Ammonium Sulphate Pellets Making Roller Press Granulating Machine
Introduction to roller press granulating machine
Roller press 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.

Working principle of roller press granulating machine
After you start the machine, the motor will drive belt pulley,
triangle belt and speed reducer. Then the fertilizer press
granulator begins to work. Next, you should feed mixed powder
materials into extrusion granulating part through a feeding hopper.
Then two roller sheets extrude air out of powder material and
feeding material will be into slices under strong press forces.
The following is that the extruded material is going to enter the
crushing part inside a double roller granulator. Here, the big
tablets will be smashed into the required fertilizer granules.
Lastly, our roller granulator will discharge your qualified
granular fertilizer and return powder materials to pelletizing once
more.
Features of roller press granulating machine
1. The roller press granulator is without drying process, room
temperature granulation, a molding, less investment, quick effect,
and good economic returns.
2. Compound fertilizer on roller extruding and granulating machine
power of small reliable operation, no waste discharge, stable
operation, convenient maintenance, process layout is reasonable,
advanced technology, low production cost.
Advantages of roller press granulating machine
1. Reasonable structure. This roller fertilizer granulator machine
is compact in design, light in fertilizer granules 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. 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.
Application of roller press granulating machine
The double roller press granulating machine is used in chemical
fertilizer production line & other products production, such as
urea, ammonium nitrate, potassium chloride etc.
