Working Process of Bio-organic Fertilizer Granules Production Line:
Organic fertilizer production line is a complete set of equipment from raw
materials collection to the organic fertilizer granules packing.
1) Organic materials fermentation process:
It plays the preliminary but indispensable role in the whole production
line.
Two main types of compost turner are widely used to turn and mix the
compost and accelerate the fermentation speed, Self-propelled compost
turner and hydraulic compost turner.
2) Crushing Process:
The compost lump materials should be crushed before the granulating

---------------------------------------------------------------------------------------------------
---------------------------------------------------------------------------------------------------
process. But we can leave out crushing process when the compost
material is fine enough. Vertical chain crusher and double-shaft horizontal
crusher, two types of crushing machine can be used to crush lump
compost raw materials.
3) Mixing Process:
Two types of mixing machine are applied to mix raw materials in the
fertilizer production line: Horizontal fertilizer mixing machine and
Vertical fertilizer mixing machine.
4) Granulating Process:
Granulating process is the core part in this production line, so we choose
the suitable model of fertilizer granulator according to customers detailed
requirements. Disc granulator machine, Drum granulator machine , Shifts
granulator , flat die granualtor , or ring die granulator in the market . As
usual , ring die granulator can be chosen to granulate the materials evenly
with highest production rate and nice final granules shape.
5) Drying Process:
When granulating, the moisture of fertilizer raw materials should be
30-35 %, and moisture will reduce about 3-5% , so the final moisture is
still more than 25% after granulation process .We should dry the raw
materials if the moisture is more than 25%. Rotary drum drying machine
is mainly used for drying the organic fertilizer granules with a certain

---------------------------------------------------------------------------------------------------
---------------------------------------------------------------------------------------------------
degree of humidity and particle size.
6) Rotary Drum Cooling Machine:
The granules will take higher temperature & humidity .The rotary drum
cooling machine is used for cooling fertilizer to normal temperature as
well as make fertilizer particles stronger.
7) Rotary Drum Screening Machine:
It is used to separate the granules from the large or small particles which
need to be returned for the second crushing and granulating.
8) Rotary drum coating machine is used to coat the fertilizer with wax
and prevent the fertilizer from sticking together.
9) The last process is packaging process: Fertilizer packaging machine
can package bags quantitatively and automatically. We also need some
auxiliary equipment for connection such as belt conveyor, bucket elevator,
etc.

Working Principle
The Ring Die Granulator has two parts :
1, Pelletizer part
2, Polisher (Balling) part
The Pelletizer part with Ring die and rollers system :
The raw material goes into working chamber and fall on the ‘dump tray’, the raw
materials throw into the ring die by centrifugal effect ; The ring die and rollers system
turning drive by reduction gears & transmission which energy from motor . The
pressure come from ring die and rollers system running ,cylinder form are forced
extrusion from ring die hole ,which cutting into small pellets as required by cutting
line .
Polisher (Balling) part are rotation disks :
The small pellets fall onto the disk in the drum ,by high-speed rotating disk throw
onto the wall of drum with circumferential movement , the granules in a circular
motion at the same time also in radial rotation motion due to centrifugal effect .
Mutual friction make the granules with edges and corners into balls gradually due to
granules’ moving . At this moment , Polisher (Balling) part gradually floating on the top ,
final granules overflow along with quantity of granules increased in the drum .
