Key application of horizontal vacuum belt filter cloth in the phosphate ore beneficiation industry —— High-efficiency solid-liquid separation solution for phosphogypsum
In the process of phosphate resource development and utilization, the efficient treatment of phosphogypsum is an important link in maximizing resource utilization and green production. With the tightening of environmental regulations and the increasing demand for comprehensive resource utilization, traditional tailings treatment methods are gradually being replaced by high-efficiency, continuous, and highly automated processing technologies. Among them, Horizontal vacuum belt filter with special filter cloth plays a crucial role in the solid-liquid separation of tailings in the phosphate beneficiation process.
Industry background: Challenges of phosphogypsum treatment
Phosphate ore beneficiation produces a large amount of water-containing tailings. These tailings usually have fine particle sizes, uneven distribution, contain certain clay minerals, and often exhibit high viscosity, high water content, and poor sedimentation characteristics. If not handled properly, it will not only increase the load on the tailings pond but also easily cause environmental risks. Therefore, improving the dewatering efficiency of tailings and reducing transportation and storage costs are urgent pain points that the industry needs to address.
Process scheme: Horizontal vacuum belt filter + Filter cloth combination
Horizontal vacuum belt filter With its continuous operation, high vacuum suction, and high dewatering efficiency, it has become the preferred equipment in phosphogypsum dewatering processes. The core of whether this equipment can operate efficiently and achieve stable filtration lies in the industrial filter cloth 。
Why choose belt filter cloth?
Belt filter cloth not only acts as a filter medium but also directly affects the formation of filter cake, moisture control, filtration speed, and the service life of the filter cloth. In the phosphogypsum treatment scenario, the filter cloth must meet the following requirements:
- Strong wear resistance and anti-clogging performance : To cope with the scouring and accumulation of fine particles and some hard particles in the tailings.
- Good balance between filtration accuracy and dewatering efficiency : To balance the quality of clarified liquid and the dryness of the filter cake.
- Good chemical stability : Can withstand acidic or alkaline components in phosphate slurry for a long time.
- Stable operation and easy cleanability : Ensure that it is not easy to cake and is easy to rinse and regenerate during long-term continuous operation.
Application achievements: Taking Xiamen Citius (Xiamen Citius) as an example
In multiple phosphate mining projects, Xiamen Citius (Xiamen Citius) Filter Materials Technology Co., Ltd.'s belt filter cloths have been widely used in phosphogypsum solid-liquid separation processes, showing the following outstanding advantages:
- Structural customization : The filter cloth adopts a multi-layer woven structure design, combining the mechanical advantages of single and multi-filaments, / to effectively improve filter cake peelability and tensile strength.
- Increased filtration speed 20% and above : Special surface treatment improves the filtration rate and adapts to the characteristics of tailings with different particle size distributions.
- Significantly reduced filter cake moisture content : By optimizing porosity and air permeability, the dryness of the filter cake and equipment efficiency are improved.
- Extended life and reduced maintenance costs : Excellent mechanical strength and chemical resistance support frequent cleaning and long-cycle operation.
In addition, Xiamen Citius (Xiamen Citius) has a complete filter cloth testing and pilot platform, and can provide one-to-one customized services according to the characteristics of the slurry, helping mines achieve a win-win situation in environmental protection and efficiency.
Conclusion: An important step in promoting the green utilization of phosphorus resources
Faced with increasing pressure on both resources and environmental protection, the phosphate mining industry is evolving towards intelligence, high efficiency, and low carbon. The successful application of high-performance filter cloth with horizontal vacuum belt filter not only solves the problem of phosphogypsum dewatering but also sets an example for the industry in efficient separation and resource reuse. In the future, with the continuous progress of filter material technology, its role in the phosphate ore beneficiation field will become increasingly important.
