Introduction to Compound Fertilizer Production
Compound fertilizer can provide comprehensive nutrients for crops. The production process of compound fertilizer is to combine the main nutrients required by crops (such as trace elements such as N, P, K) by chemical methods, that is, to gather nitrogen fertilizer, phosphate fertilizer, potassium fertilizer and other chemical agents together to make granules suitable for farming, and then apply them to the soil so that crops can absorb the nutrients they need from the soil.
Raw materials for compound fertilizer production
Compound fertilizer is a fertilizer containing two or more of the three basic plant nutrients of nitrogen, phosphorus and potassium, as well as trace elements such as boron, manganese, copper, zinc and molybdenum. Its raw materials can be powdered or lumpy, and there are mainly the following types:
| nitrogen | phosphorus | Potassium | |
| Calcium Nitrate | Urea | Single superphosphate | hot |
| Ammonium bicarbonate | Ammonium chloride | Phosphate rock | Potassium chloride |
| Sodium nitrate | Ammonium nitrate sulfate | Calcium Hydrogen Phosphate | Potassium sulfate |
| Ammonium sulfate | Ammonium Nitrate | Triple superphosphate | Potassium Nitrate |
Compound fertilizer production line flow chart
Compound fertilizer production line usually includes 9 processes: batching, grinding, mixing, granulation, drying, cooling, screening, coating and packaging. Among them, batching, mixing, granulation, drying and screening are required processes, and other processes can be selected according to different outputs.
Main equipment of compound fertilizer production line
| No. | process | machine | Functions of the machine |
| 1 | Batching process | Automatic batching machine | Raw materials according to formula ratio |
| 2 | Grinding process | grinder | Grinding the particles into powder |
| 3 | Mixing process | mixer | Mix the powder evenly and add water or other trace elements if necessary. |
| 4 | Granulation process | Feeder | Feed the mixed powder evenly into the granulator |
| Granulator | Make the mixed powder into fertilizer granules | ||
| 5 | Drying process | Dryer | Fertilizer granules are dried to low moisture content by hot air |
| Hot furnace | Generates hot air to dryer | ||
| cyclone | Collecting dust from dryers | ||
| 6 | Cooling process | Cooler | Cooling fertilizer granules to room temperature |
| cyclone | Collect dust in the cooler | ||
| 7 | Screening process | Filter | Screening of fertilizer granules to the desired size |
| 8 | Coating process | Coating Machine | Coating color on fertilizer particles, anti-caking agent, trace elements, etc. |
| 9 | Packaging process | Air compressor | Powering packaging machines |
| Packing Machine | Pack fertilizer granules into bags |
Characteristics of compound fertilizer production line
The compound fertilizer production line requires little investment,
has quick results and good economic benefits. The entire equipment
process is compact and scientifically advanced. It saves energy and
reduces consumption, does not discharge waste, runs smoothly,
operates reliably and is easy to maintain. The raw materials have a
wide adaptability and are suitable for granulation in compound
fertilizer, medicine, chemical industry, feed and other industries,
with a high granulation rate. The machine can produce compound
fertilizers of different concentrations and types (including
organic fertilizers, inorganic fertilizers, biological fertilizers,
magnetic fertilizers, etc.). In particular, the granulation of rare
earth and electric ammonium compound fertilizers has filled the
domestic gap and is in a leading position in China.
