Multi mill SH-200 | Flexible Sieve Changeover, 316L Stainless Steel | T&T MACHINERY

The Multi mill SH-200 manufactured by T&T MACHINERY is commonly known in the pharmaceutical industry as a granule sizing or re-granulating machine.
It is typically used in the wet or dry granulation process to:

• Adjust and standardize granule size after uneven granulation.

• Smooth and homogenize granules for more stable tablet compression.

• Separate oversized or undersized granules and bring them back to the desired size (by using sieves with different mesh sizes).

🔧 1. Machine Structure:

Depending on the model, the most common design is the oscillating granulator type. Main components include:

• Feeding hopper: Where the non-standard granules are loaded.

• Oscillating blade system: The blade moves back and forth (or rotates) to cut and push granules through the sieve.

• Sieve (screen): A stainless-steel mesh plate with specific mesh sizes for classifying granules.

• Drive motor: Powers the blade and moving parts.

• Discharge outlet: Where standardized granules are collected.

• Machine frame and housing: Usually made of stainless steel (SS304 or SS316), meeting GMP standards.

⚙️ 2. Working Principle:

• Wet or dry granules are fed into the hopper.

• The oscillating (or rotating) blade pushes the material through the sieve.

• Granules are cut, broken down, and filtered to the desired size.

• Standardized granules are collected at the discharge outlet, while oversized granules are reprocessed or discarded.

🧪 3. Applications in the Pharmaceutical Industry:

• Sizing granules after wet granulation to ensure uniformity before drying.

• Resizing dried granules to reduce size and prevent agglomeration.

• Preparing granules for tablet compression — resulting in consistent, durable, and visually uniform tablets.

• Also applied in functional food, cosmetics, chemical, and food industries (e.g., instant tea granules, nutritional powder).
