rotary drum granulator machine for granulating compound fertilizer
Rotary drum granulator belongs to one of the key fertilizer granulating equipment for making compound
fertilizer granules. which is applyed to both cold and heat granulation with high,medium and large scale
production.this compound fertilizer granulator can make both low and high concentrations of compound
fertilizer granules. The finish inside of the rotary drum granulator is made by a special polyethylene
resistant rubber sheet. The totary granulator has advantages of high rate compound fertilizer granulation
rate, good appearance,corrosion resistance, low energy consumption, easy operation and
maintenance.except this kind of drum granulator,our mutifunctional double roller granulator can also
make compound fertilizer.The high­efficiency fertilizer granulation machine is considered as the most
important equipment in large­scale compound fertilizer production.By adding a certain number of steams
and vapors, raw materials in the rotary drum granulator will become uniformly humid during the
granulation process. Then a series of chemical reactions will occur. In this rotary granulator machine,
the fertilizer particles squeeze each other and roll into fertilizer particles. The uniformly formed fertilizer
particles can be 3­8mm. With the continuous adding of raw materials and rotating of the drum, a large­
scale production as well as the working efficiency will be insured.
Working Principle of rotary Granulator
The main working method is aggregate wet granulation. Through a certain amount of water or steam,
basic fertilizer mixs wet in drum granulator tube body after the full chemical reaction. Under a certain
liquid conditions, in virtue of rotary exercise of the rotating cylinder, so that material granules have an
extrusion stress, reunite to ball.
Features of rotary Granulator
1 the roary drum granulator has high granulation rate about above 70%, the unqualified granules can be
re­granulated;
2 hot steam improves material moisture, which makes compound fertilizer granulation easy
3 the compound fertilizer granulator finished inside of polyethylene makes raw materials difficult to stick
the body,anti­corrosion insulation;

1.Polyethylene plastic plates are fixed in inner drum to prevent sticking and protect drum from corrosion.
2.Drum is placed obliquely in brackets which is made of robust carbon steel plates and channel beam.
3.Inside the drum wall is shoveling plates for easy granulating and cleaning.
4.Rotary drum is made from our vertical lathe, which is strong and solid enough for granulating.
5.Rational design. Motor drives gears and gears drives rotary drum working.
6.Energy conservation,steady granulating process, little noise.
