Carbon Steel Rotary Drum Granulator For NPK Compound Fertilizer
Production Line
Introduction For Compound Fertilizer Production Line
Rotary drum granulator used for NPK compound fertilizer production
line is the key machine in the fertilizer producing line.Its
quality directly decides the quality and apperance of the
fertilizer.So,it’s better to choose the appropriate granulator for
you.
Raw Material For Compound Fertilizer Production Line
1. Urea,ammonium sulfate,ammonium chloride,producyion.
2. Monoammonium phosphate,diammonium phosphate,calcium
superphosphate,calcium-magnesia phosphate fertilizer
3. Potassium chloride,potassium sulphate,potassium sulphate
magnesium
Main Equipments For Compound Fertilizer Production Line
1. Crushing machine: vertical grinder and horizontal grinder
2. Mixing machine: vertical mixer and horizontal mixer
3. Granulation machine:disc granulator roller granulator and drum
granulator
4. Rotary dryer:Drying fertilizer granule after granulating to low
down moisture
5. Rotary cooler:Cooling fertilizer granule to make it stable.
6. Coating machine:Coating machine to produce different colors
fertilzier granule
7. Screening machine:Grading non-standard fertilizer granules from
standard fertilizer granules.
8. Packing machine:Pack fertilizer granule into 10/20/50kg bags.

Features For Compound Fertilizer Production Line
1. Adopt plastic plate or stainless steel plate lining, materials
not easy to stick on the inner wall of the machine.
2. Stable operation, easy maintenance, high efficiency, low energy
consumption.
3. Bubbled into steam heating, and improve the material
temperature, make the material into the ball low moisture, improve
the efficiency of drying;
4. with rubber lining engineering plastics, raw material is not easy
to stick, and anti-corrosion insulation effect;
5. large output, low power consumption, low maintenance cost.
Characteristic For Compound Fertilizer Production Line
1) It is used for producing high,medium,low concentration of
compound fertilizers,application scope is wide ,the investment cost
is low.
2) The shell of the granulator uses a special
rubber-lined,anti-corrosion,long service time.
3) The intensity of being ball is high,quality of the appearance is
perfect,operation and maintenance are convenient.
