Mineral fertilizer pellet millIntroductionDH 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..Applied materials:1.Fertilizers: Potassium
sulfate, Potassium chloride, Ammonium sulfate,Ammonium chloride,
Russian Red potash, Potassic fertilizer, NPK, Potassium nitrate,
Manheim SOP, MAP, DAP, Ammonium bicarbonate, Ulexite,
Phosphate rock.2.Powders: White carbon black, Zinc sulfate,
Clay, Bentonite, Coco peat, Antioxidant,
Bromochlorohydantion,Sodium formate, Potassium permanganate,
Wormcast, Sodium cyanide, Sodium dichloroisocyanurate, Cyanuric
acid, Calcium hypochlorite, Calcium oxide, Limestone, Brown coal,
Zinc oxide, Steel slag, Lead oxide, Strontium sulfate, Potassium
carbonate, Carbonate strontium, Calcium chloride, Dicalcium
phosphate, Sodium metasilicate, Sodium silicate, Cryolite, Aluminum
fluoride, Aluminium oxide, Rubber additives, Silica, Calcium
aluminate, TSP, SSP, Carnallite stone, Metal powder, Fillers,
Feed additives, Nicotinic acid, Nicotinic acid amine,
Pharmaceutical intermediates, Steel-making additives, Melting
agent, Swelling, Alumina powder, Desulphurized gypsum,
Environmental protection materials. etc.Granules
pictureWorking process1). Use belt scales to weigh each raw
material according to formula.---Batching system2). Use mixer to
the raw material for more uniform feeding.---Mixer3). Use
bucket elevator lift the material up to the silo.----Bucket
elevator and Silo4). The DH SERIES COMPACTOR compress the raw
material by double rollers, it mainly depending on the mechanical
pressure to compress the dry powder, so the hardness of granular is
very high.---------DH SERIES compactor (including three parts:
dosage screw feeder, forced feeder and flaking machine.)5). Then we
get the bar shape products.6). So we need a crusher to crush the
bar shape products into 2-4mm irregular granules.----Crusher (you
can decide the size of granules, we will design the size of crusher
mesh.)7). 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. You will get the qualified 2-4mm irregular shape granules
successfully.--------Rotary Screen8). Next we use the second time
rotary screen, the purpose is we want to get better result of
irregular 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.)9).After second sieve, the granule enter into
the rotary drum for coating.You can spray some liquid or powder on
the surface of the particles to avoid clumping.-------Coating
machine9). The last step is packaging machine. This machine will
help you pack the final granular into bags. ---You can choose
25-50kg/bag Packaging Machine or TON-package
machine(800-1000kg/bag)10). Workshop dusts mainly come from the
crusher, screening and discharging port of bucket elevator, in
order to effectively remove the dust, this process uses two stages
of dust removal. A cyclone dust collector is used to remove the
larger particle dust, and then the bag dust filter is used to
remove the residual dust. The dust from the dust collector will
return to the granulation process by scraper conveyor.------ Dust

adjusting the pressure of roller, control strength of final
products.Cycle operations to achieve continuous production. High
yield of finished products.Materials are force to compress molding
by mechanical pressure, without any additives, the product's purity
is guaranteed.Dry powders are granulated directly without follow-up
drying process, the existing production process is easy to
convergence & transformation.Granular strength is high, compared
with other granulating metho
