NPK fertilizer production line factory direct sales
As we all know,the plants needs so many more nutrients than
nitrogen,phosphorus and potassium(also called NPK). While the
current soil can't supply adequate nutrients because of the soil
erosion,pollution and other problems.Now more and more farmers
expect to plant comprehensive NPK fertilizer for larger yield of
their plants,which has promoted more factory to produce NPK
fertilizer with good quality.Our company can provide various
systems and equipments to convert raw feedstock to marketable and
valuable fertilizer.
What's the raw materials can be used to produce NPK fertilizer
1.As the source of nitrogen,urea,ammonium hydrogen
carbonate,ammonium chloride,ammonium sulfate,ammonium nitrate and
other materials which are rich in nitrogen are the best choice
2.As the source of phosphorus,superphosphate,triple
superphosphate,mono-ammonium phosphate,diammonium phoaphate are the
best choice.
3. Potassium sulfate,potassium chloride can be selected as the
ideal source of potassium.
4. Some fertilizer maybe require micro nitrient ,various options
such as Bo,Zn,Mn can be done,it all depends on the soil testing and
fertilizer fomular.
Production process of NPK fertilizer
1.Batching :All kinds of raw materials will be fed into the
electronic belt scale by which will measure the weight and ratio of
each raw material exactly .It is controlled by automatic computer.
2.Granulation:the raw materials will be fed into the granulator to
make into fresh granules.
3.Drying:After granulation, though granules has been formed, but
right now its moisture is too high, so they will be conveyed to the
rotary dryer for drying.
4.Cooling:The temperature of the granules coming out of the dryer
is quite high, then the granules will be send to the rotary cooler
for cooling to further increase the granules strength and reduce
the moisture.
5.Sieving:After cooling, the granules will be pass the sieve to
separate coarse granules and fine powder, final product will be
achieved. The big granules and the fine powder will go through the
grinder and recycle to the granulator, which will make them
participate in the granulation process again .
6. Coating :The granules after sieving will be sent into coating
machine to spray a film on the granules surface ,which can protect
the granules with the air .
7.Packing :After coating ,the granules will be delivered to
automatic packing machine and then storage in bulk.
Remark: This granulation process can be used for producing various
kinds of fertilizer, includes NPK fertilizer, organic fertilizer,
humic acid fertilizer and controlled release fertilizer etc, it can
be used for hundreds of formulas of fertilizer .This production
line is a multi-function production line.
Traits of NPK compound fertilizer making equipments
A.The source of raw feedstock are wide and various,the production
fomular are easy to operate.It can be used to produce high,medium
and low concentration of compound fertilizer.
B.The investment cost is low but the production are effective and
achieve high yield .The whole process is very convenient to operate
and maintain
C.The production technology is mature and various solution can be
offered to our customers.
