Compound Fertilizer Production Line


What Is the Process of Manufacturing Compound Fertilizers?

Crushing for fine powder

Why is it necessary to pulverize before granulation? We know that a compound fertilizer is one that contains at least two nutrients in nitrogen, phosphorus, and potassium. Judging from the raw materials provided by our customers for the manufacture of compound fertilizers, raw materials for compound fertilizers can be obtained from many sources. However, raw materials such as phosphate rock powder, fly ash and urea are prone to agglomeration, so you should crush them with a crusher for better granulation. Of course, if your ingredients are not powder, then you will need a pulverizer or more. We have developed a pulverizer that grinds your material to a fine powder like flour.

Batching for adding other elements

Batching are an indispensable step in making compound fertilizers. Since the raw material of compound fertilizer is not single, you should use a batching machine during production. The raw materials for the manufacture of compound fertilizers are in a certain proportion. If you make the ingredients artificially, the accuracy cannot be accurate. While our batching machine is controlled by a computer, you only need to set your formula ratio on the computer before automatic batching. Our company has multiple batching machines on the batching machine, and you can choose several batching machines according to the ingredients of the raw materials.

Mixing for mixing evenly

After batching, you should mix the raw materials. If you don’t use a blender, you can create granules with uneven distribution of nutrients. A blender can blend several of your powdered ingredients evenly.

Granulating powders into fertilizer granular

The uniformly mixed raw materials can enter the granulator for granulation. Granulation is the most important step in the entire production process. Why do you need granulation? First, granular fertilizers are easier to transport, while powder fertilizers are prone to agglomeration and moisture during transportation. Second, granular fertilizers hold nutrients longer, making fertilizers more effective. Powdered fertilizers are easily affected by external factors, such as being blown away by the wind or running off with rain. Granular fertilizers do not have these problems. We have a selection of different granulators suitable for the compound fertilizer production line.

Screening for unqualified particles

The screening machine is mainly used to screen out qualified products, and the unqualified products are re-granulated through the belt conveyor. On the one hand, it ensures that your compost fertilizer particles are the same size. On the other hand, it increases the productivity of fertilizer and reduces the waste of raw materials. We set up screening machines with different outlets.

Packing for selling

Packaging is the final process on the fertilizer line. Packaged fertiliser is ready for sale. Our company has an automatic packing machine, and the bagging and unloading are done simultaneously, with a fast packing speed. Imported sensors are used, and the measurement accuracy is plus or minus two thousandths.

What Types of Compound Fertilizer Production Lines Can You Choose?

3-5t/h Powdery Compound Fertilizer Production Line

If you want to produce compound fertilizer simply, then powder compound fertilizer production line is a smart choice. The powder production line does not need a granulator for granulation. The main equipment required are pulverizers, batching machines, mixers and packaging machines. Powder compound fertilizer production line can help you produce high-quality compound fertilizer powder with lower production cost. We offer powder compound fertilizer production line with an hourly output of 3-5t.

NPK Compound Fertilizer Factory

NPK fertilizers are a popular choice for fertilizer production. We have different production line options for roller extrusion compound fertilizer production. Since the roller extrusion granulator belongs to dry granulation, this solution can be directly packaged without drying and cooling. Be the choice of many npk manufacturers. This means you can produce npk fertilizer with minimal cost.

30t/h Fertilizer to Granules Compound Fertilizer Production Line

This solution is suitable for compound fertilizer production lines with larger output. It is different from the double roller extrusion compound fertilizer production line, which uses wet granulation to produce compound fertilizers. Taking into account the needs of large-scale compound fertilizer producers, we have developed a suitable plan. This production line uses a rotary drum granulator for granulation, which can produce a maximum of 30t/h of compound fertilizer. If your raw material meet the moisture , no need to add water. If the moisture requirements for granulation are not met,  you should add water. If you consider large scale compound fertilizer production, this is a suitable production process.

What Raw Materials are Needed to Produce Compound Fertilizer?


Nitrogen can make the leaves of the plant large and bright green, so that the leaves can slow down senescence, and the yield is high. Nitrogen fertilizers are often used in production for fast growth of plants. Therefore, we need to apply more nitrogen fertilizer to leafy vegetables. If you have urea, ammonium sulfate, ammonium bicarbonate, ammonium chloride, etc., they are good providers of nitrogen fertilizers.


Phosphorus enables normal crop metabolism and good plant development. At the same time, it improves the drought resistance and cold resistance of crops, and matures earlier. If you want the crops to harveste earlier, you should apply more phosphorus fertilizers. The main varieties of phosphate fertilizers are superphosphate, double superphosphate, calcium and magnesium phosphate fertilizers. In addition, phosphate rock powder, steel slag phosphate fertilizer, defluorinated phosphate fertilizer, and bone meal are also phosphate fertilizers.


Potassium can strengthen the photosynthesis of plants, make the stems tough, resist lodging, and make the seeds plump. The main potash fertilizer varieties are potassium sulfate, potassium chloride and plant ash.

Equipment Configurations for Your Compound Fertilizer Manufacturing Plant

New Type Vertical Crusher

Fermented chicken manure can granulate better after pulverization. The resulting particles are also more beautiful. Our crusher uses a chain-blade composite structure, which can pulverize materials with a moisture content below 40% to a state. The chains of the vertical crusher are high manganese alloy chains. The blades are spring steel, which has the advantage of durable wear resistance. The discharge port is treated with dust suppression to prevent the overflow of dust. The crusher is highly efficient in crushing, does not stick to walls and does not clog materials. It has a viewing window so that you can complete the replacement of worn-out parts in ten

Dynamic Batching Machine

You can choose our dynamin batching machine silo size according to your needs. The contact part between the silo and the material is 304 stainless steel. You can choose several bins of ingredients, and the number of bins can also be customized. The batching system uses computer batching, automatic batching, quantitative measurement, high measurement accuracy, easy operation and reliable operation.

Double Shafts Horizontal Mixer

Why do you need to add a blender? This is because the material coming out of the batching machine is unevenly distributed. If you granulate directly, the distribution of nutrients in fertilizer granules is uneven. Some elements are abundant, and some are even missing. So the mixer is an indispensable step. Our double shafts horizontal mixer uses a double-shaft design to make the material more evenly mixed. Generally, after the dynamic batching machine, it is transported to the mixing tank by the belt conveyor. Homogeneous agitation is carried out by means of helical blades mounted on double shafts. It is worth mentioning that the spiral blades on the double shafts rotate in opposite directions, so that the material is mixed more evenly. The stirring blade is made of high-strength wear-resistant material, which has a longer service life.
