Main features as follows:
1. Production by no drying process, and granulation at room
2. Less investment, quick and good economic returns, reliable
3. Function with granulation, screener with Low Power, no waste
discharge, stable operation,easy maintenanceSuitable for
granulation in many industries, such as fertilizer, feed, and
Applicable raw materials:
The double roller press granulation production line is widely used
in coal, chemical, pharmaceutical, environmental protection and
other industries. The applicable raw materials are: compound
fertilizer, feed, chemical fertilizer, inorganic salt, ammonium
chloride, dust, lime powder, graphite powder, etc.
Working Process of New Type Organic Fertilizer Production Line
At the beginning of the fermentation, chicken manure about 60% of
the material moisture enters the fermentation tank or stacked. The
neophilia microorganisms in the compost use soluble and easily
degradable organic matter as a source of nutrition and energy,
rapidly proliferate, and release thermal energy, which causes the
temperature of the compost to rise continuously.
When the material temperature reaches 60 degrees, the compost
turner starts to turn the material. During the turning process, the
bacteria are fully exposed to oxygen to accelerate the reproduction
of bacteria and reduce the moisture of the material.
Until the temperature does not exceed about 50 degrees, stop
fermentation and leave it there for 5-7 days, then the fermentation
process is finished.
This whole fermentation process is about 20-25 days, but it depends
on the condition of the materials and the local temperature.
2.Screening and Crushing Process
The forklift feeds the fermented materials into the forklift
feeder, and the forklift feeder uniformly transports the materials
to the rotary screen machine through a belt conveyor for screening.
Qualified materials enter the granulation link, and unqualified
materials enter the vertical crusher for crushing. After crushing,
it enters the screen machine for secondary screening.
3.Mixing and Granulation Process
The material enter into mixing machine for mixing with water and
then into the stirring teeth granulator, and the powdery material
can be made into 1.5mm-6mm granules.
4.Drying and Cooling Process
Drying Process: The granules after granulating enter the dryer for
drying. (The heat sources required by the dryer are coal, biomass
particles, natural gas, oil, (waste oil, heavy oil, diesel, etc.),
electric heating, etc.) Induced heat is introduced into the dryer
through the induced draft fan to dry the moisture in the particles
to the surface of the particles.
Cooling Process: The granules after the dryer also contains a large
amount of moisture, which needs to enter the cooler quickly. The
cold air introduced by the induced draft fan quickly cools down and
takes away the moisture.
5.Dust Collecting Caused by the fan in the process of drying and
This process has three steps. The first is the cyclone dust
collector, which mainly collect the small dust particles. The
second is the dust chamber, which mainly collect the dust. The
third is water curtain dust collector also called chimney, which
mainly collect the remain dust after the second step.
6. Secondary Screening Process
This process is used to screen the qualified and unqualified
7. Secondary Crushing Process
This process is used to crush the unqualified granules, maybe too
big or too small, which does not the detailed granule size
8.Secondary Granulation Process
After secondary screening and secondary crushing, then the powder
will come to the granulator again to make granules, in this way,
all finished granules can meet the detailed size requirements.
The cooled granules enter the rotary screen machine for screening,
and qualified granules are transported to packing scale for
packaging. Unqualified granules are transported to chain crusher
for crushing and then re-granulated.
Main equipment included:
|Dynamic batching system|
The dynamic batching machine is suitable for the site of continuous
batching,such as fertilizer batching and coking batching.These
sites have higher requirements on the continuity of the
batching,which generally do not allow the intermediate batching to
stop,and the requirements for the proportioning of various
materials are strict.The dynamic batching system is usually
measured by electronic belt scale or nuclear scale,and the host has
PID regulation and alarm function,which can realize the automatic
control of a warehouse.
Disc feeder machine
The disc feeder machine not only can be used for feeding the raw
materials to granulators,but also can be used a mixer to mixing the
materials,it has long service life, energy saving, small volume,
fast stirring speed and continuous working.
|Double roller press granulator|
Double roller press granulator is the key equipment for compound
fertilizer granulation. It uses squeezing principle to form
fertilizer particles with diameters of 3-10mm in one time. The
shape and size of the ball socket on the roller shell can be
customized by customer. Dry type fertilizer Double Roller
Granulator has higher granulating ratio of over 95%. With no drying
technology, materials will be pressed into ball shape to meet the
requirements of compound fertilizer production in Compound
Fertilizer Double Roller Granulator.
The rotary screening machine is a new type of self-cleaning screen
special equipment after the electric vibrating screener and the
ordinary network type roller screen produced by the domestic
companies.It is widely applicable to sieving of various solid
materials with particle size less than 300mm.It has many
characteristics such as high screening efficiency,low noise,small
amount of dust,long service life,less maintenance,and its screening
capacity is 1t/h-20t/h.
This packing scale is designed for quantitative packaging, It
adopts the integrated structure, and has the characteristics of low
scale height, compact structure, high efficiency, novel appearance,
easy installation and convenient maintenance. The quantitative
precision of the system is 2%.
