Granulator mixers

Efficient pharmaceutical granulation ensures uniform particle size, improved flowability, and consistent tablet or capsule performance across every batch. Granulation is a critical step in pharmaceutical manufacturing because it directly impacts content uniformity, compressibility, and downstream processing efficiency.

By transforming fine powders into controlled, free-flowing granules, manufacturers can improve blend homogeneity while reducing dust, segregation, and handling risks. Precise control of liquid addition, mixing energy, and process parameters is essential to maintain formulation integrity and protect active pharmaceutical ingredients (APIs).

Our pharmaceutical granulating solutions support pharmaceutical, nutraceutical, and healthcare production in both batch and continuous manufacturing environments.

What are pharmaceutical granulating used for?

Pharmaceutical granulating systems are used to convert powder blends into uniform granules to improve processing performance and final dosage consistency.

Typical applications include:

• Tablet granules
• Capsule fill materials
• Effervescent formulations
• Controlled-release formulations
• Nutraceutical products
• High-potency and low-dose formulations
• Cosmetic and healthcare solid dosage products
• Sachets and powder sticks

Proper granulation enhances flow properties, improves compressibility, and ensures consistent API distribution. Proper drying improves flowability, compressibility, and long-term stability while reducing degradation risks.

Typical pharmaceutical granulation process flow

Here is how granulation works in pharmaceutical production:

• Material feeding
  Powdered excipients and APIs are accurately dosed into the granulation system under controlled conditions.
  
• Dry mixing
  Uniform blending ensures even API distribution before liquid binder addition.
  
• Binder addition
  A granulating liquid is introduced in a controlled manner to initiate particle agglomeration.
  
• Wet massing and growth
  Mechanical energy promotes granule formation and growth to achieve the desired particle size.
  
• Granule sizing (if required)
  Wet granules may be milled or sized to ensure uniform structure before drying.
  
• Discharge for downstream processing
  Milling, compression, encapsulation, or further processing.
