Factory source Paper Pulp Screening Machine - 50,000 Tons/year Disc Granulator Production Line – Exceed

Our disc granulator production line mainly produces compound fertilizer with an annual output of 50,000 tons. In general, compound fertilizer contains at least 2 elements of three nutrients (nitrogen, phosphorus, and potassium). With features of high nutrient content, few side effects, and good physical properties, compound fertilizer plays an important role in balancing fertilization, improving fertilizer application efficiency and promoting high and stable yield of crops, our pan granulator compound fertilizer production line is specially designed for fertilizer manufacturers who has a large output requirement. This fertilizer production line can manufacture NPK fertilizer, DAP and granulate other materials into compound fertilizer particles. The process technology of this fertilizer plant is advanced, effective and practical. All fertilizer equipment are compact, high-automatic and easy operation, which is more convenient for mass compound fertilizer production.

Advantage

1.All fertilizer machines adopt anti-corrosion & wear-resistant materials.
2. Adjustable capacity according to customer’ requirements.
3. No waste discharge, energy saving and consumption reducing, environment protecting. Stable operation, simple to maintain.
4. This fertilizer production line can produce not only compound fertilizer with high, medium, and low concentration, but organic fertilizer, inorganic fertilizer, bio fertilizer and magnetizing fertilizer etc. Pan granulator is with high granulation rate.
5. The 50,000 tons/year compound fertilizer production line is high returns on investment, low risk, and payback time is short.
6. With compact layout, the complete set of fertilizer equipment is scientific and reasonable, and advanced in technology.

Working principle

The granulation technological process of compound fertilizer production line can be usually divided into:
1. Material Batching Process
First, raw materials are allocated in strict accordance with the proportion. The raw materials includes urea, ammonium nitrate, ammonium chloride, ammonium sulphate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, single superphosphate, and coarse whiting), potassium chloride, potassium sulfate and etc. The strict allocation ratio of raw materials guarantee the high fertilizer efficiency.
2. Materials Stirring Process
Raw materials are mixed together in flat disc mixer which can stir materials evenly to improve the fertilizer efficiency.
3. Crushing Process
The chain crusher machine will crush the large material into small pieces which can meet the demands of granulation. Then the belt conveyor will send the materials to pan granulator to granulate.
4. Granulating Process
Disc fertilizer granulator adopts arc disc angle structure. The granulation rate can reach above 93%, which has one of the best granulation ratios among all fertilizer granulators. Utilizing the continuous counter-rotating of the equipment and spraying device to drive raw materials rolling in the disc. It can produce uniform and nice appearance granules. Pan granulator is an indispensable machine in compound fertilizer production line.

5. Drying & Cooling Process
After granulating, the granules need to be dried. Belt conveyor transport the granules to the rotary drum drier. The drying machine removes moisture from the particles to increase the intensity of granules. Thus, it is convenient for storage.
After drying, the temperature of fertilizer granules is too high to agglomerate. Thus we need to cool the fertilizer with the use of rotary drum cooler machine. After being cooled,fertilizer granules are easy to package, preserve and transport.
6. Particle Classification Process
Fertilizer should be screened by rotary drum sifting machine after being cooled. Qualified products will be sent into the finished product warehouse by belt conveyor or can be packed directly. Unqualified granules will be re-granulated.
7.Product Packing Process
Packing is the last process in compound fertilizer production line. Full-automatic fertilizer packager is utilized to package finished products. With high-automatic and high-efficiency, it not only achieves accurate weighing, but accomplishes the last technique process excellently. Customers can control the feeding speed and set the speed parameter wilfully.
