Rotary Drum Drying Process

Introduction to Rotary Drum Drying Technology

Overview of the Rotary Drum Drying Process

Rotary drum drying is a widely used method for reducing moisture in materials like sludge. Waste heat or heat exchange air enters the dryer, directly exchanging heat and mass with wet sludge in the channel. This ensures rapid evaporation while maintaining high operational efficiency.

Equipment Description for Rotary Drum Dryers

Key Components and Functionality

The rotary drum dryer is equipped with a specialized crushing device tailored to its structure, enabling rapid water evaporation from sludge. Smaller particles discharge efficiently with gases via an outer channel, while larger particles remain inside until fully dried.

Environmental Compliance in Rotary Drum Dryers

Exhaust gases are treated using deodorizers or water foam dust removal systems to meet environmental standards before release, ensuring eco-friendly operations.
