Fully automatic compound fertilizer production line
Introduce:
Automatic compound fertilizer production line equipment includes automatic batching machine, grinder, mixer, drum granulator, dryer, LQ series cooler, screening machine, automatic packaging machine, coating machine, automatic weighing machine. What are the functions of these devices? The functions, uses and prices of these devices will be introduced in detail below.
Compound fertilizer making process:
1. Raw material ingredients: urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, heavy calcium, ordinary calcium), potassium chloride (potassium sulfate) and other raw materials are equipped in a certain proportion (according to Market demand and soil testing results in various places).
2. Mixing of raw materials: Stir the prepared raw materials evenly to increase the uniform fertilizer efficiency content of the overall fertilizer particles.
3. Raw material granulation: Feed the uniformly stirred raw materials into the granulator for granulation (rotary granulator or extrusion granulator can be used).
4. Granule drying: The granules made by the granulator are sent to the dryer, and the moisture contained in the granules is dried to increase the strength of the granules and facilitate storage.
5. Granule cooling: The temperature of dried fertilizer granules is too high and easy to agglomerate. After cooling, it is convenient to store and transport in bags.
6. Particle classification: The cooled particles are classified, the unqualified particles are crushed and re-granulated, and the qualified products are screened out.
7. Finished film: Coating qualified products to increase the brightness and roundness of the particles.
8. Finished product packaging: Pack the film-coated particles, that is, the finished product, and store it in a ventilated place.
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.

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.
