Introduction for producing compound fertilizer

Compound fertilizer can supply comprehensive nutrient for crops. The production process of compound fertilizer is to combine the main nutrient elements needed for crops (such as N, P, K and other trace elements) by chemical method, that is, gather the nitrogen fertilizer, phosphorus fertilizer, potash fertilizer and other chemicals together and make into particles which are suitable for farming. Then applied into the soil, so that crops can absorb the nutrients they need from soil.

Raw material for producing compound fertilizer

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:

Flow chart of 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.

Characteristics of Compound Fertilizer Production Line

The compound fertilizer production line has less investment, quick results and good economic benefits. The whole equipment process is compact, scientific and advanced. Energy saving and consumption reducing, no waste removal, stable operation, reliable running, convenient maintenance. The adaptability of raw materials is wide, and the machine is suitable for the granulation of compound fertilizer, medicine, chemical industry, feed, etc., and the granulation rate is high. This machine can produce various compound fertilizer with different concentration and different types (including organic fertilizer, inorganic fertilizer, biological fertilizer, magnetic fertilizer, etc.). In particular, the granule for tombarthite and ammonium carbide compound fertilizer fills the domestic void and lead the country.
