1-2 T/h NPK Compound Granular Fertilizer Making Processing Line
Introduction of NPK Fertilizer Production Line
NPK Compound fertilizer production line is widely applied to
produce compound fertilizer and the capacity ranges from
5000-200,000 tons/year. It can granulate NPK, NP, ANP, DAP, MAP,
CAN, SSP and other materials into compound fertilizer particles in
one processing line. This equipment is 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 oval particles with a diameter ranging from 2mm
to 6mm.
Description of NPK Fertilizer Production Line
Our compound fertilizer making machine is mainly composed of the
base support, granulating roller and crushing room and motor
transmission parts; Working under the two shafts, the materials
enters into the hopper, granulated into ball particles by the
strong press of rollers and flow down the crushing room to be
separated into single particles by the required sieve; the powder
size will be returned to the hopper to re-granulate again; the
whole process adopts dry granulation production, especially used to
produce the powder materials with moisture less than 20%;
The final particle size is up to the diameter of the zone on the
rollers, it is customized, can be made into oval shape, bar shape,
charcoal shape, tablet shape, cylinder shape, etc;
Main equipment of NPK fertilizer production line:
| No | Equipment name | Equipment description |
| 1 | Materials cage mill | Crushing materials into small pieces. |
| 2 | Mixing | The mixed material should be mixed completely, then get into
granulator. |
| 3 | Granulator | The rotary drum fertilizer granulator can make the materials into
granules. |
| 4 | Drying | After granulating, the moisture of fertilizer is bit high, it is
not suitable for long-term storage, so we need drying process. |
| 5 | Cooling | The cooling machine is used to cool the hot fertilizer. |
| 6 | Screening | There are some non-uniform particles after sieving, the smaller
particles are sending to mixer, the bigger particles are sending to
crusher. |
| 7 | Coating | The particle surface is not uniform, sleek case, we need to coat
the surface of fertilizer granules. |
| 8 | Packing | After package, ther fertilizer can be sold. |
Features of NPK Fertilizer Production Line
1. NPK fertilizer production line can production NPK fertilizer,
DAP and other materials into compound fertilizer particles.
2. NPK fertilizer production line mainly used for producing
spherical particles with a diameter ranging from 1-3mm.
3. Raw material widely,the production formula easy to operate,used
to produce high,mediumand,low grade of NPK fertilizer.
4. NPK fertilizer production technology is mature,equipments
running stable and high effciency.
