How to Start the Production of NPK Compound Fertilizer Production Line?

Technical Introduction of NPK Fertilizer Production Line

NPK fertilizer production line or NPK fertilizer  production plant is mainly used for producing npk compound fertilizer. The line adopts rotary drum granulator or double roller granulator which has large capacity for fertilizer granulation equipment, and can be used for producing high, medium and low concentrated npk compound fertilizer.

The npk compound fertilizer production line include automatic batching machine, mixer machine, rotary drum granulator or pan/sisc granulator, belt conveyor, rotary dryer, rotary cooler, rotary screen, rotary drum coating machine, automatic packing machine and chain crusher. We provide complete sets of equipment for npk compound fertilizer production and solutions for our esteemed customers!

Application of NPK Compound Fertilizer  Production Line

1. Rotary drum granulator line has wide adaptability to raw materials which can be urea, ammonium nitrate, ammonium chloride, ammonium sulfate, monoammonium phosphate(MAP), diammonium phosphate(DAP), single superphosphate(SSP), potassium chloride, potassium sulfate, gypsum, lime, etc. You can choose according to market demand and soil test results.
2. Rotary drum granulator production line can produce npk compound fertilizer, organic fertilizer and organic compound fertilizer with the content of N, P, K ranging from 20-48%. It is mainly used for producing spherical particles with a diameter ranging from 1mm to 5mm.

Production Process of NPK Compound Fertilizer Production Line

The NPK fertilizer production process is advanced and reliable. According to the compatibility and crossability of the three raw materials, N-P-K compound fertilizer in different percentage composition can be manufactured applicable for different requirements of soils and crops.

NPK Compound Fertilizer Production Line

  1. Firstly, the raw materials are put into mixer in strict accordance with the technical requirements of each raw material quantity. Then the conveying belt sends the materials to crushing machine.
  2. Then, the crusher machine smashes lump materials into small ones that the fineness meets the required for granulation. Then the conveying belt sends the materials to rotary drum granulator machine.
  3. During granulating, there is a water pump to offer gas and makes fertilizer particles forming easily. The solid fertilizer powder after granulating will rise by the rotation of the cylinder and scroll down under the effect of gravity. At the same time, according to the raw material quantity, add a certain proportion adhesives for granulation. After several times repetition of the same rotation, fertilizer materials gradually form. Next the conveying belt sends the materials to rotary drum drying machine and cooling machine.
  4. There are also draught fans to supply hot air and cold air to drying machine and cooling machine respectively. After drying and cooling is screening process. the coating machine can beautify the materials.
  5. In the process of screening, the qualified materials can be sent to packaging machine by bucket elevator, while others are conveyed back to crusher or granulator to be re-processed.organic fertilizer manufacturing process flow chart
