

Dry granulation

The double roller granulator belongs to drying granulation equipment without drying process. It has high granulation density, good fertilizer efficiency and high organic content. The particles are flat and round, suitable for compound fertilizer.

Most of the particles produced by dry granulation are irregular particles (such as ordinary particle size potassium fertilizer), and their shape is similar to the shape of small gravel. The double roller granulator can produce all kinds of high, medium and low concentration NPK compound fertilizer and organic-inorganic compound fertilizer granulation, which meets the requirements of energy conservation and environmental protection.

Fertilizer granulation technology without drying extruder

The dry powder extruder consists of five parts: frame, head, pressure reducer, motor and crusher. It has the advantages of simple structure, high stability, convenient operation and maintenance, and strong adaptability of raw materials.
