Extrusion Fertilizer Granulator Machine , Double Roller Granulator
The Introduction Of Double Roller Press Granulator
Working principle: adopts the design solution of extrusion sliding
model,the raw materials pass through double roller,after that,enter
into scattering room, come out as granulation, a sieving was
mounted at the bottom of the machine, which is customized according
to client’s requirement, last, sieve out the granules which is
qualified, the rest of materials return to mixer and be
re-granulated.
Equipment Features
1.Double shaft power output, each shaft through coupling to drive
its roller to do synchronous work in opposite direction, granule
forming is better and the strength is higher.
2.The design of contraposition adjustment of ball socket is simple
and convenient for the client to adjust by themselves. Provide the
drawing of roller adjustment and operation steps
3. All machines before leave the factory, had carried out the test
and trial production by professional workers.High capacity extrusion granulator | Humic acid/sludge specific
(particle strength ≥ 15N, energy consumption reduced by 30%)
Product Highlights
✓ Patent twin-screw preloading system (material filling rate
increased by 40%)
✓ Intelligent mold hole self-cleaning technology (reduces downtime
for cleaning)
✓ Wear in resistant steel mold (with a service life of over 10000
hours)
✓ Variable frequency speed control for particle density (adjustable
from 0.8-1.8g/cm ³)
✓ Negative pressure suction system with a dust collection rate of
99%

Product Introduction
The electric motor drives the pulley, and the transmission belt is
transmitted through the speed reducer to a pair of two
high-pressure roller bodies with a sliding mold shell to perform
relative work.
The DZJ-I extruder has two rollers interacting with each other by
the work of a pair of split gears.
The two rollers of the DZJ-II extruder are driven directly by two
output shafts on a dedicated reducer to achieve the purpose of
extrusion.
During the production, raw materials enter the hopper and are
pressed and formed by the high-pressure roller body. After the mold
is released, it flows to the crushing and forming part in the lower
part of the roller body.
The power of crushing and forming is the relative movement of a
pair of crusher rollers driven by the sprocket of the active press
roller shaft via a chain drive.
After crushing and screening in the working chamber, the finished
particles pass through the screen to the discharge then come out of
the machine.
Working Flow:
The roller was first forged and processed from special materials
into roughcast, and then machined by numerical lathe and milling
machine to be finished product. The roller with the features of
rusty resistance, acid and alkali resistance, long service life,
not easy to crack .
input ( If blocked, use chain crusher to deal with ) ----
granulation - screening (select the right sieving hole
diameter)----finished granules---- the next process (optional
equipment: 1, screening machine: the size of the granules will be
more accurate. 2, coating machine: make the appearance of the
granules more good. 3, weighing and package: facilitate the sale
and transportation of products.
