Potassium Sodium Feldspar Rotary Dryer Machine Capacity 5TPH-80TPH

Potassium Sodium Feldspar Rotary Drum Dryer capacity 5TPH-80TPH

1.Product Introduction Rotary drum dryer

This dryer features a horizontal rotary drum structure. Moisture evaporation is achieved through counter-current or co-current contact between hot air and wet materials inside the drum. Its processing capacity spans from 5 TPH to 80 TPH (tons per hour). Parameters such as drum length, diameter, inclination, and rotation speed can be customized based on initial moisture content, final moisture requirements, and particle size distribution to meet various production scales.

2.Application Rotary drum dryer

• Ceramic Industry: Potassium and sodium feldspars are essential fluxing raw materials for ceramic bodies and glazes; drying enhances grinding efficiency and firing stability.

• Glass Manufacturing: As a component of glass batches, drying prevents the formation of bubbles or cracking during the melting process.

• Chemical Fillers: Used in the drying treatment of precursors for potassium and sodium salt production.

• Non-Metallic Mineral Processing: Suitable for the large-scale drying of minerals such as quartz sand, kaolin, and various feldspar groups.

3.Working Principle Rotary drum dryer

• Feeding: Wet feldspar materials are uniformly fed into the interior of the drum from the inlet end via a belt conveyor.

• Agitation: The drum is installed at a slight incline (typically 2°–5°) and rotates slowly (2–8 rpm). Internal lifting flights continuously lift and shower the material, forming a uniform "material curtain."

• Heat Exchange: High-temperature hot air (usually provided by coal-fired, gas-fired, or hot blast stoves at temperatures of 300–600°C) makes counter-current or co-current contact with the material, rapidly evaporating moisture.

• Discharge & Filtration: The dried material is discharged from the outlet, while the humid air is drawn into a dust collection system (such as a baghouse filter) by an induced draft fan for purification before being released.

• Quality Control: Final moisture content can be controlled below 0.5%, meeting the requirements for subsequent milling or batching.

4.Advantages Rotary drum dryer

• Powerful Throughput: The wide capacity range of 5–80 TPH covers everything from small/medium to large-scale production lines, with a modular design facilitating expansion.

• Stable & Reliable Operation: The drum is manufactured from high-temperature resistant alloy steel with a durable supporting tire/roller structure, suitable for 24/7 continuous operation.

• High Thermal Efficiency: Multi-sectional lifting flight designs enhance heat exchange, achieving thermal energy utilization rates of over 70%.

• High Level of Automation: Can be integrated with automatic control systems for temperature, humidity, rotation speed, and feed volume, enabling unattended operation.

• Broad Adaptability: Compatible with various heat sources (natural gas, coal, biomass, or electric heating) to balance environmental compliance and cost requirements.

• Convenient Maintenance: Features rationally designed inspection doors and easily replaceable key components, ensuring minimal downtime.
