RE: Fertilizer granulatorProduct Description of NPK Fertilizer Granulator (DH450)
The importance of NPK Fertilizer Granulator technology as oneof the most important branches of powder particles processing treatmentis increasingly clear with the demand of environment protection and theimprovement of automation of the production process. "powder productpalletizing" has become the necessary trend of powder-after-processingtechnology in the world.
The significance of pellet strength processing to the powder product is embodied in the three main areas:
I. Reduce dust pollution and improve working conditions of operation.
II. Meet the requirements of production processes, such asincreasing porosity and specific surface area, improving thermaltransmission and so on.
III. Improve the physical properties of the products (such asfluidity, breathability, bulk density) and avoid the bad influences ofsegregation, pulsing, agglomeration, bridging etc. Appearing in thefollow-up operations (drying, screening, measurement) and the use of theprocess (measurement, ingredients, etc. ), improving the appearance andfluidity, being convenient for storage and transportation, controllingsolubility, controlling porosity and specific surface area and so on.Create the conditions for enhance the production and use of processautomation and confined operations.
DH series dry roll press granulator adopts dry rollingtechnology to compress the powdery materials with moisture content <=5% into pieces or tablets, then going through the processes of breakinginto pellets and screening to make the lump materials into pelletmaterials that meet the requirements of application. Dry roll pressgranulating mainly depends on the manner of external pressure to forcethe material going through the clearance between the two relativelyturning rolls to compress into laminar particles. During course ofroller pressing, the real density of the materials can increase 1.5-3times thus reaching certain demands to pellet strength.
