Small investment in extrusion granulation equipment.

Extrusion granulation equipment occupies a small area.

Extrusion granulation equipment is flexible.

Extrusion granulation equipment is easy to install.

Extrusion granulation equipment has low requirements for operators.

some materials due to its own property can only be granulated using this method such as ammonium chloride

Noted：For Material that has a high moisture level and high phosphorus concentration or organic-inorganic fertilizer this type of granulation method can not be used, otherwise the material will stick to the machine.

Crushing of raw materials: Ammonium chloride, monoammonium phosphate, potassium chloride, and urea are crushed by the crusher to the size required by the process.

Mixing of raw materials: the crushed material is mixed in the mixer.

Granulation: the mixed raw materials are formed by extrusion granulator.

Fine sieve: raw materials with unqualified size are returned to the previous process for re-granulation.

Drying: The materials that meet the qualified size enter the drum dryer for drying.

Cooling: The material from the dryer enters the drum cooler.

Fine screening: screen out the finished products with qualified size, and return the rest to the previous process for re-granulation.

Coating: the finished product is coated.

Packing: the finished product is packed by automatic quantitative packing scale, the bag is automatic folded and automatic sewed.

Palletizing: The packaged finished products are stacked by a palletizer.
