Granulation

Granulation is the process of forming grains or granules from a powdery or solid substance. This process is commonly used in various scientific and industrial applications, including pharmaceuticals, metallurgy, and food production.

How Granulation Works

Granulation can be achieved through several methods, including:

• Agglomeration: Powders are combined and compressed to form granules.
• Spray Granulation: A liquid binder is sprayed onto the powder, forming granules as the liquid dries.
• Fluid Bed Granulation: Particles are suspended in a fluid and the binder is sprayed onto them, leading to granule formation.

Applications of Granulation

Granulation is widely used in:

• Pharmaceuticals: Granulation is used to create tablets and capsules with consistent dosages.
• Metallurgy: Granulation is used to create metal powders and improve the flow properties of metal powders.
• Food Production: Granulation is used to create granulated sugar, salt, and other food products.
