Main Components of 50,000 ton Compound Fertilizer Production Line

1.Material ingredient: Urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, TSP, SSP), potassium chloride (potassium) and other raw materials are dispensed according to a given proportion (according to the market demand and the soil test results). N, P, K, additives, and trace elements are introduced into proportioner through the belt weigher in fixed proportion. According to formula ratio, all raw materials flow to the belt uniformly, which can be called Premix. It ensures accurate formula, and achieves an efficiently continuous processing.
2. Raw materials mixing: transforming proportionate raw materials to disc mixer which is used to evenly mix all materials to improve the uniformity content of fertilizing ingredient.
3. Granulating: well-mixed raw materials are transformed to rotary drum granulator for pelletizing. The reason we choose rotary granulator is that rotary drum granulator is with a rather large-output of fertilizer granules. It is suitable for large-scale compound fertilizer production. It is an essential and indispensable part in the whole line.

4. Fertilizer drying: compound fertilizers need to be dried to a certain moisture content after pelletizing to increase the physical character. After being dried, the fertilizer are easier to storage.
5. Fertilizer cooling: temperature of fertilizer pellets after drying is too high, very easy to agglomerate. after cooling, the fertilizer granules are easier for bagging, preserving, and transporting.
6. Fertilizer grading: we use rotary screening machine to screen the end products. All fines and large particles can be screened out using our rotary drum screening machine. Then, fines being transported by belt conveyor are back to horizontal mixer for remixing and re-granulating with raw materials. While large particles needs to be crushed in chain crusher before re-granulation. Quasi-finished products are conveyed into compound fertilizer coating machine. In this way, a complete production cycle is

formed.
7. Fertilizer coating: The qualified products are coated in this process to increase the brightness and roundness.
8. Fertilizer packaging: our automatic fertilizer packager is specially designed and manufactured for end products bagging. Independent suspension sensor makes sure that signals can be relayed stationary and effectively, and also improves weighting precision. As feeding speed is controlled by controller, customers can can set the speed at random.
