The granulator machine is a vital piece of equipment in the pharmaceutical industry, used to convert fine powders into uniform granules. These granules are easier to compress into tablets, improve flow properties, and enhance the homogeneity of the final product. The granulation process can involve either dry or wet methods, depending on the material and application.

Types of Granulator Machines for Pharmaceuticals

Wet Granulator

Uses a binding solution to aggregate powders into granules.

Suitable for materials that require moisture to bind.

Commonly used for tablet and capsule production.

Dry Granulator

Compresses powders into sheets or ribbons using high pressure, then breaks them into granules.

Ideal for moisture-sensitive or heat-sensitive materials.

Used in roller compaction or slugging processes.

Fluidized Bed Granulator

Combines drying, mixing, and granulating processes in one unit.

Uses hot air and binder spraying for granulation.

Efficient for high-volume production and uniform granule quality.

High-Shear Granulator

Features a mixing bowl with impellers and choppers for rapid granulation.

Produces dense and strong granules in a short time.

Ideal for wet granulation.

Key Components of a Granulator Machine

Mixing Chamber

Holds the powder and binder solution during granulation.

Designed for uniform mixing to ensure granule consistency.

Impellers or Blades

High-speed rotating components that mix and compact the powders.

Ensure efficient granule formation.

Screen or Sieves

Regulate the size of granules by passing the mixture through perforated plates or meshes.

Ensures uniform particle size.

Feeding System

Automatically feeds powder into the granulator for consistent operation.

Prevents dust emission and material wastage.

Drying System (for Wet Granulation)

Integrated hot air or vacuum systems to remove moisture from granules after formation.

Control Panel

Allows precise adjustment of speed, temperature, and other parameters for granule quality control.
