Preconditioning process powders with dry granulation
Dry granulation offers powder processors the advantages of controlled particle size, hardness, and density. It also improves dust control and material flow characteristics and aids product solubility and dispersability. This article describes the dry granulation process and discusses its benefits in contrast with conventional preconditioning techniques.
In many process industries, ingredient materials originate as fine, light, loose powders that often flow poorly and resist blending. Some of these materials are difficult to handle and difficult to feed through volumetric metering equipment. Others raise airborne dust, prompting concerns about the working environment and product contamination.
