Compound Chemical Fertilizer Plant NPK Fertilizer Granulator Fertilizer Equipment
Introduction of NPK Compound fertilizer line/Compound Chemical
Fertilizer Plant
NPK Compound fertilizer line is widely applied to produce compound
fertilizer and the capacity ranges from 5,000-200,000 tons/year. It
can granulate NPK fertilizer, DAP and other materials into compound
fertilizer particles in one processing line. This equipment can
specially used for manufacturing compound fertilizers with
different concentrations and types, such as organic fertilizers,
inorganic fertilizers, biological fertilizers, and magnetic
fertilizers, etc. It is mainly used for producing spherical
particles with a diameter ranging from 1mm to 3mm.
Advantages of NPK Compound fertilizer line/Compound Chemical
Fertilizer Plant
1. Equipped with advanced fertilizer manufacturing technique, this
fertilizer production line can finish fertilizer granulation in one
process.
2. Adopts advanced rotary drum granulator, granulating ratio is up
to 70%, high intensity of granules
3. The inner cylinder body adopts high quality rubber plate lining
structure which prevents the raw material from sticking on the
plate.
4. Wide adaptability of raw materials, suitable for compound
fertilizer, pharmaceuticals, chemicals, fodder and so on.
5. High-quality, stable performance, anti-corrosion and
wear-resistant materials components, abrasion proof, low energy
consumption, long service lifespan, easy maintenance and operation,
etc.
6. High efficiency and economic returns, and the small part of
feeding back material can be granulated again.
7. Adjustable capacity according to customers' requirements.
Main Components of NPK Compound fertilizer line/Compound Chemical
Fertilizer Plant
The whole compound fertilizer machinery in the fertilizer
production line includes the following machines: fertilizer mixing
machine → fertilizer crushing machine → rotary drum granulator →
rotary drum drying machine → rotary drum cooling machine → rotary
drum coating machine → rotary screening machine → packaging machine
→ spraying granulating system→ belt conveyor → and other
accessories.
Working Flowchart of NPK Compound fertilizer line/Compound Chemical
Fertilizer Plant
The process technology of N-P-K fertilizers is advanced and
reliable. According to the compatibility and crushability 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.
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.
How to Produce the High Nitrogen Compound Fertilizer by Compound
Chemical Fertilizer Plant?
To produce high nitrogen compound fertilizer, one important
equipment is needed in the granulating process: the spraying
system. The melting tank melt the urea and then spray the melted
liquid into the granulating machine so that it will mix with powder
phosphate fertilizer, potash fertilizer and other nitrogen
fertilizer. Then with the help of the granulator, the liquid and
other raw materials will be mixed and granulated. This production
technology is used to produce compound fertilizer or complex
fertilizer with high nitrogen content from 25%-45%.
