Detailed Description
1. Process Requirements for Alumina Filtration
In the alumina production process, key processes such as red mud separation and seed washing have extremely high requirements for filtration accuracy and filter cloth performance. The alumina slurry has fine particles and strong fluidity; if the filtration accuracy is insufficient, it can easily lead to solid losses or turbid filtrate, affecting product quality. Therefore, vertical filter presses have become important solid-liquid separation equipment in the alumina industry, and high-performance filter cloths are one of their core components.
2. Key Performance of Vertical Filter Press Filter Cloths
The filter cloths provided by Xiamen Citius for vertical filter presses are specially developed for the alumina filtration process and have the following characteristics:
- Ultra-high retention accuracy: The filter cloth uses precision weaving technology, with a uniform pore size distribution, effectively retaining fine particles, ensuring the clarity of the filtrate, and improving product purity.
- High-strength wear-resistant material: Made from high-strength polyamide (PA) or polypropylene (PP) filter cloth, resistant to high pressure and wear, suitable for long-term high-load operation.
- Excellent chemical corrosion resistance: Resistant to strong alkaline environments, suitable for high-temperature strong alkaline process conditions in Bayer alumina production, ensuring stable filtration performance.
- Good filter cake release properties: Smooth surface treatment reduces filter cake adhesion, improves discharge efficiency, reduces downtime, and increases equipment operation rate.
- Low clogging and easy to clean: Unique weaving structure reduces particle embedding, improves regeneration performance, extends service life, and reduces replacement frequency.
3. Application Advantages
- Improved filtration efficiency: Optimizing the filter cloth structure design increases the filtration flux per unit time, enhancing overall production efficiency.
- Reduced production costs: Reduces solid losses, increases alumina recovery rate, while extending filter cloth life and lowering operating costs.
- Adaptability to different process requirements: Customized filter cloth solutions can be provided according to different filtration stages in the alumina production process, ensuring optimal filtration results.
4. Conclusion
Alumina production has strict requirements for filtration accuracy and durability, and the choice of vertical filter press filter cloth directly affects separation efficiency and production efficiency.
