Raw Material For

NPK Compound Fertilizer Making Production Line

Compound fertilizer is the fertilizer containing two or all three of the three basic plant nutrients—Nitrogen, Phosphorus, and Potassium, as well as microelements, such as B, Mn, Cu, Zn, and Mo. The raw material can be powder or bulk, mostly are as below:

Nitrogen		Phosphorus	Potassium
Calcium nitrate	urea	Single superphosphate	Kainit
Ammonium bicarbonate	Ammonium chloride	Rock phosphate	Potassium chloride
Nitrate of soda	Ammonium sulphate nitrate	Dicalcium phosphate	Potassium sulphate
Ammonium sulphate	Ammonium nitrate	Triple superphosphate	Potassium nitrate

■ Advantages and Characteristics

Advantages In NPK Compound Fertilizer Making Production Line

1, Productive Technology: this machine by the process of high temperature drying, disinfection, decomposition and dried can make fresh chicken which moisture is 65% becomes pure organic chicken which moisture is below 13%.

2, Final Products: the organic fertilizer has many kinds of necessary nutrients for the crops. After scientific research departments detection: the fertilizer of nitrogen content is 2.6%, the phosphorus content is 3.5%, potassium content is 2.5%, crude protein content is 16-25%, organic matter content is 45%. is the best choose fertilizer for planting pollution-free green food , can also used for feeding the fish, cattle, pigs, etc.

3, Drum drying have high mechanization degree, bigger production capacity, can run continuously.

4, Structure is good and simple, material through the resistance of barrel, easy to operate.

5, Less malfunction, lower maintenance cost, low power consumption.

6, Widely used, uniformity is good of the products drying.

7, In the meantime of drying can also achieve the purpose of sterilization and deodorization.

Characteristics of NPK Fertilizer Production Line

Energy saving and consumption reducing, no waste removal, stable operation, reliable running, convenient maintenance. The adaptability of raw materials is wide, and the machine is suitable for the granulation of compound fertilizer, medicine, chemical industry, feed, etc., and the granulation rate is high. This machine can produce various compound fertilizer with different concentration and different types (including organic fertilizer, inorganic fertilizer, biological fertilizer, magnetic fertilizer, etc.).
