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 as increasing porosity and specific surface area, improving thermal transmission and so on.
III. Improve the physical properties of the products (such as fluidity, Breathability, bulk density) and avoid the bad influences of segregation, pulsing, agglomeration, bridging etc. appearing in the follow-up operations (drying, screening, measurement) and the use of the process (measurement, ingredients, etc.), improving the appearance and fluidity, being convenient for storage and transportation, controlling solubility, controlling porosity and specific surface area and so on. Create the conditions for enhance the production and use of process automation and confined operations.
DH series dry roll press pelletizer 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 pellets and screening to make the lump materials into pellet materials that meet the requirements of application. Dry roll press palletizing mainly depends on the manner of external pressure to force the material going through the clearance between the two relatively turning rolls to compress into laminar particles. During course of roller pressing, the real density of the materials can increase 1.5-3 times thus reaching certain demands to pellet strength.
