DAP NPK Compound Fertilizer Granulator With Double Roller
Working Process of compound fertilizer granulator
The compound fertilizer granulator machine is the representative of
extrusion granulator. Dry materials are compressed into hard &
dense blocks at a pressure, which is the Extruding Process. Block
materials are crushed, screened and granulated later, which is the
Granulating Process. The functions of extrusion are to squeeze the
air between particles out, and to make the distance between
particles near enough to give rise to interaction forces. The
particle hardness of roller compaction granulation granules is
formed mainly due to attraction between the molecules. Our double
roller press machine is continuous extruding granulation of
positive-displacement.
Process advantages of compound fertilizer granulator
1. The compound fertilizer granulator belongs to dry granulation.
It is not necessary to adjust the dryness and humidity of the
material during the granulation process, and there is no need to
increase the drying equipment.
2. Compound fertilizer granulators can be used to process granules
containing heat-sensitive materials.
3. Because it is dry granulation, no waste water or waste gas will
be emitted during the production process.
4. The compound fertilizer granulator has simple process, easy
automatic control, and high production efficiency.
5. The flexibility of the roller extrusion compound fertilizer
granulator is good, and the fertilizer production plan can be
unaffected at any time.
6, the uniformity of the particle size of the roller extrusion
granulation is a significant advantage, because the ball socket
size of the roller is the same.
Application of compound fertilizer granulator
The compound fertilizer granulator has wide adaptability of raw
materials is DAP, SSP, GYPSUM, SHEEP MANURE, COW MANURE , chicken
manure, pig manure, bentonite and other animal poultry manure waste
and so on. the roller press granulator production rate is high. It
can produce all kinds of high concentration with a various
fertilizers including organic fertilizer, Inorganic fertilizer,
compound fertilizer, etc. especially rare earth fertilizer, potash
fertilizer, ammonium bicarbonate series for this fertilizer double
roller granulator. the fertilizer press machine makes up the gap
leading the position in domestic. when using this granulator as a
whole fertilizer production line, it does not need a rotary dryer.
