Production technology

1 Solid urea or ammonium nitrate (ammonium nitrate phosphorus, etc.) after heating and melting into molten liquid, can also be directly used after evaporation and concentration of molten liquid. The phosphate fertilizer, potassium fertilizer, filler and additives are added into the molten liquid to make the mixed slurry.

2. The mixture will be sent into the tower pelletizing machine for spraying granulation, through the pelletizing machine spraying into the granulation tower material, in the process of falling from the tower, and the gas resistance rising from the bottom of the tower interaction, and after the heat exchange to fall to the bottom of the tower, into the bottom of the particle material, after screening surface treatment to get granular compound fertilizer.

Product features:

Compared with the common composite fertilizer manufacturing process, the tower granulation process has the following advantages:

1. The fertilizer produced has high compressive strength and fast water solubility.

2. The nutrients are even, so that the crops grow evenly and the overall growth is good.

3. High yield, few return material, saving electricity consumption of coal fuel.

4. High utilization rate of fertilizer. High tower compound fertilizer, its nutrient release is uniform, fertilizer effect is prolonged, so that its fertilizer utilization rate has been improved.

5. Suitable for re-coating, reduce production cost.

6. Good operating environment, no three wastes discharge, belongs to clean production technology.

7. Large output per unit time, stable product quality, low operating cost, less energy consumption, easy to operate.
