Activated Clay Rotary Drum Dryer Capacity 10TPH-120TPH Rotary Dryer Machine

Activated clay rotary drum dryer capacity 10TPH-120TPH

1.Product Introduction Rotary drum dryer

The equipment utilizes a horizontal inclined rotary drum structure, with cylinder diameters and lengths dynamically configured based on a 10–120 TPH (tons per hour) capacity range. It features an inclination angle of 2°–5°, a rotation speed of 3–8 rpm, and an integrated multi-section combined lifting flight system.

2.Application Rotary drum dryer

• Petroleum Industry: Used for the decolorization and refining of crude oil. Dried activated bleaching earth serves as a high-efficiency decolorizing agent to remove pigments, gums, and trace impurities, enhancing oil transparency and stability.

• Edible Oil Processing: Acts as a core medium for degumming and decolorization in the refining of vegetable oils (e.g., soybean and rapeseed oil). Drying ensures the material maintains a high specific surface area and adsorption activity.

• Chemical Adsorbent Production: Serves as a catalyst carrier and a precursor for wastewater treatment adsorption materials. Drying uniformity directly impacts pore structure and adsorption capacity.

• Environmental Material Preparation: Used for the pre-treatment of modified adsorbents in industrial exhaust gas and wastewater treatment, improving regeneration efficiency and recycling rates.

3.Working Principle Rotary drum dryer

• Feeding and Pre-dispersion: Wet activated bleaching earth is uniformly fed into the drum inlet via a screw feeder, with an integrated breaking device to prevent agglomeration.

• Dynamic Drying Process: As the drum rotates at low speed, the lifting flights repeatedly raise and shower the material, forming a high-density "material curtain." Hot air enters from the feeding end (co-current drying), facilitating rapid heat and mass transfer. The internal walls utilize a ceramic composite wear-resistant coating combined with airflow turbulence structures to completely eliminate material adhesion.

• Gas-Solid Separation and Purification: Evaporated moisture and fine powders enter a cyclone separator + multi-stage baghouse dust collection system. The dust recovery rate exceeds 99.5%, and tail gas emissions comply with the GB 16297–1996 standard.

• Discharge and Cooling: Dried material is discharged and cooled via air-cooling or indirect cooling devices to prevent clumping before entering the packaging or storage stage.

4.Advantages Rotary drum dryer

• High Adaptability: Specifically designed for the high viscosity and electrostatic characteristics of activated bleaching earth, breaking the operational bottlenecks of traditional dryers for this material.

• Continuous Stable Operation: Supports 24/7 uninterrupted operation with a Mean Time Between Failures (MTBF) exceeding 8,000 hours, significantly enhancing production line utilization.

• Energy Efficiency: Utilizing a triple-pass insulated structure and hot air circulation technology, the system achieves a thermal efficiency of 68%–75%, saving over 25% energy compared to traditional single-drum dryers.

• Intelligent Control: An integrated PLC + HMI system provides real-time monitoring of drum temperature, rotation speed, feed rate, and outlet moisture, supporting remote diagnostics and cloud data uploads.

• Environmental Compliance: The fully enclosed system plus multi-stage dust collection ensures dust emission concentrations remain <10mg/m³ with zero wastewater discharge, meeting green manufacturing requirements.

• Localized Service: Local manufacturers in Henan (such as Dongding or Jiutian) provide rapid installation, commissioning, and training, with response times under 24 hours to support the chemical industry clusters in the Central Plains region.
