DH Series Dry Roll Press Granulator

Notes: Rolled sheet output, finished product output is just for reference and the screen is determined according to the nature of materials.

Part Three: Raw material and Final granules
A. Examples of briquetting applications:
1. Fertilizers: potassium sulfate (SOP), potassium chloride, the Russian Red Potassium, NPK fertilizer, Ammonium Phosphate Monobasic （ MAP ）， Diammonium phosphate (DAP),ammonium chloride, potassium nitrate, ammonium sulfate, ammonium bicarbonate，ground
phosphorite，etc.
2. Powders: antioxidant, zinc oxide , Calcium chloride, Graphite, Carbon Black, Frame retardants, Dolomite, cyanuric acid, calcium hypochlorite, lead oxide, potassium carbonate,carbonate strontium, calcium chloride, dicalcium phosphate, sodium metasilicate, cryolite,aluminum fluoride, brake powder, rubber additives, silica, calcium aluminate, TSP, SSP,carnallite stone, phosphate rock, metal powder, fillers, feed additives, arsenic porphyrin insects,
nicotinic acid, nicotinic acid amine, pharmaceutical intermediates, steel-making additives,melting agent, swelling, alumina powder, phosphogypsum, FGD Gypsum, benefication agent,environmental protection materials. Etc.
3. Chemical raw material, fine chemical material such as Sodium formateHCOONa.
Part Four: Completely Granulating Line
A. The whole granulating process (it takes DH**0 for example):
1. We use mixer mix the raw material.**-Mixer
2. We use bucket elevator lift the material up to the silo.***-Bucket elevator and Silo
3. The DH**0 granulator 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**0 granulator (including three parts: dosage screw feeder, forced feeder and flaking machine.)
4. Then we get the bar shape products.So we need a crusher to crush the bar shape products into **4mm irregular granules.***-Crusher (you can decide the size of granules, we will design the size of crusher
mesh.)
5. 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 **4mm irregular shape granules successfully.*******-Rotary Screen
6. 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 dont need this, you can delete this process.)
7. The last step is automatic packaging machine. This machine will help you pack the final granular into bags. ***-Automatic Packaging Machine

Part Five: Auxiliary equipments
Crusher: Its electric engine drives the principal axis to rotate and crush blocks compressed by a flaking machine into grained materials; with two grades, the crusher can crush materials compressed by a flaking machine twice. In addition, three crushing rooms greatly increase the
crushing area.

Sieving machine: the machine adopts special balancing mode to make the screen unit get balanced inertial force in various directions in the process of movement, thus leads to small vibration, low noise and demand on strength of supporting object and it integrates advantages of circular, elliptical and reciprocating linear motions, so it is of large output, high screening efficiency, low power consumption, flexible installation and convenient sieve change.
