An energy saving granulating method of ammonium sulfate fertilizer

Ammonium sulfate is mainly used as nitrogen fertilizer in agriculture. Its advantages are relatively small moisture absorption and not easy to agglomerate. Compared with ammonium nitrate and ammonium bicarbonate, it has excellent physical properties and chemical stability. Ammonium sulfate is usually made into granular fertilizer for agriculture, so how to make this fertilizer?

Ammonium sulfate as a quick acting fertilizer has a good effect. The synthetic ammonium sulfate fertilizer is white crystal. The by-products from coking or other petrochemical production are greenish green, brown or yellowish. The content of ammonium sulfide is 20-21%, containing a very small amount of free acid. Double roller press granulator is suitable for pelletizing this material. Tianci fertilizer machine manufacturers specializes in the production of compound fertilizer equipment and fertilizer production line, and provides dry extrusion granulation manufacturing process to solve the granulation problem of ammonium sulfate fertilizer.

The whole machine of double roller press granulator designed by us is divided into four parts:
double roller press granulator
1. Frame part: The main body of the whole extrusion granulator is installed and fixed on the frame. The frame of the machine is welded by channel steel, with stable structure and corrosion-resistant material, so as to extend the service life and meet the specific process requirements.

2. Transmission connection part: The motor drives the belt pulley, V-belt and reducer to make the head work. In addition, the chain wheel and chain constitute the transmission chain to the crushing and separating part.

3. Head working part: It is transmitted to the transmission roller shaft by the transmission wheel through the pin coupling, and the two roller shafts are guaranteed to run synchronously by a pair of open gears.

4. Crushing and separation part: The material flows to the crushing chamber at the lower side after being extruded by the roller, and the particles and returned materials can be separated by the rotation of the biaxial mace.

The ammonium sulphate fertilizer manufacturing process technology designed by us, the whole fertilizer production line equipment with the roller press granulator, can realize the operation of quantitative weighing, sewing and packing of ammonium sulphate fertilizer, effectively reduce the labor intensity and greatly improve the production efficiency.
