Chemical npk Fertilizer bentonite granules production line
Product description
The importance of powder granulating technology as one of the most
important branches of powder particles processing treatment is
increasingly clear with the demand of environment protection and
improvement of automation of the production process. “Powder
products will become granules” has become the necessary trend of
powder-after-processing technology in the world.
DH series dry roll press granulator adopts dry rolling technology
to compress the powdery materials with moisture content ≤ 5% into
pieces or tablets, then going through the processes of breaking
into granules and screening to make the lump materials into
granules that meet the requirements of application. Dry roll press
granulator mainly depends on the manner of external pressure to
force the material going through the gap between two relatively
turning rollers to compress into laminar particles. During course
of roller pressing, the real density of materials can increase
1.5~3 times thus reaching certain demands of granular strength.
Working principle
* We use mixer mix the raw material.---Mixer
* We use bucket elevator lift the material up to the
silo.----Bucket elevator and Silo
* The COMPACTOR compress the raw material by double rollers,the
roller shape is oval ball, oblate ball ,square granule----compactor
(including three parts: dosage screw feeder, forced feeder and
flaking machine.)
* Then we get the oval ball/oblate ball/ square shape products.
* Finally, we will use rotary screen to sieve the final products,
the unqualified products, such as dust, big granular and very small
granular will be recycled for the next time granulation process.
--------Rotary Screen
* Next we use the second time rotary screen, the purpose is we want
to get better result of regular shape granules after second time
screening, the appearance of irregular shape granular will looks
more beautiful. -------Second Time Rotary Screen (if you don’t need
this, you can delete this process.)
* The last step is automatic packaging machine. This machine will
help you pack the final granular into bags. ----Automatic Packaging
Machine
Granulator supporting equipment
In addition to the pellet machine,we can also provide the whole
supporting equipment of granulating process to help you finish the
granulating much better.
Such as the mixer,feeding machine,the crush machine,the screening
machine,drying/cooling machine,conveyor and so on.
Features
1) Granular strength can be adjusted by adjusting the pressure of
roller, control strength of final products.
2) Cycle operations to achieve continuous production. High yield of
finished products.
3) Materials are force to compress molding by mechanical pressure,
without any additives, the product’s purity is guaranteed.
4) Dry powders are granulated directly without follow-up drying
process, the existing production process is easy to convergence &
transformation.
5) Granular strength is high, compared with other granulating
methods, the improvement sof bulk density are
significant,especially for the occasion where increase the
proportion of product accumulation.
6) A wide range of raw materials can be used, granular strength can
be freely adjusted according to different materials.
7) Compact structure, easy maintenance, simple operation, short
process, low energy consumption, high efficiency, low failure rate.
8) Control environmental pollution, reduce waste and powder
packaging costs, and improve product transport capacity.
9) Feeding device adopts frequency adjustment control, high
automation ,one can control multi-machine, has the features of low
labor intensity and long term continuous operation,etc.
