NPK Compound Fertilizer Production Line , NPK Production Line
Introduction For Compound Fertilizer Production Line
(1) Compound Organic Fertilizer Making Machine is the key equipment
in compound fertilizer industry.
(2) It is suitable for hot and cold granulation and high, medium
and low concentrations of mass production of compound fertilizer.
(3) The shell of the machine uses special rubber slab lining or
acidresistant stainless lining board
which realizes auto scar removal and de-tumor instead of
traditional drawknife equipment
(4) High balling strength, good appearance, corrosion resistance,
wear resistance, low energy consumption, long service life, easy
operation and maintenance,etc.
Description For Compound Fertilizer Production Line
1, We provide single machine, such as material crusher,material
mixer,fertilizer dryer, fertilizer cooling machine and so on. We
can also provide the whole line of compound fertilizer pellets
production line.
2, Chemical compound fertilizer material is many kinds of chemical
single fertilizer.
3, Chemical compound fertilizer pellets produciton line includes
the organic raw material crushing, mixing,
granulating,drying,cooling,packing.
Raw Material For Compound Fertilizer Production Line
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 |
Flow Chart For Compound Fertilizer Production Line
Compound fertilizer production line usually includes 9 processes,
batching, grinding, mixing, granulating, drying, cooling,
screening, coating and packaging. Batching, mixing, granulating,
drying, and screening processes are necessary. Other processes are
optional based on different capacity.
Main Equipments For Compound Fertilizer Production Line
| No. | Processes | Machines | Function of machines |
| 1 | Batching process | Automatic batching machine | Ratio raw materials by formula |
| 2 | Grinding process | Grinder | Grind granules to powder |
| 3 | Mixing process | Mixer | Mix powder evenly, If necessary, add water, or other micro-elements |
| 4 | Granulating process | Feeding machine | Feed mixed powder into granulator evenly |
| Granulator | Make mixed powder into fertilizer granules |
| 5 | Drying process | Dryer | Dry fertilizer granules to low moisture by hot air |
| Hot stove | Generate hot air to dryer |

| 6 | Cooling process | Cooler | Cool fertilizer granules to normal temperature |
| Cyclone | Collect dust from cooler |
| 7 | Screening process | Screener | Screen out required size from fertilizer granules |
| 8 | Coating process | Coating machine | Coat color, anti-blocking agent, microelements etc on fertilizer
granules |
| 9 | Packaging process | Air compressor | Generate power to packaging machine |
| Packaging machine | Package fertilizer granules into bags |
Features For Compound Fertilizer Production Line
1. The shell of the machine uses special rubber slab lining or
acidresistant stainless lining board
which realizes auto scar removal and de-tumor instead of
traditional drawknife equipment
2. High balling strength, good appearance, corrosion resistance,
wear resistance, low energy consumption, long service life, easy
operation and maintenance,etc.
1. The ball granulator uses the new processes of extrusion
granulation, polishing and shaping ball
2. The ball shaping machine takes the template hole diameter to
control the granule size, change the template according to the
granule size.
3. The granule is even, smooth, round with high strength and good
liquidity.
4. The forming rate of the organic fertilizer is above 95%.
5. The ball shaping machine takes the unique 3-in-1 machine to
finish the whole process of drying with low temperature, cooling
and screening in one time.
6. The equipment is with the low investment and operating cost. The
survival rate of the microbial flora is larger than 90%.
7. The shell of the machine uses special rubber slab lining or
acidresistant stainless lining board
which realizes auto scar removal and de-tumor instead of
traditional drawknife equipment
8. High balling strength, good appearance, corrosion resistance,
wear resistance, low energy consumption, long service life, easy
operation and maintenance,etc.
