Containing Vibrating Screen Dust Control in Indonesian Pharmaceutical Processing

The Challenge: An Indonesian pharmaceutical manufacturer specializing in fine powder processing encountered significant dust control challenges during their precision screening operations. Their existing vibrating screen generated visible dust clouds at both feeding and discharge points, creating cross-contamination risks and failing GMP compliance standards. “Our quality team rejected batches due to potential contamination, and workers wore full PPE just to operate the equipment,” their production supervisor explained.

What Was Really Going Wrong?

Our engineering team identified three critical flaws in their current setup:

• Inadequate Sealing Structure: Conventional covers couldn’t contain ultrafine pharmaceutical powders.
• Pressure Imbalance: Natural airflow during operation pushed particles through every gap.
• Missing Integration Points: No proper interface for their existing cleanroom dust collection system.

Our Precision Solution:

We delivered a custom-engineered circular vibrating screen with complete containment features:

• GMP-Grade Enclosure System: Hermetically sealed design with silicone gaskets on all contact surfaces; Quick-release clamps with safety interlocks for maintenance access;Pharmaceutical-grade transparent viewing windows.
• Integrated Negative Pressure Control: Pre-installed ISO-standard flanges for direct dust collector connection; Balanced airflow design maintaining constant -5 to -10 Pa internal pressure;HEPA-filter compatible discharge systems.
• Clean Material Handling Interfaces: Flexible charging connectors with dust containment sleeves; Optional vacuum feeding systems for complete transfer sealing; Sanitary-grade discharge valves with zero leakage guarantee.

Operational Results:

After installation and validation::

• Zero visible dust emissions during 24/7 screening operations.
• Environmental monitoring passed all GMP audits.
• Operator comfort significantly improved with reduced PPE requirements.
