Complaint
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
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.
