Compound Fertilizer Granulator Double Roller Press Granulator
Machine
Introduction of compound fertilizer granulator
Our compound fertilizer granulator is a key fertilizer equipment in
compound fertilizer granulation. Roller-type compound fertilizer
granulator is a new-designed fertilizer roller compaction
granulation device developed & researched by ourselves. Materials
are granulated at room temperature, and there is no drying process,
more energy-saving and cost-reducing. With the characteristics of
small investment, large profits, and quick results, the double
roller compound fertilizer granulator will bring investors bigger
economic returns. It can be used in compound fertilizer production
with high, medium and low concentration.
Advantages of compound fertilizer granulator
1.Reasonable structure. This roller compound fertilizer granulator
machine is compact in design, light in weight, steady in rotation,
with higher precision and stiffness. The press rollers, which are
accommodated to press different shapes/sizes materials, adopt new
metal which is resistant to corrosion, oxidation, and abrasion. The
double roller compound fertilizer granulator machine is also with
perfect performance, reliable operation, easy in maintenance and
long service life.
2.Wide application scope. At present, there are 20 kinds of raw
materials being applied in this extrusion granulation, such as
urea, ammonium nitrate, potassium chloride, bentonite, chicken
manure, pig manure, and other animal poultry manure waste etc. In
addition, it can replace the product formula flexibly in a short
time by adopting extrusion granulation technology. A set of device
can produce over 30 product formulas.
3. Making raw materials to fertilizer granules at once time. The
compound fertilizer granulator has higher granulating ratio of over
85%. The granular shape of finished products pressed by double
roller granulator is elliptical.
4. Environmental friendly. Reliable motor is used, no three wastes
releasing which is environmental protection.
5. Lower energy consumption. There is no drying process. It doesn’t
need oil or gas fired, bringing fertilizer investors good economic
returns with low investment.
Working principle 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 compound
fertilizer granulator machine is continuous extruding granulation
of positive-displacement.
