Product Description

• DH Series Dry Roll Press Granulator

  Part One:Technical information
  A. Working Principle:
    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.
  Further explanation-----
  Raw materials are sent into hopper by fixed quantity feeder, when two rolls parallel each other horizontally, powder materials are continuously and evenly fed in the gap between two rolls by their gravities and a forced charger, the two rollers rotate in reverse, and materials between rollers are extruded by mechanical pressure. The intermediate products are bar shape, then the crusher will crush the bar shape products into irregular granules, finally using rotary screen to sieve the final products, qualified products will be put into bags, unqualified products will be recycled mix with new material for the next granulating process.
  
  B. These are our DH series different types granulators:
  This type machine has hydraulic system which can protect the machine well. The main granulator body was composed of three parts: dosage screw feeder, forced feeder and flaking
  machine.
  1) Pre-feeder: Equipped with mechanical vibrating feed hopper with automatic control and
  timing vibration
  2) Quantitative feeder: Adopts frequency conversion adjusting speed to ensure the feeding
  accuracy.
  3) Force-feeding screw hopper: It is composed of variable frequency motor, cone helix,  stirring knife tooth and cone feeding hopper with visual glass window as well as feeding mouth assemblies and so on. Its function is to further achieve degassing and perform pressure feeding.
  4) Flaking machine: it is composed of left and right fixed bearing seats, frame structure,  two alloy steel rollers, two hydraulic oil cylinders, electric automatic pump station as well as hard tooth surface dedicated reducer and main driving motor.
  Features of our granulator:
  1.Wear resistant systems for roller surfaces are adapted to the individual requirements.
  2.The easy-to-maintain and -repair design provides for maximum availability.
  3.Efficient and safe operation by means of modern monitoring and control system.
  4.Roller pulling with roller removal device
  5.Roller with cross beam
  6.Hinged frame for quick roller exchange

  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 DH650 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 DH650 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.---------DH650 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 2-4mm 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 2-4mm 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.
