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.
transforming proportionate raw materials to disc mixer which is used to evenly mix all materials to improve the uniformity content of fertilizing ingredient.
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.
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.
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:
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.
The qualified products are coated in this process to increase the brightness and roundness.
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.
Features of 50,000 ton Compound Fertilizer Production Line:

Compound Fertilizer Production Line Main Components
The whole compound fertilizer machinery in the fertilizer production line includes the following machines: fertilizer mixing machine → fertilizer crushing machine → rotary drum granulator → rotary drum drying machine → rotary drum cooling machine → rotary drum coating machine → rotary screening machine → packaging machine → spraying granulating system→ belt conveyor → and other accessories.
The process technology of N-P-K fertilizers is advanced and reliable. According to the compatibility and crossability of the three raw materials, N-P-K compound fertilizer in different percentage composition can be manufactured applicable for different requirements of soils and crops.
Compound Fertilizer Production Line Working Flowchart 1. Firstly, the raw materials are put into mixer in strict accordance with the technical requirements of each raw material quantity. Then the conveying belt sends the materials to crushing machine.
2. Then, the crusher machine smashes lump materials into small ones that the fineness meets the required for granulation. Then the conveying belt sends the materials to rotary drum granulator machine.
3. During granulating, there is a water pump to offer gas and makes fertilizer particles forming easily.
The solid fertilizer powder after granulating will rise by the rotation of the cylinder and scroll down under the effect of gravity.
At the same time, according to the raw material quantity, add a certain proportion adhesives for granulation.
After several times repetition of the same rotation, fertilizer materials gradually form.
Next the conveying belt sends the materials to rotary drum drying machine and cooling machine.
4. There are also draught fans to supply hot air and cold air to drying machine and cooling machine respectively. After drying and cooling is screening process. the coating machine can beautify the materials.
5. In the process of screening, the qualified materials can be sent to packaging machine by bucket elevator, while others are conveyed back to crusher or granulator to be re-processed.
How to Produce the High Nitrogen Compound Fertilizer?
To produce high nitrogen compound fertilizer, one important equipment is needed in the granulating process: the spraying system.
The melting tank melt the urea and then spray the melted liquid into the granulating machine so that it will mix with powder phosphate fertilizer, potash fertilizer and other nitrogen fertilizer.
Then with the help of the granulator, the liquid and other raw materials will be mixed and granulated.
This production technology is used to produce compound fertilizer or complex fertilizer with high nitrogen content
