Process of non-drying counter-roller squeezing fertilizer
granulator
Introduction of non-drying double-roll extrusion granulator:
The non-drying double-roller extrusion granulator process has a
wide range of applications in powder processing particles. Its
characteristic is that it does not need to humidify the material,
nor does it require heating, and can directly process the material
into particles. It can be used for the processing of organic and
inorganic fertilizer particles, and also for the processing of feed
particles.

Process of non-drying roller extrusion granulator:
1. Add the qualified raw materials into the mixer according to the
ratio requirements and mix them evenly.
2. Transport to the disc feeder, and remove the metallic substances
from the material during the transportation process.
3. The material in the disc feeder evenly enters the extrusion
granulator, and the material is forced to pass between the two
pressure rollers to be squeezed into flakes, and the flakes are
broken into pieces by the coarse crusher under the pressure
rollers. Sieving. The materials on the screen continue to be
crushed and sieved.
4. The semi-finished products are transported to the finished
screening machine. The fine particles after screening are returned
directly to the disc feeder. The large particles are crushed by the
pulverizer and then returned to the disc feeder.
5. The qualified products after screening are transported to the
fully automatic packaging scale for weighing, packaging, and
storage.
Features of non-drying double-roll extrusion granulator:
1. Extrusion granulation does not need to heat and humidify the
materials, which saves investment and energy, and can also be
adapted to the granulation of ingredients containing heat-sensitive
materials, such as ammonium bicarbonate and certain organic
fertilizers.
2. No waste water or waste gas is discharged outside during the
production process, and it will not pollute the environment.
3. The extrusion granulation process is short, easy to operate,
easy to realize automatic production control, and improve
production efficiency.
4. There are no special requirements on the properties and particle
size distribution of the raw materials, so the source of raw
materials is relatively wide.
5. The production is more flexible, and the product plan can be
changed at any time, which is conducive to the production of
special fertilizers in small batches.
6. The product has uniform particle size distribution, no
segregation or agglomeration.
7. The shape of extrusion granulation product is uniform and not
round. Generally, if you need a more round product, you need to
further shape the particles.
