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:

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

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.
