Based Compound NPK Fertilizer Granules Equipments Line For Pellets
Introduction of NPK Fertilizer Production Line
Complete urea-based compound fertilizer granules equipments line is
widely used to manufacture urea compound fertilizers with different
concentrations and types.And its capacity ranges from 10,000 tons
to 300,000 tons per year.
Working Process Of NPK Compound Fertilizer Making Production Line
It adopts the design solution of extrusion sliding model,the raw
materials pass through double roller,after that,enter into
scattering room, come out as granulation, a sieving was mounted at
the bottom of the machine, which is customized according to
client’s requirement, last, sieve out the granules which is
qualified, the rest of materials return to mixer and be
re-granulated.
Raw Material For NPK Compound Fertilizer Making Production Line
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,

Advantages In NPK Compound Fertilizer Making Production Line
1. Raw material widely,the production formula easy to operate,used
to produce high,mediumand low concentration of compound fertilizer.
2. Low investment cost,good production effect,convenient operation
and maintenance.
3. The production technology is mature,equipments running stable
and high efficiency.
Features of NPK Fertilizer Production Line
1, Simple machine structure
2, Easy operation and maintenance
3, Once forming,no drying process,normal temperature granulating
4. Double shaft power output, each shaft through coupling to drive
its roller to do synchronous work in opposite direction, granule
forming is better and the strength is higher.
5. The design of contraposition adjustment of ball socket is simple
and convenient for the client to adjust by themselves. Provide the
drawing of roller adjustment and operation steps.
6. All machines before leave the factory, had carried out the test
and trial production by professional workers.
