Double Roller Extrusion Granulator
Introduction of Double Roller Press Machine
Our roller fertilizer making machine is a key fertilizer
equipment in compound fertilizer granulation. Roller-type
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 compactor granulator will bring investors bigger economic
returns. It can be used in compound fertilizer production with
high, medium and low concentration.
Advantages of Double Roller Fertilizer Granulation Machine
1.Reasonable structure. This roller 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 press 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
roller compactor 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 Process of Roller Fertilizer Making Machine
The double roller 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.
Application of Roller Press Machine
The double roller fertilizer making machine is used in 30,000 t/y
compound fertilizer production line & other products manufacturing,
such as capsule filling particles, pigments, detergents, catalysts,
fertilizer, inorganic salts, calcium hypochlorite, pesticides,
oxides, etc., industrial dust recovery materials: such as foundry
dust, lead, zinc, aluminum dust, converter dust, grinding dust,
etc.
Remark:finished granules by this roller press machine is oval
shape, if you want round ball shape granules,a ball shaping machine
can help, ball shaping machine is used to make cylindrical and oval
shape granules (pellets) into round ball shape granules. It adopts
high speed rotation working principle to make round ball pellets.
