Key application of industrial filter cloth in vertical filter press for processing phosphorus tailings
—— Creating a green mining solid-liquid separation solution
In “ Green Mining ” Tailings reduction ” Resource Recycling ” Driven by policies such as "Green Mining", "Tailings Reduction", and "Resource Recycling", phosphate mining enterprises are constantly seeking breakthroughs in environmental protection and efficiency improvement in mineral processing technology. A large amount of phosphorus tailings slurry generated during mineral processing, if not effectively dewatered, will bring enormous environmental and safety pressures. Vertical filter press As a highly efficient equipment for solid-liquid separation, its role in phosphorus tailings treatment is becoming increasingly prominent. The core components supporting its operating efficiency are Industrial filter cloth and industrial filter mesh 。
I. Background and Challenges of Phosphorus Tailings Filtration
The tailings slurry produced after the phosphate flotation process generally has the following characteristics:
- High solid content, fine particle size ，some materials have a particle size of less than 20 microns;
- Contains reagent residues and acid-base corrosiveness ，high requirements for the chemical resistance of the filter cloth;
- High viscosity, difficult to peel off ，easily adheres to the surface of the filter cloth, affecting the cycle efficiency;
- High frequency operation, strong abrasion ，the filter cloth needs to withstand long-term tension, high pressure, and backwashing cycles.
These characteristics determine that only high-performance filter materials and structural designs can maintain efficient and stable operation under harsh conditions.
II. Structural Advantages and Process Characteristics of Vertical Filter Press
The vertical filter press is a highly automated device that can achieve continuous feeding - pressing - dewatering - discharging filtration equipment, especially suitable for handling materials such as tailings slurry with high volume and continuous processing requirements. Its structural features are as follows:
- Vertical filter plate arrangement ，gravity assisted filter cake shedding;
- Hydraulic closing system ，guaranteeing sealed operation under high pressure;
- Backblowing gas separation function ，reducing the residue of adhesive substances;
- Automatic filter cloth plate pulling and tensioning system ，reducing manual intervention.
As the core filtration medium, the quality of the filter cloth determines the overall filtration rate, filter cake dryness, maintenance cost, and service life of the equipment.
III. Industrial Filter Cloth / Key Technical Parameters of Filter Mesh
High-performance filter cloths should have the following core indicators:
Technical indicators

In addition, in the selection of industrial filter meshes, the filter cloths often used together have the auxiliary functions of strong structure and fast drainage.
IV. Engineering Cases and Application Effects
Taking a large phosphate mining enterprise in Guizhou as an example, its tailings filtration system consists of 8 sets of vertical filter presses, with an annual tailings processing capacity exceeding 100 ten thousand tons. After selecting the customized wear-resistant filter cloth provided by Xiamen Xiadias, the system operation performance is as follows:
- Filter cake moisture content from 38% reduced to 23% ，suitable for dry stacking or transportation;
- Single filtration cycle shortened 12% ，production efficiency increased by more than 10%；
- Filter cloth service life from the original about 3 months increased to 6~8 month ，the replacement frequency has significantly decreased;
- The failure rate during filtration is reduced, and downtime for maintenance is decreased 30% above 。
These filter cloth products typically adopt a double-layer composite structure. The outer layer undergoes modification to enhance hydrophobicity, anti-blocking performance, and filter cake stripping efficiency, adapting to the back-blowing and tensioning systems of vertical filter presses.
On the path towards efficient, green, and safe phosphogypsum tailings treatment, Industrial filter cloth and filter mesh although they are “ small components ” ，they play a “ crucial role ” 。In the future, with the continuous emergence of new materials, new structures, and new processing technologies, filter cloth will continue to release value in the field of solid-liquid separation in mining, becoming a fundamental engineering support force for green mining construction 。
