According to relevant information, the complete NPK compound fertilizer production process flow can usually be divided into: raw material batching, raw material mixing, raw material granulation, particle drying, particle cooling, particle classification, finished product coating, and final finished product packaging. The complete set of FPC compound fertilizer equipment has low investment, quick results and good economic benefits. The complete set of equipment has a compact flow layout, scientific and reasonable, energy-saving and consumption-reducing, stable operation, reliable operation and convenient maintenance. The raw materials have wide adaptability, suitable for the granulation of various raw materials such as compound fertilizer, medicine, chemical industry, feed, etc., and the product granulation rate is high. It can produce compound fertilizers of various concentrations and various types (including organic fertilizer, inorganic fertilizer, biological fertilizer, magnetic fertilizer, etc.).

What is detailed NPK compound fertilizer production line?

The process flow of NPK compound fertilizer production line is as follows:

• 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).
• Mixing of raw materials: Stir the prepared raw materials evenly to increase the uniform fertilizer efficiency content of the entire fertilizer particles.
• Raw material granulation: send the uniformly stirred raw materials to the granulator for granulation (rotary drum granulator or extrusion granulator can be used).
• 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.
• Granule cooling: The temperature of dried fertilizer granules is too high and easy to agglomerate. After cooling, it is convenient for bagging storage and transportation.
• Particle classification: The cooled particles are classified, the unqualified particles are crushed and re-granulated, and the qualified products are screened out.
• Finished film: Coating qualified products to increase the brightness and roundness of the particles.
• Finished product packaging: Pack the film-coated particles, that is, the finished product, and store it in a ventilated place.

NPK compound fertilizer contains two or more kinds of macroelements, which can provide rich nutrition for the growth and development of soil and plants. What should be paid attention to when applying NPK compound fertilizer?

There are different concentrations of compound fertilizer, we should pay attention to choose the appropriate concentration. At present, most compound fertilizers are distributed according to the average nutrient status of soil types and the proportion of fertilizer required by crops in a certain area. There are high, medium and low concentration compound fertilizers on the market.

Generally, the low concentration of total nutrients is between 25% ~ 30%, the medium concentration is between 30% ~ 40%, and the high concentration is more than 40%. And crops. Generally speaking, high concentration compound fertilizer is used for economic crops with good quality, less residue and high utilization rate. The concentration of compound fertilizer is high. Avoid direct contact between seeds and fertilizer. The nutrient content of compound fertilizer is high. If the seeds or seedling roots are directly contacted, the emergence of seedlings will be affected, and even the roots will be burnt. When sowing, seeds should be mixed with acupoints, and compound fertilizer should be applied in strips with an interval of 5-10 cm.

Matters needing attention in application of NPK compound fertilizer

It is necessary to pay attention to the nutrient composition of compound fertilizer with different proportion of raw materials. Different brands and concentrations of compound fertilizer use different raw materials, which should be selected and used according to the types of soil and crops. The compound fertilizer containing nitrate is not suitable for leaf vegetables and paddy fields. It is not suitable to use compound fertilizer containing ammonium ion, potassium chloride or chloride ion in saline alkali soil, potassium sulfate in crops or saline alkali soil, and potassium sulfate in paddy field and acid soil, otherwise it will reduce fertility and even poison crops.

The compound fertilizer containing two or more kinds of large elements is easy to volatilize or lose with the rain, and the phosphorus and potassium are fixed by the soil, especially the mobility of phosphorus in the soil is small, and it is not easy to be absorbed. The crop root system is on the surface, which is not conducive to deep root system. The drought condition in the fertilizer can not be dissolved, and it is worse in the development, so the compound fertilizer should go deep into the soil.
