Customer Highly Praised Roller Press Granulator Machine Used For
Dry Chemical Fertilizer
Introduction to roller press granulator machine
Double roller granulator is a kind of fertilizer press machine,
which is used for making fertilizer pellets. Its pellets are oval
shape. It can work under normal temperature, but yields high
granulation ratio.

Working principle of roller press granulating machine
There are mainly five steps turning materials into granules with
this double roller press granulator machine.
1. Firstly, you need put the mixed fertilizer materials on the belt
conveyor, then the powdery raw material will enter the double
roller press granulator.
2. The material is forced between the two rollers below for
extrusion, and the two rollers rotate relative to each other.
3. Under the strong extrusion pressure, the delivered materials
become a cake shape with a stick mold, and the cake shape bar
enters the crushing workshop.
4. The crushed materials are broken by the broken axis, and are
screened through the screen below the crushing chamber.
5. Qualified particles are sent to the outside through the air. And
the sifted powder material will be sent back to the raw material
warehouse for the second roll.
Features of roller press granulating machine
The structure of the machine adopts granulation, molding and
screening as one, which has the advantages of good looking, simple
operation and low energy consumption.
The main parts, such as rollers, are made of a new type of metal
with corrosion resistance, wear resistance and impact resistance of
roller press granulator. The DZJ-II machine not only has the above
characteristics, but also has the updated frame part has also been
upgraded. The bearing frame is selected as the whole component with
high quality anti-corrosion casting. With more stable performance,
it can greatly improve the operation life of the rolling bearing
and shaft.
For the transmission part, we use the dual input transfer mode,
which not only improves the input power ratio, but also ensures the
lubrication and sealing performance of the transmission gear. The
machine has the advantages of compact structure, good stability,
good sealing, low noise, convenient operation and easy maintenance.
After the new machine launched, it was deeply liked by masses of
users.
Advantages of roller press granulating machine
1. 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. 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.
2. 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.
3. Environmental friendly. Reliable motor is used, no three wastes
releasing which is environmental protection.
4. 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.
Application of roller press granulating machine
Double roller press granulator machine can be widely used in many
businesses. It can granulate pellets with a number of different
kinds of raw materials. Here are some of the applications for you
to refer to.
1. Compound fertilizer granulation.
2. Solid chemicals granulation.
3. Pharmaceutical granulation.
