Product Overview

The New Solid Dosage Granulating and Drying Line integrates wet mixing and granulation, wet sizing, fluid-bed drying, dry sizing, material transfer and final blending for solid-dosage production. The coordinated arrangement reduces intermediate handling between process stages.

Working Principle

Material is transferred through the configured sequence of wet mixing and granulation, wet sizing, fluid-bed drying, dry sizing, screening and final blending. Connected conveying and lifting equipment moves the material between stages in accordance with the selected production-line arrangement.

After the materials are weighed, they are negatively drawn by a vacuum feeder into a wet granulator. The binder liquid is atomized through a pressure feeding tank and spray nozzle into the wet granulator, where it mixes with the fine powder to form a soft mass. At the same time, the granulating knife cuts the soft mass into wet granules. The wet granules are then uniformly sized by a wet sizing machine. Under the negative pressure of a fluid bed dryer, the sized wet granules are suctioned into the fluid bed dryer for drying. The dried materials are discharged via a vacuum discharger, subjected to dry sizing, and then transferred into a bin blender for final mixing, after which they proceed to the subsequent processes.

After the more viscous materials are weighed, they are negatively drawn by a vacuum feeder into a wet granulator. The binder liquid is atomized through a pressure feeding tank and spray nozzle into the wet granulator, where it mixes with the fine powder to form a soft mass. At the same time, the granulating knife cuts the soft mass into wet granules. The wet granules are then uniformly sized by an oscillating granulator. Under the negative pressure of a fluid bed dryer, the sized wet granules are suctioned into the fluid bed dryer for drying. The dried materials are discharged via a vacuum discharger, subjected to dry sizing, and then transferred into a bin blender for final mixing, after which they proceed to the subsequent processes.
