High Efficiency Roller Compactor | Dry Granulator for Pharmaceutical, Chemical and Food Industries

Product Overview

Roller Compactor, also known as Dry Granulator, is an advanced powder granulation equipment designed to convert fine powders into uniform granules through dry compaction technology. Unlike traditional wet granulation processes, this equipment does not require water addition, binder mixing, or drying procedures, which significantly simplifies the production process and reduces energy consumption.

With excellent performance in processing moisture-sensitive and heat-sensitive materials, the Roller Compactor is widely applied in pharmaceutical, chemical, nutraceutical, and food industries, especially for active ingredients requiring gentle processing conditions.

Working Principle

The raw powder material is continuously fed into the compaction chamber through a precision feeding system, including mechanical or pneumatic feeding options.

Inside the chamber, the material is compressed between two high-pressure rollers to form dense sheets or ribbons. The compacted sheets are then broken into smaller pieces by the pre-crushing system and further processed through a two-stage milling system to achieve the required granule size.

The entire granulation process is completed without adding liquid or external heat, ensuring stable product quality and maintaining the original properties of the materials.

Key Advantages & Features

1. Gentle Dry Granulation Technology

The material is formed by mechanical compression without chemical reactions. The active ingredients remain stable, making it especially suitable for heat-sensitive, moisture-sensitive, and high-value materials.

2. High Granulation Efficiency

The equipment can achieve a granulation yield of up to 85% for 8–60 mesh granules, improving production efficiency while reducing powder loss.

3. Energy Saving & Simplified Production Process

Compared with wet granulation, the dry granulation process eliminates liquid addition, drying, and related equipment requirements, helping customers reduce energy consumption and production costs.

4. Easy Maintenance and Fast Cleaning

The machine features a compact structure with fewer fastening components. Key parts are easy to assemble and disassemble, with disassembly and installation completed within approximately 8 minutes, reducing downtime during cleaning and maintenance.

5. Excellent Sealing Performance

The fully sealed design prevents powder leakage and contamination, ensuring operator safety and meeting pharmaceutical production requirements.

6. Automatic Cooling Water Return System

When the machine stops, the automatic water-return function prevents cooling water leakage during equipment disassembly and maintenance.

7. Flexible Roller Design

Different roller surface structures are available, including:

• Checker pattern roller
• Straight groove roller
• Smooth roller

This allows the equipment to adapt to different material characteristics and processing requirements.

8. Integrated Control System

The electrical control system is integrated with the main machine, simplifying installation, commissioning, and daily operation.

9. Adjustable Compression Pressure

The hydraulic system enables precise adjustment of roller pressure, allowing control over granule hardness, density, and final product quality.

10. Optimized Roller Structure

The upper and lower roller arrangement reduces the influence of gravity during feeding and compaction, ensuring uniform material distribution and consistent granule density.
