High Performance Roller Compactor Dry Granulator for Powder Materials

Advanced Dry Granulation Solution for Pharmaceutical, Chemical and Food Production

The Roller Compactor Dry Granulator is an innovative powder processing machine that transforms fine powder materials into uniform granules through high-pressure mechanical compaction.

Unlike traditional wet granulation equipment, this dry granulation system does not require water, organic solvents, binders, or drying procedures. It provides a more efficient and environmentally friendly solution for manufacturers producing pharmaceutical, chemical, food, and nutraceutical products.

The equipment is particularly suitable for heat-sensitive, moisture-sensitive, and high-value active ingredients, where maintaining material stability and quality is critical.

Working Process

The powder material is continuously fed into the compaction chamber through a precision feeding system.

Under controlled hydraulic pressure, two counter-rotating rollers compress the powder into dense sheets (ribbons). The compacted sheets are then pre-crushed and processed through a two-stage milling system to achieve the required granule size.

The complete process includes:

Powder Feeding → High Pressure Compaction → Ribbon Breaking → Milling → Granule Collection

The dry granulation process avoids thermal stress and moisture exposure, ensuring consistent product quality.

• Outstanding Features

  1. Stable Material Properties

  The granulation process relies on mechanical force rather than chemical binders. The molecular structure and active components of the material remain unchanged.

  It is ideal for:

  • Heat-sensitive drugs
  • Moisture-sensitive ingredients
  • Active pharmaceutical ingredients (API)
  • High-value powders
